AK4480EF

ADCs/DACs - Special Purpose Overview

The AK4480EF is a high-performance 32-bit digital-to-analog converter (DAC) designed for Blu-ray Disc and SACD systems. It features an internal 32-bit digital filter with selectable ripple, delay, and roll-off characteristics to optimize sound quality. The device supports sampling rates from 30kHz to 216kHz and accepts PCM and DSD data inputs. Key electrical specifications include a dynamic range of 114dB and THD+N of -100dB. It utilizes full differential SCF outputs to eliminate AC coupling capacitors and reduce clock jitter sensitivity. The component operates on a 4.75V to 5.25V power supply and is housed in a 30-pin VSOP package.
