FEATURES
The AK5355 is a low voltage 16bit A/D converter for digital audio systems. The AK5355 also includes an Input Gain Amplifier, making it suitable for microphone applications or low-input signal levels. The analog signal input of the AK5355 is single-ended, eliminating the need for external filters. The AK5355 is housed in a space-saving 16pin TSSOP or 20pin QFN package.
