AK4558 Datasheet 108db 216khz 32-bit Codec

Manufacturer: AKM (Asahi Kasei Microdevices)

Overview: [AK4558] AK4558 108dB 216kHz 32Bit  CODEC with PLL 1. General.

General Description

The AK4558 is a low voltage 32bit 216kHz CODEC for high performance battery powered digital audio subsystems.

An internal circuit includes newly developed 32-bit Digital Filter achieving short group delay and high quality sound.

In addition, “OSR-Doubler” technology is newly adopted, making the AK4558 capable of supporting wide range signals and achieving low out-of-band noise while realizing low power consumption.
