Notes:
1.
The digital output signal level is measured in dBFS, where 0dBFS is a signal level equal to the full-scale range (FSR) of the PDM output.
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.
Test Conditions
DBVDD1 = DBVDD2 = DBVDD3 = DBVDD4 = CPVDD1 = AVDD = LDOVDD = 1.8V, CPVDD2 = 1.2V,
DCVDD = FLLVDD = 1.2V (powered from LDO1), MICVDD = 2.5V (powered from LDO2), SPKVDDL = SPKVDDR = 4.2V,
TA = +25ºC, 1kHz sinusoid signal, fs = 48kHz, PGA gain = 0dB, 24-bit audio data unless otherwise stated.
