Datasheet

1. General Description

The ALC5624 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 DAC for playback, and a

stereo ADC for recording via the I2S/PCM interface.

Stereo audio functions are supported via the I2S/PCM configurable interface. To reduce component count,

the device can connect directly to:

• MONO or stereo differential analog inputs

• Stereo headphone

• Single-ended or BTL MONO output

• 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 1.7 Watt 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, and enriches the sound experience.

ALC5624 Digital power operates at supply voltages from 1.8V to 3.6V. Analog power operates from

2.3V to 3.6V, and Speaker power 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 ALC5624 is available in a 7x7mm ‘Green’ QFN package, making it ideal for use in handheld

portable systems.
