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

An application note is available which describes the design and the realization of a demonstration board

that uses TDA8764HL in an application environment.

(1) VRB, VRM and VRT are decoupled to AGND.

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