The devices are internally adjusted to provide very narrow dispersion of AC and DC parameters, especially power consumption, product gain bandwidth and slew rate.
The TSV630 provides a shutdown function.
Both the TSV630 and TSV631 have a high tolerance to ESD, sustaining 4 kV for the human body model.
Description
The TSV630 and TSV631 devices are single operational amplifiers offering low voltage, low power operation and rail-to-rail input and output.
With a very low input bias current and low offset voltage (500 µV maximum for the A version), the TSV630 and TSV631 are ideal for applications that require precision. The devices can operate at power supplies ranging from 1.5 to 5.5 V, and are therefore ideal for battery-powered devices, extending battery life.
These products feature an excellent speed/power consumption ratio, offering a 880 kHz gain bandwidth while consuming only 60 µA at a 5-V supply voltage. These op-amps are unity gain stable for capacitive loads up to 100 pF.
Additionally, they are offered in micropackages, SC70-6 and SOT23-6 for the TSV630 and SC70-5 and SOT23-5 for the TSV631. They are guaranteed for industrial temperature ranges from -40° C to +125° C.
All these features combined make the TSV630 and TSV631 ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering.

1.All voltage values, except differential voltages, 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: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins 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), done for all couples of pin combinations with other pins floating.
9.Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground.
