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 utilize 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.
