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/µs) 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.
