Description
The TSV6390 and TSV6391 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
TSV6390 and TSV6391 are ideal for applications
requiring 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.

When used with a gain (above -3 or +4), these
products feature an excellent speed/power
consumption ratio, offering a 2.4 MHz gain
bandwidth product while consuming only 60 µA at
a 5 V supply voltage.
The TSV6390 comes with a shutdown function.
Both the TSV6390 and TSV6391 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 TSV6390 and
SC70-5 and SOT23-5 for the TSV6391. They are
guaranteed for industrial temperature ranges from
-40° C to +125° C.
All these features combined make the TSV6390
and TSV6391 ideal for sensor interfaces,
battery-supplied and portable applications, as
well as active filtering.

3 Application information
Application information
3.1 Operating voltages
The TSV6390 and TSV6391 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 TSV639x 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 TSV6390 and TSV6391 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 VCC- -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 13 and Figure 14 for Vio vs. Vicm).

The devices are guaranteed without phase reversal.
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.
3.4 Shutdown function (TSV6390)
The operational amplifier is enabled when the SHDN pin is pulled high. To disable the
amplifier, the SHDN must be pulled down to VCC-. When in shutdown mode, the amplifier’s
output is in a high impedance state. The SHDN pin must never be left floating, but tied to
VCC+ or VCC-.
