描述 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.

■ 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
