AKM AK4392EQ

Overview

The AK4390 is a high performance stereo DAC capable of sampling up to 216kHz including a 32-bit digital filter. The modulator uses AKM's multi-bit architecture, delivering wide dynamic range while preserving linearity for improved THD+N performance. The AK4390 has fully differential switched-cap filter outputs, removing the need for AC coupling capacitors and increasing performance for systems with excessive clock jitter. The AK4390 accepts 192kHz PCM data, ideal for a wide range of applications including DVD-Audio, high end sound cards, digital audio Firewire and USB interface boxes, and digital mixers.
