Wide bandwidth (550kHz in G = 10) and high slew rate (6.5V/µs) 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. RG 1 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°...
