description
The TLC2872Z is a dual rail-to-rail output
operational amplifier manufactured using Texas
Instruments Advanced LinCMOS
TM
process.
These devices offer comparable ac performance
while having better noise, input offset voltage
and power dissipation than existing CMOS
operational amplifiers. In addition, the common-
mode input voltage range is wider than typical
standard CMOS type amplifiers. To take
advantage of this improvement in performance,
making this device available for a wider range of
applications, V
ICR
is specified with a larger
maximum input offset voltage test limit of
5 mV.
The Advanced LinCMOS
TM
process uses a
silicon-gate technology to obtain input offset voltage stability with temperature and time that far exceeds that
obtainable using metal-gate technology. Also, this technology makes possible input impedance levels that meet
or exceed levels offered by top-gate JFET and expensive dielectric-isolated devices.
The TLC2872Z, manufactured using Texas Instruments high-temperature process flow, allows extended
temperature operation up to 150
C in a plastic package. This adds extra reliability at the extended temperature
and reduces the need for expensive hermetically sealed ceramic packages.
The TLC2872Z, which exhibits high input impedance and low noise, is excellent for small signal conditioning
of high impedance sources, such as piezoelectric transducers. In addition, the rail-to-rail output feature with
single or split supplies makes this device a great choice for inputs to ADCs in either the unipolar or bipolar mode
of operation. This feature, combined with its temperature performance, makes the TLC2872Z ideal for
sonobuoys, pressure sensors, temperature controls, active VR sensors, accelerometers, and many other
applications.

description (continued)
The inputs and outputs of this device are designed to withstand 100-mA surge current without sustaining
latch-up. In addition, internal ESD-protection circuits prevent functional failures up to 2000 V. The device is
characterized for operation over the extended (Z) temperature range of 40
C to 150
C.
TLC2872Y chip information
This chip, when properly assembled, displays characteristics similar to TLC2872Z. 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. Differential voltages are at IN+ with respect to IN . Excessive current will flow if input is brought below VDD 0.3 V.
2. All voltage values, except differential voltages, are with respect to the midpoint between VDD + and VDD .
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.
