■ Wide bandwidth
■ Low power consumption: 820 µA typ
■ Unity gain stability
■ High output current: 35 mA
■ Operating range from 2.5 to 5.5 V

Description
The TSV912H and TSV912AH operational
amplifiers offer low voltage operation and rail-to-
rail input and output.
The devices feature an excellent speed/power
consumption ratio, offering an 8 MHz gain-
bandwidth product while consuming only 1.1 mA
maximum at 5 V. They are unity gain stable and
feature an ultra-low input bias current.
The TSV912H is a high temperature version of
the TSV912, and can operate from -40°C to
+150°C with unique characteristics. Its main
target applications are automotive, but the device
is also ideal for sensor interfaces, battery-
supplied and portable applications, as well as
active filtering.

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 devices (see Figure 18 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.
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.
