The ADSD-1420S and ADSD-1420EX dual-sampling A/D converters are 14bit resolution modules that can deliver 20MSamples/s without any missing code over their full temperature range. The ADSD-1420S is designed for commercial applications and has an operating temperature range of 0 to +70ºC, while the ADSD-1420EX has an operating temperature range of -55 to +125ºC, suitable for more demanding industrial or military designs. The new edge-triggered modules have a ±2.5V input range and are suited to both time and wideband frequency-domain applications. They offer a signal-to-noise-ratio performance of 75dB, plus a total harmonic distortion of -80dB, allowing them to meet low-noise requirements.
