NOTE
1: These devices use an external temperature sensor. Accuracy of the total solution is a function of the accuracy of the external sensor.
2: TCN75 idle current is 250 μ A. This device also has a Software Shutdown mode that reduces supply current to <1 μ A.
3: MCP9805 max. accuracy measured at 85°C.
