The PCM510xA devices belong to a family of monolithic CMOS integrated circuits consisting of a stereo digital-to-analog converter (DAC) and additional support circuitry in a thin small outline size (TSSOP) package. The PCM510xA devices use TI's latest generation of advanced segmented DAC architecture products to achieve excellent dynamic performance and improved tolerance to clock jitter.

With DirectPath charge pump technology, the PCM510xA devices provide a 2.1 VRMS centrally grounded output (designers do not need to connect DC blocking capacitors on the output) and external mute circuitry traditionally associated with single-supply line drivers.

The integrated line driver supports loads as low as 1kΩ per pin, surpassing all other charge pump based line drivers in performance.

The integrated PLL on the device eliminates the need for a system clock (commonly referred to as the master clock), enabling a 3-wire I2C connection and reducing system electromagnetic interference (EMI).

Smart Clock Error and PowerSense undervoltage protection use a two-layer system that eliminates clicks and crackles.

Compared to many traditional switched capacitor DAC architectures, the PCM510xA family is able to keep out-of-band noise down to 20dB, reducing EMI and aliasing in downstream amplifiers/ADCs (measured between 100kHz (OBN typ) to 3MHz) have to).
