Part Number: ADS1115 Other Parts Discussed in Thread: LM358 Tool/software: I was referring the forum https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/705210/ads1115-voltage-divider-for-differential-voltage and was trying to implement the circuit by Joseph W where I have connected my ADS1115 to esp32 to see the readings. I have used VCC 5v for Opamp, ESP and ADS1115. I am using LM358 opamp for this. I want to measure -1V to 1V differential DC. can someone help what outputs I should expect for each voltages as I am not getting exact same voltages from ADS1115. I am also attaching the implemented circuit for reference here's the voltage at a few setpoints At 1.025V -> 0.610 V At 727 mV -> 0.430V At 627 mV -> 0.370V At 523 mV -> 0.307V At 424 mV -> 0.250V At 328 mV -> 0.193V At 223 mV -> 0.130V At 126 mV -> 0.070V
