|I am using an AD620 to convert a differential signal to single ended,|
with a gain of 1, as per attached schematic. My input is a 250 mVpp sine
wave of frequencies 0.1 Hz to 10 MHz, with no DC offset voltage.
|The output from the AD620 has a large DC offset on it of ~10V. The|
reference pin is tied to ground. There is no RF present, so I don't think
that the RF Interference section of the datasheet applies. There are no
offsets present when no input voltage is applied, of course.
|The datasheet doesn't mention any way to null any output offset|
voltage. Could you advise whether I'm doing something wrong, or if there
is a way to reduce the output offset voltage.
