Part Number: OPA1662 Other Parts Discussed in Thread: OPA1622 Tool/software: Hello,
I am working with the OPA1662 and would like to clarify something in the datasheet. When one looks at the short circuit current of +/- 50 mA @ +/-15V, the note "One…
Part Number: OPA1662 Other Parts Discussed in Thread: OPA1652 Tool/software: Hi,
I designed and built this circuit as a differential ADC input stage.
If I select the x4 gain or x8 gain (changing R3 value) the outputs are completly unbalanced.
If…
