Description

The ALC5621 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.

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.

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 Headphone Output

• Single-ended stereo configurable to AUXOUT or BTL MONO_OUT

• MONO or Stereo Bridge-Tied Load (BTL) speaker

Pinouts:

System Applications:

1. Tablet PC system/Ultra-Mobile PC (UMPC)

2. Personal Digital Assistants (PDA) or PDA Phone

3. Multimedia Phone Applications

4. Portable Navigation Device (PND)

5. Bluetooth Headphone
