Product Description

DESCRIPTION
The PCM1742 is a CMOS, monolithic, integrated circuit which includes stereo digital-to-analog converters (DACs) and support circuitry in a small SSOP-16 package. The data converters use Texas Instruments" enhanced multilevel delta-sigma archi-tecture that employs fourth-order noise shaping and 8-level amplitude quantization to achieve excellent dynamic performance and improved tolerance to clock jitter.
