AD1868  
TIMING  
AD1868 drops. T his extends the usable battery life. Finally, as  
the battery supply voltage drops, the bias voltages and signal  
swings also drop, preventing signal clipping and abrupt degra-  
dation of distortion. Figure 3 illustrates that T HD+N perfor-  
mance of the AD1868 remains constant through a wide range  
of supply voltages.  
Figure 10 illustrates the specific timing requirements that must  
be met in order for the data transfer to be accomplished prop-  
erly. T he input pins of the AD1868 are T T L and 5 V CMOS  
compatible.  
T he maximum clock rate of the AD1868 is specified to be at  
least 13.5 MHz. T his clock rate allows data transfer rates of 2×,  
4×, 8×, and 16× FS (where FS equals 44.1 kHz). T he applica-  
tions section of this data sheet contains additional guidelines for  
using the AD1868.  
Automotive equipment rely on components which are able to  
consistently perform in a wide range of temperatures. In addi-  
tion, due to the limited space available in automotive applica-  
tions, small size is essential. T he AD1868 is able to satisfy both  
of these requirements. T he device has guaranteed specified per-  
formance between 0°C and +70°C, and the 16-pin DIP or 16-  
pin SOIC package is particularly attractive where overall size is  
important.

LATCH  
Since the AD1868 provides dc bias voltages, the entire signal  
chain can be dc-coupled. T his eliminate ac-coupling capacitors  
from the signal path, improving low frequency performance and  
lowering system cost and size.

In summary, the AD1868 is an excellent choice for battery op-  
erated portable or automotive digital audio systems. In the fol-  
lowing sections, some examples of high performance audio  
applications featuring the AD1868 are described.

Figure 11 illustrates an 18-bit CD player design incorporating  
an AD1868 DAC, a Sony CXD2550P digital filter and 2-pole  
antialias filters. T his high performance, single supply design op-  
erates at 8× FS and is suitable for portable and automotive ap-  
plications. In this design, the CXD2550P filter transmits left  
and right channel digital data to the AD1868. T he left and  
right latch signals, LL and LR, are both provided by the word  
clock signal (LRCKO) of the digital filter. T he digital data is  
converted to low distortion output voltages by the output  
amplifiers on the AD1868. Also, no deglitching circuitry or  
external adjustments are required. Bypass capacitors, noise  
reduction capacitors and the antialias filter details are omitted  
for clarity.  
T he AD1868 is a high performance audio DAC specifically de-  
signed for portable and automotive digital audio applications.  
T hese market segments have technical requirements fundamen-  
tally different than those found in the high-end or home-use  
market segments. Portable equipment must rely on components  
which require low amounts of power to offer reasonable playing  
times. Also, battery voltages drop as the end of the discharge  
cycle is approached. T he AD1868’s ability to operate from a  
single +5 V supply makes it a good choice for battery-operated  
gear. As the battery voltage drops, the power dissipation of the
