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.

3.1 Operating voltages
The TSV630 and TSV631 can operate from 1.5 to 5.5 V. Their parameters are fully specified
for 1.8-, 3.3- and 5-V power supplies. However, the parameters are very stable in the full
V
range and several characterization curves show the TSV63x characteristics at 1.5 V.

Additionally, the main specifications are guaranteed in extended temperature ranges from 40° C to +125° C.
3.2 Rail-to-rail input
The TSV630 and TSV631 are built with two complementary PMOS and NMOS input
differential pairs. The devices have a rail-to-rail input, and the input common mode range is
extended fromV

3.5 Optimization of DC and AC parameters
These devices use an innovative approach to reduce the spread of the main DC and AC
parameters. An internal adjustment achieves a very narrow spread of the current
consumption (60 µA typical, min/max at
consumption value, such as GBP, SR and AVd, benefit from this narrow dispersion. All parts
present a similar speed and the same behavior in terms of stability. In addition, the minimum
values of GBP and SR are guaranteed
minimum).

3.6 Driving resistive and capacitive loads
These products are micro-power, low-voltage operational amplifiers optimized to drive rather
large resistive loads, above 2 kΩ. For lower resistive loads, the THD level may significantly
increase.
In a follower configuration, these operational amplifiers can drive capacitive loads up to
100 pF with no oscillations. When driving larger capacitive loads, adding an in-series
resistor at the output can improve the stability of the devices (see Figure 22 for
recommended in-series resistor values). Once the in-series resistor value has been
selected, the stability of the circuit should be tested on bench and simulated with the
simulation model.
Figure 22. In-series resistor vs. capacitive load
3.7 PCB layouts
For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible
to the power supply pins.
An accurate macromodel of the TSV630 and TSV631 is available on STMicroelectronics’
web site at www.st.com. This model is a trade-off between accuracy and complexity (that is,
time simulation) of the TSV63x operational amplifiers. It emulates the nominal performances
of a typical device within the specified operating conditions mentioned in the datasheet. It
also helps to validate a design approach and to select the right operational amplifier, but it does not replace on-board measurements.
