Supply Bypassing/Layout
Proper power-supply bypassing ensures low distortion
operation. For optimum performance, bypass V
DD to
PGND with a 0.1µF capacitor as close to each V DD pin
as possible. A low-impedance, high-current power-sup-
ply connection to V DD is assumed. Additional bulk
capacitance should be added as required depending on
the application and power-supply characteristics. AGND
and PGND should be star connected to system ground.
Refer to the MAX9704 Evaluation Kit for layout guidance.
