AK4420 Datasheet 192kHz 24-Bit Stereo DAC

Manufacturer: AKM (Asahi Kasei Microdevices)

General Description

The AK4420 is a 5V 24-bit stereo DAC with an integrated 2Vrms output buffer.

A charge pump in the buffer develops an internal negative power supply rail that enables a ground-referenced 2Vrms output.

Using AKM’s multi bit modulator architecture, the AK4420 delivers a wide dynamic range while preserving linearity for improved THD+N performance.
