DESCRIPTION

The TS271 is a low cost, low power single opertional 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 I SET

■ CONSUMPTION CURRENT AND DYNAMIC PARAMETERS ARE STABLE REGARDING THE VOLTAGE POWER SUPPLY VARIATIONS

■ OUTPUT VOLTAGE CAN SWING TO GROUND

■ VERY LARGE I SET RANGE

■ STABLE AND LOW OFFSET VOLTAGE

■ THREE INPUT OFFSET VOLTAGE SELECTIONS
