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, battery-supplied 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.

6.Rth are typical values.

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.
