Description
The TS93x (single, dual and quad) series are operational amplifiers that can operate with voltages as low as 2.7 V and reach a 2.9 Vpp output swing with RL = 100 kΩ when supplied at 3 V.
Offering a typical consumption of only 20 μA, these devices are particularly well-suited to battery-powered applications.
The amplifiers’ space-saving 5-pin SOT23-5 package with outer dimensions of
2.8 mm x 2.9 mm make them very easy to implement on a board design.

1.All voltages values, except differential voltage are with respect to network terminal.
2.Differential voltages are non-inverting input terminal with respect to the inverting input terminal.
3.The magnitude of input and output voltages must never exceed VCC+ +0.3 V.
4.Input current must be limited by a resistor in series with the inputs.
5.Short-circuits can cause excessive heating and destructive dissipation.
6.Human body model: 100 pF discharged through a 1.5 kΩ resistor into pin of device.
7.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.
8.Charged device model: all pins and the package are charged together to the specified voltage and then discharged directly to ground through only one pin. This is done for all pins.
