Overview
[AK5703] AK5703 4-Channel 24-bit ADC with PLL & MIC-AMP GENERAL DESCRIPTION The AK5703 is a 4-channel 24-bit A/D converter with programmable microphone amplifiers and ALC (Automatic Level Control) circuit.
It is designed for consumer microphone array applications.
An integrated PLL operates from a wide variety of clocks, enabling high design flexibility.
Microphone power outputs are included for biasing external microphones.
Wide dynamic range is achieved, at 83dB with a microphone gain setting of +30dB.
The AK5703 is packaged in a space-saving 28-pin QFN package.
