PCM1748
Description
The PCM1748 is a CMOS, monolithic, integrated circuit which includes stereo digital-to-analog converters (DAC) and support circuitry in a small SSOP-16 package. The data converters use Texas Instruments' 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.
