Frequently Asked Questions
What is the output sensitivity of the MCP9701T-E/TT, and how does it connect to a microcontroller ADC?
The MCP9701T-E/TT produces a linear analog output with a sensitivity of 19.5 mV per degree Celsius. This voltage is read directly by any microcontroller ADC pin without requiring an I2C or SPI interface. At 0°C the output is approximately 400 mV, and it rises linearly to about 2.325 V at 100°C, making temperature calculation straightforward with a 10-bit or 12-bit ADC.
Over what temperature range does the MCP9701T-E/TT operate, and what is its maximum accuracy?
The MCP9701T-E/TT operates over a temperature range of -40°C to 125°C and maintains a maximum accuracy of ±6°C across this range, which is sufficient for ambient monitoring in consumer and industrial applications. For tighter accuracy requirements below ±2°C, Microchip offers the MCP9700 and MCP9701A variants with improved accuracy specifications.
How does the SOT-23-3 package size of the MCP9701T-E/TT benefit placement on a dense PCB?
The SOT-23-3 package measures only 2.9 mm × 1.3 mm, making it one of the smallest commercially available temperature sensor packages. This compact footprint allows placement very close to the heat source being monitored, improving thermal response time, and it easily fits into the tight component spacing of wearable devices, IoT modules, and portable medical equipment with 3.3 V or 5 V power rails.
Is the MCP9701T-E/TT suitable for a 3.3 V single-supply battery-powered system?
Yes, the MCP9701T-E/TT operates from a single supply of 3.1 V to 5.5 V, making it fully compatible with 3.3 V regulated supplies from LDOs or boost converters in battery-powered designs. Its typical quiescent current of only 6 µA ensures negligible impact on battery life, making it ideal for continuous temperature monitoring in IoT nodes running on coin cell or AA batteries.
