The PCM514x 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 PCM514x uses the latest generation of TIs advanced
segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock
Members of the PCM514x family integrate a fully programmable
miniDSP core, allowing developers to integrate filters, dynamic range controls, custom
interpolators, and other differentiating features to their products.
The PCM514x provides 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, allowing the PCM514x to drive up to 10 products
in parallel, such as LCD TV, DVDR, and AV receivers.
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
