Description
The TS951, TS952 and TS954 family of devices
are rail-to-rail BiCMOS operational amplifiers
optimized and fully specified for 3 V and 5 V
operation.
The TS951 is housed in the space-saving 5-pin
SOT23 package that makes it well-suited for
battery-powered systems. This micropackage
simplifies the PC board design because of its
ability to be placed in tight spaces (outside
dimensions are: 2.8 mm x 2.9 mm).

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
> ±1 V, the maximum input current must not exceed ±1 mA. In this case (Vid > ±1 V), an input series
id
resistor must be added to limit input current.
3. Do not exceed 14 V.
4. Short-circuits can cause excessive heating and destructive dissipation. Rth are typical values.
5. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ 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 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 Ω). 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.
