 +====== CN-0216 Software User Guide======
 +===== Overview =====
 +[[adi>CN0216|CN-0216]] is a precision weigh scale signal conditioning system. It uses the [[adi>AD7791|AD7791]], a low power buffered 24-bit sigma-delta ADC along with two external [[adi>ADA4528-1|ADA4528-1]] zero-drift amplifiers. This solution allows for high dc gain with a single supply.
  
 +Ultralow noise, low offset voltage, and low drift amplifiers are used at the front end for amplification of the low-level signal from the load cell. The circuit yields 15.3 bit noise-free code resolution for a load cell with a full-scale output of 10 mV.
 +
 +This circuit allows great flexibility in designing a custom low-level signal conditioning front end that gives the user the ability to easily optimize the overall transfer function of the combined sensor-amplifier-converter circuit. The [[adi>AD7791|AD7791]] maintains good performance over the complete output data range, from 9.5 Hz to 120 Hz, which allows it to be used in weigh scale applications that operate at various low speeds.
 +
 +This user guide will discuss how to use the evaluation software to collect data from the [[adi>EVAL-CN0216-SDPZ|EVAL-CN0216-SDPZ]] Evaluation Board **(CN-0216 Board)**
