I'm trying to buffer a 0.450V (from a voltage divider) with the LT1674 opamp. However, I'm seeing 0.470V at the output of the opamp. As far as I can tell, I'm within the operating specs of the opamp:
vin range: 0.2V to 36V
vsupply range: 2.2 to 36V
I tried putting a 1.6k resistor from output to Vin- so input resistances are the same, but didn't help.
What's gone wrong? This is quite perplexing.
Here's the circuit I built on the bread board, with actual measured voltages:
vin range: 0.2V to 36V
vsupply range: 2.2 to 36V
