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.

3 Application information
Application information
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
VCC 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 from VDD -0.1 V to VCC +0.1 V. The transition between the two pairs appears at
VCC -0.7 V. In the transition region, the performance of CMRR, PSRR, Vio and THD is
slightly degraded (as shown in Figure 16 and Figure 17 for Vio vs. Vicm).

3.3 Rail-to-rail output
The operational amplifiers’ output levels can go close to the rails: 35 mV maximum above
and below the rail when connected to a 10 kΩ resistive load to VCC/2.
