ASAHI KASEI

The AK5354 is a low voltage 20bit A/D converter for digital audio system. The AK5354 also includes

Analog input PGA, therefore is suitable for microphone application and etc. As digital power supply of the

AK5354 corresponds to 1.8V, the interface with microprocessor can operate at low voltage. Analog

signal input of the AK5354 is single-ended, therefore, any external filters are not required. As the

package is 16pin TSSOP, the AK5354 is a suitable for minimizing system.
