Texas Instruments' PCM5122/42 devices are a family of monolithic CMOS integrated circuits that include a stereo digital-to-analog converter and additional support circuitry in a small TSSOP package. The PCM5122/42 uses the latest generation of TI’s advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter.

The PCM5122/42 provides 2.1 VRMS ground-centered outputs, allowing designers to eliminate DC blocking capacitors on the output, as well as external muting circuits traditionally associated with single supply line drivers.

Members of the PCM5122 family integrate preset audio processing functions with programmable coefficients, allowing developers to change the characteristics of the interpolation filter, speaker EQ, dynamic range controls, and average volume control in their products.

Members of the PCM5142 family integrate a fully-programmable miniDSP core, allowing developers to integrate filters, dynamic range controls, custom interpolators and other differentiating features to their products.
