ES4810SAA

Digital Audio Processor

Product Brief

DESCRIPTION

The ES4810SAA Digital Audio Processor (DAP™3) is an

SOC chip designed for automotive audio 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 Low-profile Quad Flat Pack (LQFP) package with lead-

free leads. The silicon is qualified for an extended

temperature range of –40 to 85

°C for automotive

applications.
