The IP-16DAC is a Type II IndustryPack module delivering 16 channels of 16-bit digital-to-analog conversion for precision analog output generation. Built on Crystal Semiconductor CS4333 stereo DACs in 2’s complement format, it achieves 94 dB dynamic range and 0.003% THD, making it suitable for high-fidelity applications demanding low distortion and stable output. The module employs Linear Technology LT1114 precision op-amps with picoamp input bias currents, RF-filtered analog power, isolated analog ground planes, and internal de-glitching hardware for fast settling times. Factory calibration and 3 ppm/°C drift specification ensure high accuracy and repeatability across temperature variations.
