DESCRIPTION
The INA156 is a low-cost CMOS instrumentation
amplifier with rail-to-rail output swing optimized for
low-voltage, single-supply operation.
Wide bandwidth (550kHz in G = 10) and high slew
rate (6.5V/ s) make the INA156 suitable for driving
sampling A/D converters as well as general purpose
and audio applications. Fast settling time allows use
with higher speed sensors and transducers, and rapid
scanning data acquisition systems.

APPLICATIONS
Gain can be set to 10V/V or 50V/V by pin strapping.
Gains between these two values can be obtained with
the addition of a single resistor. The INA156 is fully
specified over the supply range of +2.7V to +5.5V.
The INA156 is available in an MSOP-8 surface-mount
package specified for operation over the temperature
range –55 C to 125 C.
