Universal OpAmp EVM
description
The TLV411x single supply operational amplifiers provide output currents in excess of 300 mA at 5 V. This
enables standard pin-out amplifiers to be used as high current buffers or in coil driver applications. The TLV4110
and TLV4113 comes with a shutdown feature.
The TLV411x is available in the ultra small MSOP PowerPAD
TM
package, which offers the exceptional thermal
impedance required for amplifiers delivering high current levels.
All TLV411x devices are offered in PDIP, SOIC (single and dual) and MSOP PowerPAD (dual).

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltage values, except differential voltages, are with respect to GND.
2. To prevent permanent damage the die temperature must not exceed the maximum junction temperature.

APPLICATION INFORMATION
shutdown function
Two members of the TLV411x family (TLV4110/3) have a shutdown terminal for conserving battery life in
portable applications. When the shutdown terminal is tied low, the supply current is reduced to just nano amps
per channel, the amplifier is disabled, and the outputs are placed in a high impedance mode. In order to save
power in shutdown mode, an external pullup resistor is required, thererfore, to enable the amplifier the shutdown
terminal must be pulled high. When the shutdown terminal is left floating, care should be taken to ensure that
parasitic leakage current at the shutdown terminal does not inadvertently place the operational amplifier into
shutdown.
driving a capacitive load
When the amplifier is configured in this manner, capacitive loading directly on the output will decrease the
device's phase margin leading to high frequency ringing or oscillations. Therefore, for capacitive loads of greater
than 1 nF, it is recommended that a resistor be placed in series (R
NULL
) with the output of the amplifier, as shown
in Figure 24. A maximum value of 20
should work well for most applications.

general power design considerations
When driving heavy loads at high junction temperatures there is an increased probability of electromigration
affecting the long term reliability of ICs. Therefore for this not to be an issue either
D
the output current must be limited (at these high junction temperatures) or
D
the junction temperature must be limited.
The maximum continuous output current at a die temperature 150
C will be 1/3 of the current at 105
C.
The junction temperature will be dependent on the ambient temperature around the IC, thermal impedance from
the die to the ambient and power dissipated within the IC.
T
J
= T
A
+
JA
P
DIS
Where
P
DIS
is the IC power dissipation and is equal to the output current multiplied by the voltage dropped across the
output of the IC.
JA
is the thermal impedance between the junction and the ambient temperature of the IC.
T
J
is the junction temperature.
T
A
is the ambient temperature.
Reducing one or more of these factors will result in a reduced die temperature. The 8-pin SOIC (small outline
integrated circuit) has a thermal impedance from junction to ambient of 176
C/W. For this reason we
recommend that the maximum power dissipation of the 8-pin SOIC package be limited to 350 mW, with peak
dissipation of 700 mW as long as the RMS value is less than 350 mW.
The use of the MSOP PowerPAD
TM
dramatically reduces the thermal impedance from junction to case. And with
correct mounting, the reduced thermal impedance will greatly increase the IC's permissible power dissipation
and output current handling capability. For example, the power dissipation of the PowerPAD
TM
is increased to
above 1 W. Sinusoidal and pulse-width modulated output signals will also increase the output current capability.
The equivalent dc current is proportional to the square-root of the duty cycle:

Note that with an operational amplifier, a duty cycle of 70% would often result in the op amp sourcing current
70% of the time and sinking current 30%, therefore, the equivalent dc current would still be 0.84 times the
continuous current rating at a particular junction temperature.

APPLICATION INFORMATION
general PowerPAD design considerations
The TLV411x is available in a thermally-enhanced PowerPAD family of packages. These packages are
constructed using a downset leadframe upon which the die is mounted [see Figure 27(a) and Figure 27(b)]. This
arrangement results in the lead frame being exposed as a thermal pad on the underside of the package [see
Figure 27(c)]. Because this thermal pad has direct thermal contact with the die, excellent thermal performance
can be achieved by providing a good thermal path away from the thermal pad.
The PowerPAD package allows for both assembly and thermal management in one manufacturing operation.
During the surface-mount solder operation (when the leads are being soldered), the thermal pad can also be
soldered to a copper area underneath the package. Through the use of thermal paths within this copper area,
heat can be conducted away from the package into either a ground plane or other heat dissipating device.
The PowerPAD package represents a breakthrough in combining the small area and ease of assembly of
surface mount with the, heretofore, awkward mechanical methods of heatsinking.

general PowerPAD design considerations (continued)
1.
Prepare the PCB with a top side etch pattern as shown in Figure 28. There should be etch for the leads as
well as etch for the thermal pad.
2.
Place five holes (dual) or nine holes (quad) in the area of the thermal pad. These holes should be 13 mils
in diameter. Keep them small so that solder wicking through the holes is not a problem during reflow.
3.
Additional vias may be placed anywhere along the thermal plane outside of the thermal pad area. This helps
dissipate the heat generated by the TLV411x IC. These additional vias may be larger than the 13-mil
diameter vias directly under the thermal pad. They can be larger because they are not in the thermal pad
area to be soldered so that wicking is not a problem.
4.
Connect all holes to the internal ground plane.
5.
When connecting these holes to the ground plane, do not use the typical web or spoke via connection
methodology. Web connections have a high thermal resistance connection that is useful for slowing the heat
transfer during soldering operations. This makes the soldering of vias that have plane connections easier.
In this application, however, low thermal resistance is desired for the most efficient heat transfer. Therefore,
the holes under the TLV411x PowerPAD package should make their connection to the internal ground plane
with a complete connection around the entire circumference of the plated-through hole.
6.
The top-side solder mask should leave the terminals of the package and the thermal pad area with its five
holes (dual) or nine holes (quad) exposed. The bottom-side solder mask should cover the five or nine holes
of the thermal pad area. This prevents solder from being pulled away from the thermal pad area during the
reflow process.
7.
Apply solder paste to the exposed thermal pad area and all of the IC terminals.
8.
With these preparatory steps in place, the TLV411x IC is simply placed in position and run through the solder
reflow operation as any standard surface-mount component. This results in a part that is properly installed.

The next consideration is the package constraints. The two sources of heat within an amplifier are quiescent
power and output power. The designer should never forget about the quiescent heat generated within the
device, especially muti-amplifier devices. Because these devices have linear output stages (Class A-B), most
of the heat dissipation is at low output voltages with high output currents.
The other key factor when dealing with power dissipation is how the devices are mounted on the PCB. The
PowerPAD devices are extremely useful for heat dissipation. But, the device should always be soldered to a
copper plane to fully use the heat dissipation properties of the PowerPAD. The SOIC package, on the other
hand, is highly dependent on how it is mounted on the PCB. As more trace and copper area is placed around
the device,
JA
decreases and the heat dissipation capability increases. The currents and voltages shown in
these graphs are for the total package. For the dual or quad amplifier packages, the sum of the RMS output
currents and voltages should be used to choose the proper package.
