Description

The PCM1720 is a complete low cost stereo audiodigital-to-analog converter (DAC), operating off of a256fS or 384fS system clock. The DAC contains a 3rd-order ∆ modulator, a digital interpolation filter, andan analog output amplifier. The PCM1720 can accept16-, 20-, or 24-bit input data in either normal or I2S
formats.

The digital filter performs an 8X interpolation func-tion and includes selectable features such as soft mute,digital attenuation and digital de-emphasis. ThePCM1720 can accept standard digital audio samplingfrequencies as well as one-half and double samplingfrequencies.

The PCM1720 is ideal for applications which combinecompressed audio and video data such as DVD, DVD-ROM, set-top boxes and MPEG sound cards.
