[AK5702] AK5702 4-Channel ADC with PLL & MIC-AMP GENERAL DESCRIPTION The AK5702 features a 4-channel ADC. Input circuits include a Microphone-Amplifier with programmable gain and an ALC (Auto Level Control) circuit, making it ideal for consumer microphone array applications. On-chip PLL and TDM audio format makes it easy to connect with DSP. The AK5702 has a software compatibility with stereo version, AK5701. FEATURES 1. Recording Function - 4-Channel ADC - 3:1 Stereo Input Selector - Full-differential or Single-ended Input - MIC Amplifier (+36dB/+30dB/+15dB/0dB) - Input Voltage: 1.8Vpp@AVDD=3.0V (= 0.6 x AVDD) - ADC Performance: S/(N+D): 83dB, DR, S/N: 89dB@MGAIN=0dB S/(N+D): 83dB, DR, S/N: 87dB@MGAIN=+15dB - Digital HPF for DC-offset cancellation (fc=3.4Hz@fs=44.
