Description
The TSV91x operational amplifiers offer low
voltage operation and rail-to-rail input and output,
as well as an excellent speed/power consumption
ratio, providing an 8 MHz gain-bandwidth product
while consuming only 1.1 mA maximum at 5 V.
The op-amps are unity gain stable and feature an
ultra-low input bias current.
The devices are ideal for sensor interfaces,

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.
3. VCC-Vin must not exceed 6 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. R
are typical values.
th
7. Human body model: a 100 pF 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.
8. 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.
9. 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.
