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 R
L
= 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 V
CC+
+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.
