Product Summary

The PCM1728E 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 DS modulator, a digital interpolation filter, and an analog output amplifier. The PCM1728E accepts 16-bit input data in either normal or I2S formats. The digital filter performs an 8X interpolation function and includes de-emphasis at 44.1kHz. The device can accept digital audio sampling frequencies from 16kHz to 96kHz, always at 8X oversampling. The PCM1728E is ideal for low-cost, CD-quality consumer audio applications.
