com ASAHI KASEI [AK4319A] AK4319A 18Bit SCF DAC General Description The AK4319A is a high performance 1bit stereo DAC for digital audio systems.
A 1bit DAC can achieve monotonicity and low distortion with no adjustment.
On chip SCF filter makes the device less affected to the clock jitter and also suppresses the undesirable radio emission noise.
The device equips differentially configurated output pins, but either of the pins can be used as single-end.
The AK4319A achieves lower Outband noise characteristic and it is suitable for digital broadcasting tuner and other digital audio applications.
Features † Sampling Rate Ranging from 8kHz to 54kHz † 128 times Oversampling † 18bit 8 times Digital Filter † 2nd order SCF with High Tolerance to Clock Jitter † Differential outputs(Single-end use is available) † Digital de-emphasis for 32, 44.

Power-Down Mode Pin When at "L", the AK4319A is in power-down mode and is held in reset.
The AK4319A should always be reset upon power-up.
Master Clock Input Pin A crystal can be connected between this pin and XTO, or an external CMOS clock can be input on XTI.
