Frequently Asked Questions
What output voltage does the MCP9700-E/TO produce at 25°C, and how do you convert this to a temperature reading?
The MCP9700-E/TO outputs 500 mV at 0°C and increases linearly at 10 mV/°C, so at 25°C the output is approximately 750 mV. To convert an ADC reading to temperature, subtract the 500 mV offset and divide by the 10 mV/°C sensitivity. For a 10-bit ADC at 3.3 V reference, each ADC count represents about 3.22 mV, providing approximately 0.32°C resolution per count.
How accurate is the MCP9700-E/TO, and in which applications is ±6°C accuracy acceptable?
The MCP9700-E/TO has a maximum accuracy of ±6°C, which is suitable for comfort-level temperature monitoring in room thermostats, fan speed control in desktop computers, over-temperature shutdown in consumer electronics, and refrigerator temperature alerts where precision better than 1°C is not required. For tighter accuracy such as ±0.5°C in medical or laboratory instruments, a more precise digital sensor like the MCP9808 would be a better choice.
For a first prototype using an Arduino or similar 5 V microcontroller, how does the MCP9700-E/TO's TO-92 package simplify wiring?
The TO-92-3 package of the MCP9700-E/TO has 3 through-hole pins spaced at 0.1 inch (2.54 mm) pitch, allowing direct insertion into a breadboard alongside other through-hole components without any soldering or adapter boards. Simply connect VDD to 5 V, GND to ground, and read the output pin with a microcontroller ADC; the 10 mV/°C scale maps cleanly onto a 10-bit ADC, giving approximately 256 count range across a 0°C to 70°C operating span.
