Description

The AK4394VF-E2 model is a stereo DAC (digital-to-analog converter) that belongs to the IC Chips category of electronics components. It is a high-performance device with some advanced features that make it suitable for high-end audio applications. The AK4394 uses a multi-bit system for DS modulator which widens the dynamic range of the sound, while maintaining low distortion levels. It features a 24-bit digital filter and a 128x oversampling. The analog outputs are filtered with a switched-capacitor filter (SCF) that has high tolerance to clock jitter. This DAC supports digital de-emphasis for 32, 44.1, 48 & 96kHz sampling and has a soft mute feature to prevent pops and clicks. The AK4394VF-E2 is housed in a small 28-pin VSOP package and has TTL level digital I/F support.
