Low-Power, Stereo Audio Codec
with FlexSound Technology
Use the attenuator at the EQ’s input to avoid clipping
the signal. The attenuator can be programmed for fixed
attenuation or dynamic attenuation based on signal level.
If the dynamic EQ clip detection is enabled, the signal
level from the EQ is fed back to the attenuator circuit to
determine the amount of gain reduction necessary to
avoid clipping.
The MAX98089 EV kit software includes a graphical inter-
face for generating the EQ coefficients. The coefficients
are sample rate dependent and stored in registers 0x52
through 0xB5.

DAI1/DAI2 EQ Clip Detection
Automatically controls the EQ attenuator to prevent clipping in the EQ.

DVEQ1/DVEQ2
DAI1/DAI2 EQ Attenuator
Provides attenuation to prevent clipping in the EQ when full-scale signals are
boosted. DVEQ1/DVEQ2 operates only when EQ1EN/EQ2EN = 1 and EQCLP1/EQ-
CLP2 = 1.
