Description for the TLC27L1
The TLC27L1x operational amplifiers combine a wide range of input offset-voltage grades with low offset-voltage drift and high input impedance. In addition, the TLC27L1x is a low-bias version of the TLC271 programmable amplifier. These devices use the Texas Instruments silicon-gate LinCMOS technology, which provides offset-voltage stability far exceeding the stability available with conventional metal-gate processes.
Two offset-voltage grades are available (C-suffix and I-suffix types), ranging from the low-cost TLC27L1 (10mV) to the TLV27L1A (5mV) 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 LinCMOS 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 TLC27L1x. The devices also exhibit low-voltage, single-supply operation, making them an excellent choice for remote and inaccessible battery-powered applications. The common-mode input-voltage range includes the negative rail.
The TLC27L1x incorporate internal electrostatic-discharge (ESD) protection circuits that prevent functional failures at voltages up to 2000V as tested under MIL-STD-883C, Method 3015.2. However, exercise care when handling these devices because exposure to ESD can 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.
