ELECTRICAL CHARACTERISTICS
Test Conditions
DCVDD = 1.8V, HBVDD = MBVDD = I2CVDD = I2S1VDD = I2S2VDD = AVDD = HPVDD = 3.0V, SPKVDD = 5V,

PARAMETER
Analogue Input Pin Maximum Signal Levels (LIN1, LIN2, LIN3, LIN4, RIN1, RIN2, RIN3, RIN4)
Maximum Full-Scale PGA
Input Signal Level
Note 1: This changes in
proportion to AVDD. Full-
Scale level is typically
AVDD/3.3Vrms
Note 2: When mixing
input PGA outputs and
line inputs the total signal
must not exceed the
values shown here.
Maximum Full-Scale Line
Input Signal Level
Note 1: This changes in
proportion to AVDD. Full-
Scale level is typically
AVDD/3.3Vrms
Note 2: When mixing line
inputs, input PGA outputs
and DAC outputs the total
signal must not exceed
the values shown here.
