Description

The TS95x family are rail-to-rail BiCMOS
operational amplifiers optimized and fully
specified for 3V and 5V operation.

The TS951 is housed in the space-saving 5-pin
SOT23 package that makes it well suited for
battery-powered systems. This micropackage

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

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

> ±1V, the maximum input current must not exceed ±1mA. In this case (Vid > ±1V), an input series

id

resistor must be added to limit input current.

3. Do not exceed 14V.

4. Short-circuits can cause excessive heating and destructive dissipation. Rth are typical values.

5. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a

1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.

6. Machine model: A 200pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5Ω). This is done for all couples of
connected pin combinations while the other pins are floating.

7. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.
