description

The TLC254, TLC254A, TLC254B, TLC25L4,

TLC254L4A, TLC254L4B, TLC25M4, TLC25M4A

and TL25M4B are low-cost, low-power quad

operational amplifiers designed to operate with

single or dual supplies. These devices utilize the

Texas Instruments silicon gate LinCMOS

process, giving them stable input-offset voltages that are available in selected grades of 2, 5, or 10 mV

maximum, very high input impedances, and extremely low input offset and bias currents. Because the input

common-mode range extends to the negative rail and the power consumption is extremely low, this series is

ideally suited for battery-powered or energy-conserving applications. The series offers operation down to a

1.4-V supply, is stable at unity gain, and has excellent noise characteristics.

These devices have internal electrostatic-discharge (ESD) protection circuits that prevent catastrophic failures

at voltages up to 2000 V as tested under MIL-STD-883C, Method 3015.1. However, care should be exercised

in handling these devices as exposure to ESD may result in degradation of the device parametric performance.

Because of the extremely high input impedance and low input bias and offset currents, applications for these

devices include many areas that have previously been limited to BIFET and NFET product types. Any circuit

using high-impedance elements and requiring small offset errors is a good candidate for cost-effective use of

these devices. Many features associated with bipolar technology are available with LinCMOS operational

amplifiers without the power penalties of traditional bipolar devices.
