Overview
ASAHI KASEI [AK4324] AK4324 96kHz Sampling 24Bit ∆Σ DAC General Description The AK4324 is a high performance 1bit stereo DAC for the 96kHz sampling mode of DAT,DVD including a 24bit digital filter.
A 1bit DAC can achieve monotonicity and low distortion with no adjustment and is superior to traditional R-2R ladder based DACs.
In the AK4324, the analog outputs are filtered in the analog domain by switched-capacitor filter(SCF) with high tolerance to clock jitter.
The digital I/F can www.

The AK4324 should always be reset upon power-up.
Audio Serial Data Clock Pin 64fs clock is recommended to be input on this pin.
Audio Serial Data Input Pin 2's complement MSB-first data is input on this pin.
L/R Clock Pin Soft Mute Pin When this pin goes "H", soft mute cycle is initiated.
When returning "L", the output mute releases.
