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.
The TSV61x can operate from 1.5 to 5.5 V. Their parameters are fully specified for 1.8, 3.3
and 5 V power supplies. However, the parameters are very stable in the full V
several characterization curves show the TSV61x characteristics at 1.5 V. Additionally, the
main specifications are guaranteed in extended temperature ranges from -40° C to +85° C.
3.2 Rail-to-rail input
The TSV61x are built with two complementary PMOS and NMOS input differential pairs.
The devices have a rail-to-rail input, and the input common mode range is extended from

In a follower configuration, these operational amplifiers can drive capacitive loads up to
100 pF with no oscillations. When driving larger capacitive loads, adding an in-series
resistor at the output can improve the stability of the devices (see Figure 19 for
recommended in-series resistor values). Once the in-series resistor value has been
selected, the stability of the circuit should be tested on bench and simulated with the
simulation model.

3.5 PCB layouts
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible
to the power supply pins.
3.6 Macromodel
An accurate macromodel of the TSV61x is available on STMicroelectronics’ web site at
www.st.com. This model is a trade-off between accuracy and complexity (that is, time
simulation) of the TSV61x operational amplifiers. It emulates the nominal performances of a
typical device within the specified operating conditions mentioned in the datasheet. It also
helps to validate a design approach and to select the right operational amplifier, but it does not replace on-board measurements.
In order to meet environmental requirements, ST offers these devices in different grades of
