PCM1754-Q1 - Texas Instruments

PCM1754-Q1 Audio Digital-to-Analog Converter

The PCM175x-Q1 family of devices 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, which employs 4th-order noise shaping and 8-level amplitude quantization to achieve excellent dynamic p.
