ELECTRICAL CHARACTERISTICS
Test Conditions
DCVDD = 1.8V, DBVDD = 3.3V, AVDD = HPVDD = 3.3V, SPKVDD = 5V, 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)
A1
A2
Maximum Full-Scale PGA
Input Signal Level
Note 1: This changes in
proportion to AVDD
(AVDD/3.3).
Note 2: When mixing input
PGA outputs and line
inputs the total signal
must not exceed 1Vrms
(0dBV).
Note 3: A 1.0Vrms
differential signal equates
to 0.5Vrms/-6dBV per
input.
Maximum Full-Scale Line
Input Signal Level
Note 1: This changes in
proportion to AVDD
(AVDD/3.3).
Note 2: When mixing line
inputs, input PGA outputs
and DAC outputs the total
signal must not exceed
1Vrms (0dBV).
Note 3: A 1.0Vrms
differential signal equates
to 0.5Vrms/-6dBV per
input.
