description
The TLV234x operational amplifiers are in a family
of devices that has been specifically designed for
use in low-voltage single-supply applications.
Unlike other products in this family designed
primarily to meet aggressive power consumption
specifications, the TLV234x was developed to
offer ac performance approaching that of a BiFET
operational amplifier while operating from a
single-supply rail. At 3 V, the TLV234x has a
typical slew rate of 2.1 V/
s and 790-kHz
unity-gain bandwidth.
Each amplifier is fully functional down to a
minimum supply voltage of 2 V and is fully
characterized, tested, and specified at both 3-V
and 5-V power supplies over a temperature range
of 40
C to 85
C. The common-mode input
voltage range includes the negative rail and
extends to within 1 V of the positive rail.

description (continued)
Low-voltage and low-power operation has been made possible by using the Texas Instruments silicon-gate
LinCMOS technology. The LinCMOS process also features extremely high input impedance and ultra-low input
bias currents. These parameters combined with good ac performance make the TLV234x effectual in
applications such as high-frequency filters and wide-bandwidth sensors.
To facilitate the design of small portable equipment, the TLV234x is made available in a wide range of package
options, including the small-outline and thin-shrink small-outline packages (TSSOP). The TSSOP package has
significantly reduced dimensions compared to a standard surface-mount package. Its maximum height of only
1.1 mm makes it particularly attractive when space is critical.
The device inputs and outputs are designed to withstand 100-mA currents without sustaining latch-up. The
TLV234x incorporates internal ESD-protection circuits that prevents functional failures at voltages up to
2000 V as tested under MIL-PRF-38535, Method 3015.2; however, care should be exercised in handling these
devices as exposure to ESD may result in the degradation of the device parametric performance.
TLV2342Y chip information
This chip, when properly assembled, displays characteristics similar to the TLV2342. Thermal compression or
ultrasonic bonding may be used on the doped-aluminum bonding pads. Chips may be mounted with conductive
epoxy or a gold-silicon preform.

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 network ground.
2. Differential voltages are at the noninverting input with respect to the inverting input.
3. The output may be shorted to either supply. Temperature and /or supply voltages must be limited to ensure that the maximum
dissipation rating is not exceeded (see application selection).
