具有 miniDSP 和智能放大器功能的 114dB 32 位立体声差分输出 DAC 32-VQFN -25 to 85
The PCM5252 is a monolithic CMOS integrated circuit that includes a stereo digital-to-analog converter and additional support circuitry in a small QFN package. The PCM5252 uses the latest generation of ’s advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter.
The PCM5252 integrates a fully programmable miniDSP core, allowing developers to integrate filters, dynamic range controls, custom interpolators and other differentiating features to their products.
The PCM5252 integrates ROM components of TIs PurePath™ Smart Amp technology, which allows speakers to be driven with more peak power than their average-power rating, without damage to the speaker by voice coil over excursion or thermal overload.
The PCM5252 provides 4.2VRMS ground-centered differential 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 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.
