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. G = 10 pins open G = 50 pins connected 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-...
