TL082: TL082

Part Number: TL082
Other Parts Discussed in Thread: TLV272, LM358,

Dear sir

We are using Opamp TLO82C in our design as difference amplifier having 0.5 gain. The op amp is not working properly and not giving the difference of signal.

 For example for positive signal of 4.24V and negative signal signal of 2.5V, It should give 0.87, but the reading is 1.4V.

If we reduce positive signal, the output is unchanged.

 But when we use LM358 or TLV272 in the same circuit, the results are proper.

 Please guide us, whether TLO82 is improper for this circuit, or any other issue.
