Quad Precision Single Supply Micropower Operational Amplifier

The TLC27L4x and TLC27L9 quad op amps

combine a wide range of input offset-voltage grades with low offset-voltage drift,

high input impedance, extremely low power, and high gain. The TLC27Lx use TI’s

silicon-gate LinCMOS™ technology,

providing offset-voltage stability far exceeding the stability with conventional

metal-gate processes.

Four offset voltage grades are

available (C-suffix and I-suffix), ranging from the low-cost TLC27L4 (10mV) to the

high-precision TLC27L9 (1000µV). The extremely high input impedance and low bias

currents, along with good common-mode rejection and supply-voltage rejection, and

low power consumption, make the TLC27Lx a good choice for new state-of-the-art

designs and upgrading existing designs.

In general, many features associated

with bipolar technology are available in LinCMOS op amps, 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 TLC27Lx. The devices also exhibit

low-voltage, single-supply operation, making the TLC27Lx an excellent choice for

remote and inaccessible battery-powered applications. The common-mode input-voltage

range includes the negative rail.

The TLC27Lx incorporate internal

ESD-protection circuits that prevent functional failures at voltages up to 2000V as

tested under MIL-STD-883C, Method 3015.2. Exercise care when handling these devices

because exposure to ESD potentially degrades device parametric performance.

C-suffix devices are characterized for

operation from 0°C to 70°C. I-suffix devices are characterized for operation from

–40°C to +85°C.
