ASAHI KASEI
[AK5355]
AK5355
Low Power 16bit ∆Σ ADC
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 16-pin TSSOP package.
