DESCRIPTION

The PCM1717 is a complete low cost stereo, audio
digital-to-analog converter, including digital interpo­lation filter, 3rd-order delta-sigma DAC, and analog
output amplifiers. PCM1717 is fabricated on a highly
advanced 0.6µ CMOS process. PCM1717 accepts
16- or 18-bit normal input data format, or 16- or
18-bit I2S data format.

The digital filter performs an 8X interpolation func­tion, as well as special functions such as soft mute,
digital attenuation, and digital de-emphasis. The digi­tal filter features –35dB stop band attenuation and
±0.17dB ripple in the pass band.

PCM1717 is suitable for a wide variety of cost-sensitive
consumer applications where good performance is re­quired. Its low cost, small size, and single +5V power
supply make it ideal for automotive CD players, book­shelf CD players, BS tuners, keyboards, MPEG audio,
MIDI applications, set-top boxes, CD-ROM drives,
CD-Interactive, and CD-Karaoke systems.

ELECTROSTATIC
DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.

ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
