BIAS Capacitor
BIAS is the output of the internally-generated VCC/2 bias
voltage. The BIAS bypass capacitor, CBIAS, improves the
power-supply rejection ratio by reducing power supply
and other noise sources at the common-mode bias node.
CBIAS also generates the clickless/popless startup DC
bias waveform for the speaker amplifiers. Bypass BIAS
with a 1F capacitor to GND. Larger CBIAS values
improve PSRR but slow down tON time. Do not connect
external loads to BIAS.
Supply Bypassing
Proper power-supply bypassing ensures low-noise,
low-distortion performance. Connect a 1F ceramic
capacitor from VCC to GND. Add additional bulk
capacitance as required by the application. Connect
the bypass capacitor as close to the device as possible.
Layout and Grounding
Proper PC board layout and grounding is essential for
optimizing performance. Use large traces for the
power-supply inputs and amplifier outputs to minimize
losses due to parasitic trace resistance. Large traces
also aid in moving heat away from the package. Proper
grounding improves audio performance and prevents
digital switching noise from coupling into the audio signal.
The MAX9716/MAX9717 TDFN and MAX packages
feature exposed thermal pads on their undersides. This
pad lowers the thermal resistance of the package by
providing a direct-heat conduction path from the die to
the printed circuit board. Connect the exposed pad to
the ground plane using multiple vias, if required.
