MAXIM INTEGRATED MAX22530 Self-Powered Isolated ADC | New Product Brief

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.

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 12-bit ADC core has a sample rate of 20 kilosamples per second per-channel. ADC data is available through the SPI interface either directly or filtered. 

Each input has a comparator with programmable high and low thresholds, and an interrupt is asserted when any input crosses its programmed level based on the mode setting. 

The comparator output pin (COUT_) is high when the input voltage is above the upper threshold and low when it is below the lower threshold in digital input mode. 

The MAX22530 is packaged in a 16-pin wide SOIC with a -40°C to +125°C operating temperature range.
