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 11 µA at 5 V. These features make the TSV61x family ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering.

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. Table 2.
