Description
The TSV73x series of single, dual, and quad
operational amplifiers offer low-voltage operation,
rail-to-rail input and output, and excellent
accuracy (V
io
lower than 200
μV
at 25
°
C).
These devices benefit from STMicroelectronics
®
5 V CMOS technology and offer an excellent
speed/power consumption ratio (900 kHz typical
gain bandwidth) while consuming 60
μA
typical at
5 V. The TSV73x series also feature an
ultra-low input bias current.
The single version (TSV731), the dual version
(TSV732), and the quad version (TSV734) are
housed in the smallest industrial packages.
These characteristics make the TSV73x family
ideal for sensor interfaces, battery-powered and
portable applications, and active filtering.

1. All voltage values, except the differential voltage are with respect to the network ground terminal.
2. The differential voltage is a non-inverting input terminal with respect to the inverting input terminal. The
TSV732 and TSV734 devices include an internal differential voltage limiter that clamps internal differential
voltage at 0.5 V.

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.
