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.
(1) V_RB, V_RM and V_RT are decoupled to AGND.
(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.
