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 correspond to TTL levels.1 s- G" q \7 @: o* Z0 ?
