描述 Description

The ALC5634 is a highly-integrated I2S/PCM interface audio DAC with multiple input/output ports, and is designed for multimedia handheld devices. It provides a Stereo Hi-Fi DAC for playback via the I2S/PCM interface.To reduce component count, the ALC5634 can connect to: LINEIN_L/R stereo Single-Ended analog inputs that can be configured to Differential analog input AUXIN_L/R stereo Single-Ended analog inputs that can be configured to Differential analog input LINE3_L/R stereo Single-Ended analog inputs Single-Ended stereo Headphone Output STEREO Bridge-Tied Load (BTL) LINE_OUT 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.The ALC5634 AVDD operates at supply voltages from 2.3V to 3.6V. DCVDD and DBVDD operate from 1.8 to 3.6V. 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 ALC5634 is available in a 5x5mm ‘Green’ QFN-32 package, making it ideal for use in handheld portable systems.
