DESCRIPTION

The INA155 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 INA155 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 INA155 is fully

specified over the supply range of +2.7 to +5.5V.

The INA155 is available in MSOP-8 and SO-8 surface-

mount packages. Both are specified for operation

over the temperature range –55°C to 125°C.
