The ALC5611 is a highly-integrated AC'97 interface audio codec with multiple input/output ports and a 4-wire touch panel controller.
The ALC5611 is designed for mobile computing and communications.
Stereo audio is supported via the AC'97 interface. To reduce component count, the device can connect directly to:
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 ALC5611 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 10uA.
The ALC5611 is available in a 7x7mm ‘Green’ QFN package, making it ideal for use in handheld portable systems.
