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/ms) 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.

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.
