Test Conditions
DCVDD = 1.8V, DBVDD = 3.3V, AVDD = 3.3V, T
PGA gain = 0dB, 24-bit audio data unless otherwise stated.
PARAMETER
Analogue Input Pin Maximum Signal Levels (LIN1, LIN2, LIN3, LIN4, RIN1, RIN2, RIN3, RIN4)
Maximum Full-Scale PGA
Input Signal Level
Note 1; Note 2; Note 3
Maximum Full-Scale Line
Input Signal Level
Note 1; Note 2; Note 3
Maximum full scale signal changes in proportion to AVDD (AVDD/3.3).
When mixing input PGA outputs and line inputs, the total signal must not exceed 1Vrms (0dBV).
A 1.0Vrms differential signal equates to 0.5Vrms/-6dBV per input.
