UPC251, UPC1458

General Purpose Dual Operational Amplifiers

DESCRIPTION

UPC251, 1458 are dual general purpose operational amplifiers having internal frequency compensating

circuits. They are intended for a wide range of analog applications. High common mode voltage range and no

latch up tendencies make these amplifiers ideal for use as a voltage follower.

Depending on operating ambient temperature, UPC251 is suited for communication application while

UPC1458 is for general purposes usage.
