PCM1723 DIGITAL-TO-ANALOG CONVERTER

The PCM1723 is a complete, low-cost, stereo audio digital-to-analog converter (DAC) with a phase-locked loop (PLL) circuit included. The PLL derives either a 256fS or 384fS system clock from an external 27MHz reference frequency. The DAC contains a 3rd-order delta-sigma (∆Σ) modulator, a digital interpolation filter, and an analog output amplifier. The PCM17.
