MAXIM INTEGRATED MAX22530 Self-Powered Isolated ADC
Maxim Integrated MAX22530 Self-Powered Isolated ADCs are galvanically isolated, 4-channel, multiplexed, 12-bit, analog-to-digital converters (ADC) in the MAXSafe™ family product line.
An integrated, isolated DC-to-DC converter powers all field-side circuitry, enabling field-side diagnostics even when no input signal is present. The MAX22530 continually digitizes the input voltage on the field-side of an isolation barrier and transmits the data across the isolation barrier to the logic-side of the devices, where the magnitude of the input voltage is compared to programmable thresholds.
The ADC allows for flexible control through a programmable comparator, where data is available through the SPI interface either directly or filtered. Each input has a comparator with programmable high and low thresholds. An interrupt is asserted when any input crosses its programmed level based on the mode setting. With filtering enabled, the comparator uses the moving average of the last 4 ADC readings. A precision internal 1.8V reference is used that has a maximum error of ±2% over the entire operating temperature range from -40°C to 125°C.
