ENGLISH DATASHEETS for Realtek ALC5622
Realtek ALC5622 (sound chip)
Release: 1.2 from 2009-07-21

Designed only for Realtek ALC5622-GR ALC5622-GRT
The ALC5622 is a highly-integrated I2S/PCM interface audio codec with multiple input/output ports and is designed for mobile computing and communications. It provides a Stereo Hi-Fi DAC for playback and Stereo ADC for recording via the I2S/PCM interface.

To reduce component count, the device can connect directly to:
• MONO or stereo differential analog inputs
• LINE_IN stereo single-ended analog inputs
• AUX_IN single-ended analog inputs
• Stereo LINE_Out Output
• Single-ended stereo configurable to AUXOUT or BTL MONO_OUT
• MONO or Stereo Bridge-Tied Load (BTL) speaker

Multiple analog input and output pins are provided for seamless integration with analog connected wireless communication devices. Differential input/output connections efficiently reduce noise interference, providing better sound quality. Class-AB or Class-D amplifiers are easily swapped via simple register configuration, and the 2.6-Watt Mono speaker removes the need for an additional amplifier, further cutting both cost and required board area. Additionally, a flexible hardware 5-band equalizer with configurable gain, bandwidth, and center frequency, enriches the sound experience.

The ALC5622 AVDD operates at supply voltages from 2.3V to 3.6V. DVDD operates from 1.71V to 3.6V, and SPKVDD operates from 2.3V to 5V. To extend battery life, each section of the device can be powered down individually under software control. Leakage current in maximum power saving state is less than 10μA.

The ALC5622 is available in a 5x5mm ‘Green’ QFN-32 package, making it ideal for use in handheld portable systems.
