Low Power Stereo Audio CODEC

With Headphone Amplifier

Revision 1.0 April 2011

ES8323

GENERAL DESCRIPTION

FEATURES

ES8323 is a high performance, low

power and low cost audio CODEC.

It consists of 2-ch ADC, 2-ch DAC,

microphone amplifier, headphone

amplifier, digital sound effects, and

analog mixing and gain functions.

The device uses advanced multi-bit

delta-sigma modulation technique

to convert data between digital and

analog. The multi-bit delta-sigma

modulators make the device with

low sensitivity to clock jitter and low

out of band noise.

ADC

• 24-bit, 8 kHz to 96 kHz sampling frequency

• 95 dB dynamic range, 95 dB signal to noise ratio,

-85 dB THD+N

• Stereo or mono microphone interface with

microphone amplifier

• Auto level control and noise gate

• 2-to-1 analog input selection

• Various analog input mixing and gains

DAC

• 24-bit, 8 kHz to 96 kHz sampling frequency

• 96 dB dynamic range, 96 dB signal to noise ratio,

-83 dB THD+N

• 40 mW headphone amplifier, pop noise free,

capless option

• Stereo enhancement

• Bass and Treble

• Various analog output mixing and gains

Low Power

• 1.8V to 3.3V operation

• 7 mW playback; 16 mW playback and record

System

• I

C or SPI uC interface

• 256Fs, 384Fs, USB 12 MHz or 24 MHz

• Master or slave serial port

• I

S, Left Justified, DSP/PCM Mode

APPLICATIONS

ORDERING INFORMATION
