Overview
[AK4482] AK4482 111dB 192kHz 24-Bit 2ch ΔΣ DAC GENERAL DESCRIPTION The AK4482 is a cost-effective 24-bit DAC for digital audio equipments.
The modulator uses AKM's multi-bit architecture, delivering wide dynamic range.
The AK4482 has fully differential switched-cap filter outputs, removing the need for AC coupling capacitors and increasing performance for systems with excessive clock jitter.
The AK4482 support up to 216kHz sampling rate, ideal for BD and AC-3 amplifier systems.
It is housed in a space saving 16pin TSSOP package.
