PCM1609A DELTA-SIGMA DIGITAL-TO-ANALOG CONVERTER

The PCM1609A is a CMOS, monolithic integrated circuit that features eight 24-bit audio digital-to-analog converters (DACs) and support circuitry in a small LQFP-48 package. The DACs use Texas Instruments (TI) enhanced multilevel delta-sigma architecture that employs fourth-order noise shaping and 8-level amplitude quantization to achieve excellent signal-to-.
