Product Summary

The PCM63P-K is a precision 20-bit digital-to-analog converter with ultra-low distortion (–96dB max with a full scale output; PCM63P-K). Incorporated into the PCM63P-K is a unique Colinear dual-DAC per channel architecture that eliminates unwanted glitches and other nonlinearities around bipolar zero. The PCM63P-K also features a very low noise (116dB max SNR; A-weighted method) and fast settling current output (200ns typ, 2mA step) which is capable of 16-times oversampling rates.
