The PCM510xA 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 PCM510xA devices use the latest generation of TIs advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. Using Directpath™ charge-pump technology, the PCM510xA devices provide 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. The integrated line driver surpasses all other charge-pump based line drivers by supporting loads down to 1 kΩ per pin. The integrated PLL on the device removes the requirement for a system clock (commonly known as master clock), allowing a 3-wire I2S connection and reducing system EMI. Intelligent clock error and PowerSense undervoltage protection utilizes a two-level mute system for pop-free performance. Compared with many conventional switched capacitor DAC architectures, the PCM510xA family offers up to 20 dB lower out-of-band noise, reducing EMI and aliasing in downstream amplifiers/ADCs, measured from the traditional 100-kHz OBN measurements to 3 MHz).
