FAQ: What is the equation for calculating Internal Temperature Sensor for AD7124-4/AD7124-8 in unipolar mode?

For AD7124-4/AD7124-8 the sensitivity of the internal temperature sensor is 13,584 codes/°C, approximately when Vref = 2.5V. Both unipolar and…

Answer: To ensure synchronization between multiple AD7124-4/AD7124-8 devices, the same master clock must be used for all devices. If the AD7124 internal clock has been used, then one ADC serves as the master and uses its own internal clock and this clock…

Answer: For a system that requires multiple channels, one AD7124-8 can support up to 8 differential/15 single ended input channels and one AD7124-4 can support up to 4 differential/7 single ended input channels. If the system requires a greater number…

FAQ: How are the offset and gain coefficients applied to the data conversion of AD7124-4/AD7124-8?

The following equations show the calculations associated with the offset and gain for both unipolar and bipolar modes of operation. Note that the AD7124…

FAQ: After performing AD7124-4/AD7124-8 calibrations, do I need to use the offset and gain coefficients in my data output code calculations?

When the ADC performs the offset and gain calibrations, the resulting offset and gain coefficients are updated…

As discussed in What is the data output coding format used in AD7124-4/AD7124-8?  the ADCs operate in unipolar or bipolar coding modes.

When unipolar mode is selected the ADC output code for any analog input voltage applied to the analog inputs can be…
