DESCRIPTION  
The INA155 is a low-cost CMOS instrumentation  
amplifier with rail-to-rail output swing optimized for  
low voltage, single-supply operation.  
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.  
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.  
The INA155 is available in MSOP-8 and SO-8 sur-  
face-mount packages. Both are specified for operation  
over the temperature range –55°C to 125°C.
