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 鈥?2dB

stop band attenuation and

鹵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.
