Product Summary

The PCM1748E/2K is a CMOS, monolithic, integrated circuit which includes stereo Digital-to-Analog Converters (DAC) and support circuitry in a small SSOP-16 package. The PCM1748E/2K utilizes Texas Instrument’s enhanced multilevel delta-sigma architecture that employs fourth-order noise shaping and 8-level amplitude quantization to achieve excellent dynamic performance and improved tolerance to clock jitter. The applications of the PCM1748E/2K include A/V receivers, DVD movie players, DVD add-on cards for high-end PCS, HDTV receivers, car audio systems, other multichannel audio systems.
