ES4810
Digital Audio Processor
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.
