Sensor Typical Accuracy Performance

Note:

This accuracy data from the production system represents the typical accuracy performance of the

MCP98242 Memory Module Temperature Sensor. The MCP98242 production methodology is also used for

the MCP9843/98243 to achieve the same typical accuracy performance.
