Texas Instruments PCM512x / PCM514x Audio Stereo DACs
Texas Instruments PCM512x and PCM514x Audio Stereo Digital-to-Analog Converters (DACs) are a family of monolithic CMOS ICs that include additional support circuitry in a small TSSOP package. These devices use the latest generation of TI's advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. Members of the PCM514x family integrate a fully programmable miniDSP core, allowing developers to integrate filters, dynamic range controls, custom interpolators and other differentiating features to their products. The TI PCM512x family integrates 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.
