Hey, I am currently using AD8553 with a gain of 1 to output a single signal that represents the difference between Vin+ and Vin- but it only outputs 1V even after changing the input.
The input to AD8553 comes from LTC1968; the LTC1968 outputs max DC voltage of 0.8V. Therefore, both the input( Vin+ and Vin- ) will be less than 0.8V.
I have checked the datasheet and it does mention that for a 5V source, the input range is between 0V to 3.3V which is what I want.
AD8553 datasheet: https://www.analog.com/media/en/technical-documentation/data-sheets/AD8553.pdf
I have used the following configuration, and I only get 1V output even after changing the input. I am not sure what I have missed.
Please help out.
I hope to hear your inputs on this.
I will try using a different instrumentation amplifier but not sure what I have missed here as I have taken into consideration the input voltage range and the single power supply.
