Our customer has question about OPA2348.
I attach the circuit below with simplified.
Two OPA2348 are tested in same circuit.
Device A : 100mV at Probe_X and 100mV at Probe_Y.
Device B : Nearly 0V in both Probe point.
OPA2348 offers voltage output swing from fail in electrical characteristics.
(25mV when RL=100K, A >94dB and 125mV when RL=5K, A > 90dB)
Should this voltage appear at output when the input is not applied?
In this time, Device A and B show different result.
Could it be possible result?
The customer uses OPA2348 for current sensing, so they want to avoid such variation because it leads to measurement error.
