DESCRIPTION
The PCM1715 is a low cost, dual voltage output
CMOS digital-to-analog converter. Incorporated into
the PCM1715 is a unique multi-level 4th-order delta-
sigma architecture that eliminates influence from in-
put clock jitter and RF interferance resulting in truly
superior performance.
The PCM1715 has individual channel attenuator and
analog output mode select function which is suitable
for CD-ROM application.
The on-chip digital filter of the PCM1715 has –62dB
stop band attenuation and ±0.008dB ripple in the pass
band.
The PCM1715 can be used in a wide variety of
consumer audio applications. Its low cost, small size,
and single +5V operation make it ideal for portable,
automotive, CD players, CD-I, CD-ROM, VIDEO-
CD, tuners, music instruments, and other digital audio
applications.
