Fig.14 Application diagram (LQFP32).

The analog and digital supplies should be separated and well decoupled.

An application note is available and describes the design and the realization of a demoboard that uses TDA8764AHL with an

application environment.

(2) Decoupling capacitor for supplies must be placed close to the device.

(3) This resistor is mandatory (33

Ω is its minimum value) and must be near the clock source.
