TI PCM5100APW

The PCM510xA devices are a family of monolithic CMOS ICs consisting of stereo DACs and additional support circuitry in a TSSOP package. The PCM510xA devices utilize TI's latest generation advanced segmented DAC architecture to achieve excellent dynamic performance and enhanced tolerance to clock jitter. With DirectPath charge pump technology, the PCM510xA devices provide a 2.1 VRMS ground-centered output — eliminating the need for DC-blocking capacitors at the output and the external muting circuitry traditionally associated with single-supply line drivers. The integrated line driver supports loads as low as 1 kΩ per pin, surpassing all other charge pump-based line drivers in performance. The on-chip PLL eliminates the need for a system clock (commonly referred to as a master clock), enabling a 3-wire I2C connection and reducing system EMI. Intelligent clock error detection and PowerSense undervoltage protection form a dual-layer system that eliminates clicks and pops.
