Note 1: The MCP9700/9700A family accuracy is tested with VDD = 3.3V, while the MCP9701/9701A accuracy is

tested with VDD = 5.0V.

2: The MCP9700/9700A and MCP9701/9701A family is characterized using the first-order or linear equation,

as shown in Equation 4-2. Also refer to Figure 2-16.

3: SC70-5 package thermal response with 1x1 inch, dual-sided copper clad, TO-92-3 package thermal

response without PCB (leaded).
