supplies. Unlike traditional metal-gate CMOS
IN – –
operational amplifiers, these devices utilize Texas
Instruments silicon-gate LinCMOS 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 common-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 i...
