[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. FEATURES Recording Function - 4-Channel ADC - Full-differential or Single-ended Input - Microphone Amplifier (+36dB/+30dB/+24dB/+18dB/+15dB/+12dB/+8dB/0dB) - Input Voltage: 1.8Vpp@AVDD=3.0V (= 0.
