Idle Vout of V+ at AD3

Hi team, Can you please check it? Recently I placed the order and checked V+ output noise of AD3. However, it is 120mV output offset during V- makes 19mV even though I calibrated newly. Is it the in range spec? I believe it is NOT normal. Too much high 120mV V+ for lab equipment. Thanks in advance, can you please update me?

Hi @plswelcomeroh The maximum leakage voltage when the V+ is shut down is 641mV and with 1k dummy load max is 67mV. The supply circuit's Schottky diode reverse current further reduces this voltage, depending on temperature. On a cold device I see 500mV and after it heats up only 50mV.
