LMV932-N: LMV932MAX

Part Number: LMV932-N

The following problems occurred with the ”LMA932MAX” I purchased previously.

・The board output voltage was not the desired value.

The amplifier output was normal, but the voltage value became abnormal when it was passed through the final stage buffer.
 The voltage before and after the buffer should be approximately the same.
When measuring the input terminal of the buffer, the operation when the op amp is in negative feedback is.
   The virtual short is not established.
Please provide an analysis and answer regarding these problems.
