Description

The TS461, TS462 and TS464 family of

operational amplifiers can operate with voltages

as low as ±1.35 V and reach a minimum of

±2 Vpp of output swing when supplied with

±2.5 V.

The devices are well-suited to all kinds of portable

and battery-supplied equipment, where low noise

and low distortion are key requirements.

The TS461, TS462 and TS464 offer excellent

output rail-to-rail performances at an attractive

cost.
