DESCRIPTION
PCM1719 is a complete, low cost stereo audio digital-
to-analog converter (DAC) including a digital interpo-
lation filter, 3rd-order delta-sigma DAC, an analog
low-pass filter and output amplifier. PCM1719 also
has an on-chip stereo headphone amplifier.
PCM1719 can accept either 16-, or 18-bit input data.
The audio data input format can be either MSB-first,
right-justified or I2S. The system clock can be 256fS or
384fS. PCM1719 is fabricated on a highly advanced
0.6µs CMOS process, which delivers high perfor-
mance at very low power dissipation.
PCM1719 is ideal for applications which require head-
phone drivers such as CD-ROM drives, digital audio
workstations, portable CD players, and digital musical
instruments.
