Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure compatibility with required operating temperatures and package variants. Confirm current availability status as distribution channels may indicate limited stock or end-of-life constraints. Cross-reference the datasheet revision history to validate pinout and electrical characteristics match the design requirements before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring simultaneous monitoring of multiple high-voltage cells without external multiplexing. Evaluate the 72 V maximum supply limit against the total pack voltage to ensure safe operation. Consider the SPI interface speed and fault response latency relative to the system's safety requirements. Verify that the TSSOP-38 package dimensions fit the available PCB real estate constraints.
