Overview
ASAHI KASEI [AK5700] 16-Bit ΔΣ Mono ADC with PLL & MIC-AMP GENERAL DESCRIPTION The AK5700 features a 16-bit mono 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 AK5700 is available in a 24pin QFN, utilizing less board space than competitive offerings.
