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.

7. 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.
8. 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.
9. 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.
