The coefficients b0, b1, b2, a1, and a2 are sample
rate dependent and stored in registers 0xB4 through
0xC7. Store b0, b1, and b2 as positive numbers. Store
a1 and a2 as negated two’s complement numbers.
Separate filters can be stored for the DAI1 and DAI2
playback paths.
The MAX98089 EV kit software includes a graphic interface
for generating the user-programmable biquad coefficients.
Note: Only change the excursion limiter settings when
the signal path is disabled to prevent undesired artifacts.
