Realtek PDF datasheets for ALC5620

The ALC5620 is a highly-integrated dual I2S/PCM interface audio codec with multiple input/output ports and is designed for mobile computing and communications. It provides a dual-channel Hi-Fi codec for playback, and dual-channel ADC for recording via an I2S interface. In addition, an Independent Voice DAC is provided with PCM interface for Bluetooth applications.

Both Stereo audio and voice 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-end 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 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.

The ALC5620 operates at supply voltages from 1.8 to 5 Volts. 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 ALC5620 is available in a 7x7mm ‘Green’ QFN package, making it ideal for use in handheld portable systems.
