description
The TLC271 operational amplifier combines a
wide range of input offset voltage grades with low
offset voltage drift and high input impedance. In
NC – No internal connection
addition, the TLC271 offers a bias-select mode
that allows the user to select the best combination of power dissipation and ac performance for a particular
application. These devices use Texas Instruments silicon-gate LinCMOStechnology, which provides offset
voltage stability far exceeding the stability available with conventional metal-gate processes.

description (continued)
Using the bias-select option, these cost-effective devices can be programmed to span a wide range of
applications that previously required BiFET, NFET, or bipolar technology. Three offset voltage grades are
available (C-suffix and I-suffix types), ranging from the low-cost TLC271 (10 mV) to the TLC271B (2 mV)
low-offset version. The extremely high input impedance and low bias currents, in conjunction with good
common-mode rejection and supply voltage rejection, make these devices a good choice for new
state-of-the-art designs as well as for upgrading existing designs.
In general, many features associated with bipolar technology are available in LinCMOSoperational amplifiers,
without the power penalties of bipolar technology. General applications such as transducer interfacing, analog
calculations, amplifier blocks, active filters, and signal buffering are all easily designed with the TLC271. The
devices also exhibit low-voltage single-supply operation, making them ideally suited for remote and
inaccessible battery-powered applications. The common-mode input voltage range includes the negative rail.
A wide range of packaging options is available, including small-outline and chip-carrier versions for high-density
system applications.
The device inputs and output are designed to withstand 100-mA surge currents without sustaining latch-up.
The TLC271 incorporates internal ESD-protection circuits that prevent functional failures at voltages up to 2000
V as tested under MIL-STD-883C, 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.
The C-suffix devices are characterized for operation from 0°C to 70°C. The I-suffix devices are characterized
for operation from 40°C to 85°C. The M-suffix devices are characterized for operation over the full military
temperature range of 55°C to 125°C.
bias-select feature
The TLC271 offers a bias-select feature that allows the user to select any one of three bias levels depending
on the level of performance desired. The tradeoffs between bias levels involve ac performance and power
dissipation (see Table 1).
