AK5701
16-Bit ΔΣ Stereo ADC with PLL & MIC-AMP
GENERAL DESCRIPTION The AK5701 features a 16-bit stereo ADC. Input circuits include a Microphone-Amplifier and an ALC (Auto Level Control) circuit that is suitable for portable application with recording function. On-chip PLL supports base-band clock of mobile phone, therefore it is easy to connect with DSP. The AK5701 is available in a 24pin QFN, utilizing less board space than competitive offerings. FEATURES 1. Resolution: 16bits 2. Recording Function - 2 Stereo Input Selector - Full-differential or Single-ended Input - MIC Amplifier (+30dB/+15dB or 0dB) - Input Voltage: 1.8Vpp@VA=3.0V (= 0.6 x AVDD) - ADC Performance: S/(N+D): 78dB, DR, S/N: 89dB@MGAIN=0dB S/(N+D): 77dB, DR, S/N: 87dB@MGAIN=+15dB S/(N+D): 72dB, DR, S/N: 77dB@MGAIN=+30dB - Digital HPF for DC-offset cancellation (fc=3.4Hz@fs=44.1kHz) - Digital ALC (Automatic Level Control) (+36dB 54dB, 0.375dB Step, Mute) 3. Sampling Rate: - PLL Slave Mode (EXLRCK pin): 7.35kHz 48kHz - PLL Slave Mode (EXBCLK pin): 7.35kHz 48kHz - PLL Slave Mode (MCKI pin): 8kHz, 11.025kHz, 12kHz, 16kHz, 22.05kHz, 24kHz, 32kHz, 44.1kHz, 48kHz - PLL Master Mode: 8kHz, 11.025kHz, 12kHz, 16kHz, 22.05kHz, 24kHz, 32kHz, 44.1kHz, 48kHz - EXT Slave Mode: 7.35kHz 48kHz (256fs), 7.35kHz 26kHz (512fs), 7.35kHz 13kHz (1024fs) 4. PLL Input Clock: - MCKI pin: 27MHz, 26MHz, 24MHz, 19.2MHz, 13.5MHz, 13MHz, 12.288MHz, 12MHz, 11.2896MHz - EXLRCK pin: 1fs - EXBCLK pin: 32fs/64fs 5. Master/Slave mod……
