The PCM5142PW is a monolithic CMOS stereo Digital-to-analog Converter with additional support circuitry. The PCM514x uses the latest generation of TIs advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. It integrates a fully programmable miniDSP core, allowing developers to integrate filters, dynamic range controls, custom interpolators and other differentiating features. The PCM514x provides 2.1VRMS 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. The integrated line driver surpasses all other charge-pump-based line drivers by supporting loads down to 1kR. The integrated PLL on the device removes the requirement for a system clock, allowing a 3-wire I2S connection and reducing system EMI.
