FAQ: How to calibrate offset and or phase on the AD7606B?

How does the offset or phase calibration work, what range and resolution do they achieve?

Parents
  • The offset calibration allows to add or subtract up to 128LSB to the ADC conversion result, in order to compensate for any known offset error on the front end (e.g. external resistor mismatch).

    The phase calibration feature allows to delay, on any channel, the sampling instant up to 318.75 us, with a resolution of 1.25us.

    See A.N. 2011 for further details on AD7606B offset and phase calibration feature, and simulate it through the Software model available on the AD7606B product page.
