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.
