Product Summary

The PCM1720E 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 3rd-order △Σ modulator, a digital interpolation filter, and an analog output amplifier. The PCM1720E can accept 16-, 20-, or 24-bit input data in either normal or I2S formats. The PCM1720E is ideal for applications which combine compressed audio and video data such as DVD, DVD-ROM, set-top boxes and MPEG sound cards.
