The PCM5122PW is a 2VRMS DIRECTPATH 112dB audio stereo Digital to Analogue Converter with PCM interface and fixed audio processing. The PCM512x uses the latest generation of its advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. Members of the PCM512x 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. The PCM512x provides 2.1VRMS ground centred 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. By supporting loads down to 1kR, the PCM512x can essentially drive up to 10 products in parallel.
