TS271I PROGRAMMABLE CMOS SINGLE OPERATIONAL AMPLIFIERS

The TS271 is a low cost, low power single operational amplifier designed to operate with single or ORDER CODES Part Number TS271C/AC/BC TS271I/AI/BI TS271M/AM/BM Example : TS271ACN Temperature Range 0oC, +70oC -40oC, +125oC -55 C, +125 C o o Package N q q q D q q q dual supplies. This operational amplifier uses the SGS-THOMSON silicon gate CMOS process g.

Features

ectedbetween pins 8 and 4. It allows to choose the best consumption-speed ratio and supply current can be minimized according to the required speed. This device is specified for the following ISET current values : 1.5µA, 25µA, 130µA. This CMOS amplifier offers very high input impedance and extremely low input currents. The major advantage versus JFET devices is the very low input currents drift with temperature (see figure 3).
