Mikroe ISO ADC 5 Click features the Maxim Integrated MAX22530 12-bit, analog-to-digital converter (ADC), providing 5kVRMS isolation. The ADC and all field-side circuits are powered by an integrated, isolated DC-DC converter. It can verify field-side functionality even when there is no input signal or other field-side supply. The 12-bit ADC core has a sample rate of typically 20ksps per channel, where ADC data is available through the SPI interface.
