Spec as below:
1. meet AEC-Q100 (base on cost issue, Q100 also not require need)
2. Operator Voltage : 3VDCmin
3. noise < 40nV/rtHz @1kHz (Relatively LM2904, currently Noise Floor need improve 18dBA)
4. PSRR >> 65dB
5. PSR << -95dBV(A)
if OK, could you help provide formula unit about nV/rtHz translate to dB ?
