Description
The TSV912H and TSV912AH operational amplifiers offer low voltage operation and rail-to­rail input and output.
The devices feature an excellent speed/power consumption ratio, offering an 8 MHz gain­bandwidth product while consuming only 1.1 mA maximum at 5 V. They are unity gain stable and feature an ultra-low input bias current.
The TSV912H is a high temperature version of the TSV912, and can operate from -40°C to +150°C with unique characteristics. Its main target applications are automotive, but the device is also ideal for sensor interfaces, battery­supplied and portable applications, as well as active filtering.

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.

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.
