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 performance at very low power dissipation.
PCM1719 is ideal for applications which require headphone drivers such as CD-ROM drives, digital audio workstations, portable CD players, and digital musical instruments.
