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.
