Description
The TSV630 and TSV631 devices are single
operational amplifiers offering low voltage, low
power operation and rail-to-rail input and output.
With a very low input bias current and low offset
voltage (500 µV maximum for the A version), the
TSV630 and TSV631 are ideal for applications
that require precision. The devices can operate at
power supplies ranging from 1.5 to 5.5 V, and are
therefore ideal for battery-powered devices,
extending battery life.
These products feature an excellent speed/power
consumption ratio, offering a 880 kHz gain
bandwidth while consuming only 60 µA at a 5-V
supply voltage. These op-amps are unity gain
stable for capacitive loads up to 100 pF.
The devices are internally adjusted to provide
very narrow dispersion of AC and DC parameters,
especially power consumption, product gain
bandwidth and slew rate.
The TSV630 provides a shutdown function.
Both the TSV630 and TSV631 have a high
tolerance to ESD, sustaining 4 kV for the human
body model.
Additionally, they are offered in micropackages,
SC70-6 and SOT23-6 for the TSV630 and
SC70-5 and SOT23-5 for the TSV631. They are
guaranteed for industrial temperature ranges from
-40° C to +125° C.
All these features combined make the TSV630
and TSV631 ideal for sensor interfaces,
battery-supplied and portable applications, as
well as active filtering.

all couples of pin combinations with other pins 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), 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
