ASAHI KASEI [AK5356] AK5356 Low Power 20-Bit ADC with MIC-Amp & PGA GENERAL DESCRIPTION The AK5356 is a low voltage 20bit A/D converter for digital audio system. The AK5356 also includes microphone amplifier and analog input PGA, making it suitable for microphone applications or low-input signal levels. As digital power supply of the AK5356 corresponds to 1.8V, the interface with microprocessor can operate at low voltage. The AK5356 is housed in a space-saving 28-pin QFN package. FEATURES 1.
