Product Brief

DESCRIPTION

The ES4810 Digital Audio Processor (DAP™3) is an SOC

chip designed for Audio Boom-Box and Mini-Combo

applications. It integrates a servo controller, RF amplifier,

servo DSP, MP3 and WMA decoders, USB 2.0 Driver, 2

channels audio DAC, 2 channels of audio ADC for

Karaoke, SD/MS/MMC card reader and MP3 encoder.

The ES4810 has the largest feature set and is the most

highly integrated and cost-effective solution currently

available.

The ES4810 provides auxiliary control pins for AM/FM

tuner control, LCD driver and system management. The

ES4810’s internal RISC processor can be used in place of

a microcontroller to provide all system controls and user

interface.

The ES4810 digital audio processor is available in a 208-

pin Plastic Quad Flat Pack (PQFP) device package.
