TLC27L1B

The TLC27L1B operational amplifier combines a wide range of input offset-voltage grades with low offset-voltage drift and high input impedance. In addition, the TLC27L1B is a low-bias version of the TLC271 programmable amplifier. These devices use the Texas Instruments silicon-gate LinCMOSE technology, which provides offset-voltage stability far exceeding the stability available with conventional metal-gate processes.

Three offset-voltage grades are available (C-suffix and I-suffix types), ranging from the low-cost TLC27L1 (10 mV) to the TLC27L1B (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 TLC27L1B a good choice for new state-of-the-art designs as well as for upgrading existing designs.

In general, many features of TLC27L1B associated with bipolar technology are available in LinCMOSE operational 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 TLC27L1B. 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.

The TLC27L1B inputs and output are designed to withstand 100-mA surge currents without sustaining latch-up.

The TLC27L1B incorporates internal electrostatic-discharge (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 TLC27L1B as exposure to ESD may result in the degradation of the device parametric performance.
