ADAV4601 is an audio processor for advanced TV, which provides 28-bit audio processing flow, supports audio/video synchronization, integrates high performance 24-bit ADC and DAC, supports headphone output and high performance PWM digital output
The ADAV4601 is a fully programmable 28‑bit audio processor designed for advanced TV (ATV) sound enhancement. It includes a high‑performance 24‑bit ADC and DAC, adjustable digital delay for audio/video sync up to 200 ms, headphone output with integrated amplifiers, PWM digital outputs, multichannel digital I²S I/O, and a 6‑channel sample‑rate converter supporting 5 kHz‑50 kHz input rates.
The document provides a functional block diagram, detailed pin configuration, timing specifications, absolute maximum ratings, thermal information, and a full set of performance parameters such as dynamic range, THD+N, power‑supply rejection, and output impedance. An ordering guide and package dimensions for the 80‑lead LQFP are also included.
