Hello,
We designed a circuit with INA826 to provide a higher voltage for a lighting drive, see the attachment. Basically, we want INA826 to amplify 0~1.2V to 31V power supply level, so we use Gain=100. But from the measurement, we found with 1.2V input we only got 27.5V output and the real gain is only 22.5. Then we adjusted gain to 50 which caused the output only 11.2V. Please advice how to get output 31V for 1.2V input. Thanks.
