Description
The TSV61x family of single and dual operational
amplifiers offers low voltage, low power operation
and rail-to-rail input and output.
The devices also feature an ultra-low input bias
current as well as a low input offset voltage.
The TSV61x have a gain bandwidth product of
120 kHz while consuming only 10 µA at 5 V.
These features make the TSV61x family 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. Short-circuits can cause excessive heating and destructive dissipation.
5. Rth are typical values.
6. 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.
7. Machine model: a 200 pF cap 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.
8. Charged device model: all pins plus package are charged together to the specified voltage and then
discharged directly to ground.
