ELECTRICAL CHARACTERISTICS
Test Conditions
The following electrical characteristics are valid across the full range of recommended operating conditions.
PARAMETER

MIN
TYP
MAX
UNIT
Digital Microphone Input Signal Level (DMICDAT1, DMICDAT2)
Full-scale input signal level
(0dBFS signal to digital core)
0dB gain
-6
dBFS
Note:
The digital microphone input signal level is measured in dBFS, where 0dBFS is a signal level equal to the full-scale range (FSR) of the PDM
input. The FSR is defined as the amplitude of a 1kHz sine wave whose positive and negative peaks are represented by the maximum and
minimum digital codes respectively - this is the largest 1kHz sine wave that will fit in the digital output range without clipping.
