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 Out-
band 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, 44.1, 48kHz sampling
† Soft mute
† I/F format : MSB justified, LSB justified, IIS
† THD+N: -87dB
† DR: 92dB
† Master Clock: 256fs or 384fs
† Power supply: 4.5 to 5.5V
† Small Package: 24pin SSOP
† AK4319 Compatible

(Internal Pull-down pin)
2 DVDD
- Digital Power Supply
3 DVSS
- Digital Ground Pin
4 LRCK
I L/R Clock Pin
5 BICK
I Audio Serial Data Clock Pin
6 SDATA
I Audio Serial Data Input Pin
2's complement MSB-first data is input on this pin.
7 PD
I 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.
8 XTI
I Master Clock Input Pin
A crystal can be connected between this pin and XTO, or an external
CMOS clock can be input on XTI.
9 XTO
O Crystal Oscillator Output Pin
When an external clock is input, this pin should be left floating.
10 CLKO
O Clock Output Pin
The inverted XTI clock is output.
11 SMUTE
I Soft Mute Pin
(Internal Pull-down pin)
When this pin goes "H", soft mute cycle is initiated.
When returning "L", the output mute releases.
12 DEM0
