EVAL-CN0552-PMDZ

EVAL-CN0552-PMDZ is an evaluation board for capacitance to digital converter with extended range. The EVAL-CN0552-PMDZ is a PMOD form-factor evaluation board for the AD7746, a high resolution, Σ-Δ capacitance-to-digital converter (CDC). The architecture features inherent high resolution (24bit no missing codes, up to 21bit effective resolution), high linearity (±0.01%) and high accuracy (±4fF factory calibrated).

• Interfaces to single or differential floating sensors
• Resolution down to 4aF (that is, up to 21 ENOB)
• Accuracy of 4fF and Linearity of 0.01%
• Common mode (not changing) capacitance up to 17pF
• Full-scale (changing) capacitance range: ±4pF
• Tolerant of parasitic capacitance to ground up to 60pF
• Update rate: 10Hz to 90Hz
• Simultaneous 50Hz and 60Hz rejection at 16Hz
