TS271

CMOS Programmable

Low Power Single Operational Amplifier

■ Offset null capability (by external

compensation)

■ Dynamic characteristics adjustable ISET

■ Consumption current and dynamic

parameters are stable regarding the

voltage power supply variations

■ Output voltage can swing to ground

■ Very large ISET range

■ Stable and low offset voltage

■ Three input offset voltage selections

Description

The TS271 is a low cost, low power single

operational amplifier designed to operate with

single or dual supplies. This operational amplifier

uses the ST silicon gate CMOS process giving it

an excellent consumption-speed ratio. This

amplifier is ideally suited for low consumption

applications.

The power supply is externally programmable with

a resistor connected between 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 8, Figure 19, Figure 30.
