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 I
2
S. The system clock can be 256f
S
or
384f
S
. 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.

NOTES: (1) Dynamic performance specs are tested with external 20kHz low pass filter and THD-B specs are test with 30kHz LPF, 400Jz HPF, Average Mode,
Shibasoku #725 THD Meter. (2) RSTB pin, MD pin, MC pin, and ML pin include an internal pull-up resistor. (3) RSTB pin, MD pin, MC pin, and ML pin include
internal Schmitt trigger circuits. (4) ZERO pin is an open drain output. (5) Line output should be connected by a coupling capacitor. (6) Headphone output should
be connected by a coupling capacitor. (7) Supply current and power dissipation are measured at CLKO pin = no load, XTO pin = no load.
