3 Description
The PCM510xA devices are a family of monolithic
CMOS-integrated circuits that include a stereo digitalto-
analog converter and additional support circuitry in
a small TSSOP package. The PCM510xA devices
use the latest generation of TI’s 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).
