I am trying to compare two low noise mic pres for the lowest noise, and I am looking at the
TI1012 and MAX9814
MAX9814: ♦ Low Input-Referred Noise Density of 30nV/√Hz TI1012: Output Voltage Noise (A-Weighted): −89 dBV
I thought I could get some insight from simply converting the 30nV into dBV, but ~-150dBV doesn't make sense. I would expect it to be very similar to the -89dBV. I believe my lack of understanding is in the density portion (√Hz) and how it is calculated.
