Unlike traditional metal-gate CMOS - - operational amplifiers, these devices utilize Texas Instruments silicon-gate Lin CMOS process, giving them stable input offset voltages without sacrificing the advantages of metal-gate CMOS. OFFSET N1 OFFSET N2 This series of parts is available in selected grades of input offset voltage and can be nulled with one external potentiometer. Because the input mon-mode range extends to the negative rail and the power consumption is extremely low, this family is ideally suited for battery-powered or energy-conserving applications. A bias-select pin can be used to program one of three ac performance and power-dissipation levels to suit the application. The series Features operation down to a 1.4-V supply and is stable at unity gain. 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 a degradation of the device parametric performance. Because of the extremely high input impedance and low input bias and offset currents, applications for the TLC251C series include many areas that have previously been limited to BIFET and...
