Frequently Asked Questions
How does the MCP9701AT-E/TO output temperature data and what ADC resolution is needed?
The MCP9701AT-E/TO provides a linear analog voltage output with a sensitivity of 19.5 mV/°C. For a 0°C to 70°C range, the output spans approximately 1.365V. A 10-bit ADC at 3.3V reference yields about 0.32°C resolution per LSB, which comfortably meets the ±4°C accuracy specification for most consumer and industrial monitoring applications.
What is the supply current requirement of the MCP9701AT-E/TO and how long can it run on a coin cell?
The MCP9701AT-E/TO draws a maximum of 0.015 mA (15 µA) from its 3.1V to 5.5V supply. On a typical 225 mAh CR2032 coin cell at 3V, the sensor alone could theoretically run for over 15,000 hours, making it an excellent choice for long-life battery-operated wireless sensor nodes.
Is the MCP9701AT-E/TO suitable for outdoor temperature monitoring applications requiring a wide temperature range?
Yes, the MCP9701AT-E/TO is rated for an operating temperature range of -40°C to +125°C, covering most outdoor and automotive ambient monitoring scenarios. Its ±4°C maximum accuracy is acceptable for HVAC control, weather stations, and outdoor equipment thermal management, especially at this low 0.015 mA current consumption.
When would a designer choose MCP9701AT-E/TO over a digital temperature sensor like the MCP9808?
A designer would choose the MCP9701AT-E/TO when analog output is preferred to avoid I2C/SPI bus overhead and when ±4°C accuracy is sufficient. At 0.015 mA, it consumes significantly less power than most digital sensors, and the TO-92 through-hole package suits prototyping or rugged through-hole assembly processes where SOT-23 SMD parts are harder to hand-solder.
