DESCRIPTION
PCM1719 is a plete, low cost stereo audio digitalto-analog converter (DAC) including a digital interpolation 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 256f S or 384f S. PCM1719 is fabricated on a highly advanced 0.6µs CMOS process, which delivers high performance at very low power dissipation.
