SC70-5/SOT23-5
The TSV620, TSV620A, TSV621, and TSV621A
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 (800 µV maximum for the A version), the
TSV62x is ideal for applications requiring
precision. The device can operate at a power
supply ranging from 1.5 to 5.5 V, and therefore
suit battery-powered devices and extend their
battery life.
This product features an excellent speed/power
consumption ratio, offering a 420 kHz gain
bandwidth while consuming only 29 µA at a
5 V supply voltage.
These operational amplifiers are unity gain stable
for capacitive loads up to 100 pF.
The device is internally adjusted to provide very
narrow dispersion of AC and DC parameters,
especially power consumption, product gain
bandwidth, and slew rate.
The TSV62x present high tolerance to ESD,
sustaining 4 kV for the human body model.
The device is offered in macropackages, SC70-6
and SOT23-6 for the TSV620 and
SC70-5 and SOT23-5 for the TSV621. They are
guaranteed for industrial temperature ranges from
-40 °C to 125 °C.
All these features make the TSV620, TSV620A,
TSV621, and TSV621A ideal for sensor
interfaces, battery-supplied and portable
applications, as well as active filtering.

1. All voltage values, except differential voltage are with respect to network ground terminal.
2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal.
3. Vcc-Vin must not exceed 6 V.
4. Input current must be limited by a resistor in series with the inputs.
5. Vcc-SHDN must not exceed 6 V.
6. Short-circuits can cause excessive heating and destructive dissipation.
7. R
th
are typical values.
8. 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.
9. Machine mode: 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.
10. Charged device model: all pins plus package are charged together to the specified voltage and then
discharged directly to the ground.
