QMC350 20-Channel 16-Bit Analog Input Module (VITA 93)

The Acromag QMC350 is a VITA 93, 20-channel, 16-bit analog input module engineered for high-speed, high-accuracy data acquisition in rugged embedded systems. Each channel features its own 16-bit ADC for true simultaneous sampling at up to 1MSPS, with software-selectable single-ended and differential voltage ranges. Its ultra-compact mezzanine design makes it ideal for defence, aerospace, industrial, and SWaP-C-optimised applications requiring dense, precision analog measurement.
