Description

The PCM1744 is a complete low cost stereo audio digital-to-analog converter (DAC), operating off of a 256fS or 384fS system clock. The DAC contains a 3rdorder modulator, a digital interpolation filter, and an analog output amplifier. The PCM1744 accepts 24-bit input data in a I2S format.

The digital filter PCM1744 performs an 8x interpolation function and includes de-emphasis at 44.1kHz. The PCM1744 can accept digital audio sampling frequencies from 16kHz to 96kHz, always at 8X oversampling.

The PCM1744 is ideal for low-cost, CD-quality consumer audio applications.
