Applications Battery-powered applications Portable devices Signal conditioning Active filtering Medical instrumentation Automotive applications
DescriptionThe TSV91x operational amplifiers offer low
voltage operation and rail-to-rail input and output,
as well as an excellent speed/power consumption
ratio, providing an 8 MHz gain-bandwidth product
while consuming only 1.1 mA maximum at 5V.
The op-amps are unity gain stable and feature an
ultra-low input bias current.
The devices are ideal for sensor interfaces,
battery-supplied and portable applications, as
well as active filtering.

2/22 Doc ID 12584 Rev 8 Absolute maximum ratings and operating conditions
Table 2. Absolute maximum ratings All voltage values, except differential voltage, are with respect to network ground terminal. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. VCC-Vin must not exceed 6V. Input current must be limited by a resistor in series with the inputs. Short-circuits can cause excessive heating and destructive dissipation. Rth are typical values. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating. Machine model: 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). This is done for all couples of
connected pin combinations while the other pins are floating. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.

3 Application information
3.1 Driving resistive and capacitive loads
These products are low-voltage, low-power operational amplifiers optimized to drive rather
large resistive loads above 2 kΩ.
In a follower configuration, these operational amplifiers can drive capacitive loads up to
100 pF with no oscillations. When driving larger capacitive loads, adding a small in-series
resistor at the output can improve the stability of the device (Figure 18 shows the
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.
Figure 18. In-series resistor vs. capacitive load
3.2 PCB layouts
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible
to the power supply pins.
3.3 Macromodel
An accurate macromodel of the TSV91x is available on STMicroelectronics’ web site at
. This model is a trade-off between accuracy and complexity (that is, time
simulation) of the TSV91x operational amplifiers. It emulates the nominal performances of a
typical device within the specified operating conditions mentioned in the datasheet. It helps
to validate a design approach and to select the right operational amplifier, but it does not
replace on-board measurements.
