MAXREFDES75#: 24-BIT Weigh Scales, 16-Bit DAC, 0 ~ 10V Out

Summary

Weigh scales perform the critical function of mass measurement for a wide variety of industrial applications. From ultra-small reactant amounts to large cargo containers, weighing provides key information in an array of processes from chemical reactions to commodity management. The critical component of any modern weigh scale is the analog-to-digital converter.

The MAXREFDES75# brings a full 24- bit ADC into a high-performance system performing small-signal (down to ±25mV full scale) 24-bit measurements, while generating the high-voltage sensor supply, and producing a 0 to 10V output proportional to the input signal.

Features

  • Ratiometric measurement or measurement compared to a precision voltage reference

  • User-programmable offset and gain calibration for sensor (load cell)

  • User-programmable offset and gain calibration for DAC

  • User-programmable voltage output range mapping
