The TLC2872Z is a dual rail-to-rail output
12
operational amplifier manufactured using Texas
Instruments Advanced LinCMOS™ process.
These devices offer comparable ac performance

IO = 50 µA
while having better noise, input offset voltage
and power dissipation than existing CMOS
8
operational amplifiers. In addition, the common-
I_O = 500 µA
mode input voltage range is wider than typical
standard CMOS type amplifiers. To take
6
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™ 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.
