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.
