PCM1680
Description
The PCM1680 is a CMOS, monolithic integrated circuit which features eight 24-bit audio digital-to-analog converters (DACs) and support circuitry in a small SSOP-28. The DACs use TI's enhanced multilevel delta-sigma (ΔΣ) architecture to achieve excellent signal-to-noise performance and a high tolerance to clock jitter.
