PCM1782 Audio Digital-to-Analog Converter

PCM1782 Audio Digital-to-Analog Converter

The PCM1780/81/82 is a CMOS, monolithic, integrated circuit, which includes stereo digital-to-analog converters and support circuitry in a small 16-lead SSOP package. The data converters use TI’s enhanced multilevel delta-sigma architecture to achieve excellent dynamic performance and improved toler.
