Description
The TSV6290 and the TSV6291 are single
operational amplifiers with a high bandwidth while
consuming only 29 µA. They must be used in a
gain configuration (G<-3, G>+4).

The TSV6290 comes with a shutdown function.
The TSV6290 and TSV6291 present a high
tolerance to ESD, sustaining 4 kV for the human
body model.
Additionally, the TSV6290 and TSV6291 are
offered in SC70-5/6 and SOT23-5/6
micropackages, with extended temperature
ranges from -40° C to +125° C.
All these features make the TSV629x ideal for
sensor interfaces, battery-supplied and portable
applications, as well as active filtering.
With a very low input bias current and low offset
voltage (800 µV maximum for the A version), the
TSV629x family of devices is ideal for applications
requiring precision. The devices can operate at a
power supply ranging from 1.5 to 5.5 V, and
therefore suit battery-powered devices, extending
battery life.

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, 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: 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 mode: 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.
