Difference Amplifiers Selection Guide
The INA159 is a level translation difference amplifier. It acts as a translator between ±10V
levels and the input of single-supply ADCs typically operating at 5V. The INA159 accomplishes
this with a gain of 0.2 along with a convenient voltage-divider reference input simplifying the
biasing of the INA159’s quiescent output to the optimum point for the ADC. The INA159 has a
robust output stage, excellent frequency response and high slew rate.
