EVAL-CN0216-ARDZ

EVAL-CN0216-ARDZ is an Arduino compatible high gain weigh scale design (CN0216) evaluation board. CN-0216 is a precision weigh scale signal conditioning system. It uses the AD7791, a low power buffered 24bit sigma-delta ADC along with dual external ADA4528-1 zero-drift amplifiers. This solution allows for high DC gain with a single supply. 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. 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 AD7791 maintains good performance over the complete output data range, from 9.5Hz to 120Hz which allows it to be used in weigh scale applications that operate at various low speeds.
