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.

1.All voltages values, except differential voltage are with respect to network group terminal.

2.Differential voltages are non-inverting input terminal with respect to the inverting input terminal.

3.Short-circuits can cause excessive heating and destructive dissipation.

4.Human body model: 100 pF discharged through a 1.5 kΩ resistor into pin of device.

5.Machine model ESD: a 200 pF capacitor is charged to the specified voltage, then discharged directly into the IC with no external series resistor (internal resistor < 5 Ω), into pin-to-pin of device.
