Dear Sirs,
My customer meet strange issue of LM2904 abnormal output voltage.
if customer touch the PCB or IC body, bend PCB a little, then the LM2904 output voltage will change.
Customer gain is set to 151, and the input signal is around 10mV, input voltage is +5V and -5V.
Customer also use typical non-inverting connection for testing, but issue still same.
Please give me some idea if there is anything need to pay attention or any other solutions that can help customer.
Thanks.
