The TSX56x, TSX56xA series of operational
amplifiers benefit from STMicroelectronics
®
16 V
CMOS technology to offer state-of-the-art
accuracy and performance in the smallest
industrial packages. The TSX56x, TSX56xA have
pinouts compatible with industrial standards and
offer an outstanding speed/power consumption
ratio, 900 kHz gain bandwidth product while
consuming only 250 µA at 16 V. Such features
make the TSX56x, TSX56xA ideal for sensor
interfaces and industrial signal conditioning. The
wide temperature range and high ESD tolerance
ease use in harsh automotive applications.

7. 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.
8. 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.
9. Charged device model: all pins plus package are charged together to the specified voltage and then
discharged directly to ground.
