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.
