PCB Layout and Bypassing
Proper layout and grounding are essential for optimum
performance. Use large traces for the power-supply
inputs and amplifier outputs to minimize losses due to
parasitic trace resistance. Proper grounding improves
audio performance, minimizes crosstalk between chan-
nels, and prevents any switching noise from coupling
into the audio signal. Connect AGND, DGND, CPGND,
and PGND together at a single point on the PCB using
the star grounding technique. Route DGND, CPGND,
and all traces that carry switching transients or digital
signals separately from AGND and the analog audio
signal paths. Ground all components associated with
the charge pump to CPGND (CPVSS bypassing and
CPVDD bypassing). Connect all digital I/O termination
to DGND including DVDD and DVDDS2 bypassing.
Bypass REF and MICBIAS to AGND.
Connect PVSS and SVSS together at the device and
place the charge-pump hold capacitor (C2) as close to
SVSS as possible and ground to CPGND. Bypass
CPVDD with a 1F capacitor to CPGND and place the
bypass capacitor as close to the device as possible.
The MAX9856 thin QFN package features an exposed
thermal pad on its underside. This pad lowers the pack-
age’s thermal resistance by providing a direct heat
conduction path from the die to the PCB. Connect the
exposed thermal pad to AGND.
An evaluation kit (EV Kit) is available to provide an
example layout for the MAX9856. The EV Kit allows
quick setup of the MAX9856 and includes easy-to-use
software allowing all internal registers to be controlled.
