PCM1754 106dB SNR Stereo Audio DAC (H/W Control) | TI.com


106dB SNR Stereo Audio DAC (H/W Control)



The PCM175x devices are stereo digital-to-analog converters (DACs) based on TI’s enhanced delta-sigma architecture which employ 4th-order noise shaping and 8-level amplitude quantization to achieve excellent dynamic performance and improved clock jitter tolerance. The PCM175x devices easily interface with audio DSP and decoder chips because of the devices’ support of industry-standard audio data formats with 16- and 24-bit data. The PCM175x devices can be controlled in a hardware mode, or a full set of user-programmable functions is accessible through a three-wire serial control port, which supports register-write functions.

The PCM1753 is pin-compatible with the PCM1748, PCM1742, and PCM1741, except for pin 5.
