What are the key features of MCP9701T-E/LT?
- 19.53 mV/°C linear output sensitivity enables direct ADC reading without a Wheatstone bridge or precision resistor network
- ±6 °C maximum accuracy across the full operating range in a 2 mm x 1.25 mm SC-70-5 package for ultra-compact designs
- 3.1 V to 5.5 V supply range makes it compatible with 3.3 V and 5 V microcontroller ADC inputs without additional signal conditioning
What is MCP9701T-E/LT used for?
The MCP9701T-E/LT is used in portable consumer electronics, IoT sensor nodes, and battery management systems where a tiny, low-cost temperature sensor with a direct linear voltage output is needed. Its 19.53 mV/°C sensitivity allows a microcontroller's built-in 10-bit ADC to resolve approximately 0.5 °C per step at 5 V supply, making firmware implementation straightforward. The SC-70-5 package—just 2 mm long—fits into space-constrained PCB regions such as wearables, smart plugs, and HVAC controllers.

Frequently Asked Questions
What output sensitivity does MCP9701T-E/LT provide, and how does it simplify ADC interface design?
The MCP9701T-E/LT outputs 19.53 mV per degree Celsius, which maps directly to a microcontroller ADC input without requiring a Wheatstone bridge, amplifier, or linearization table. At a 5 V reference, a 10-bit ADC resolves approximately 4.88 mV per step, allowing temperature resolution near 0.25 °C per LSB, which is practical for HVAC, consumer appliance, and portable instrument designs.
How small is the MCP9701T-E/LT SC-70-5 package, and in which space-constrained applications does this provide a competitive advantage?
The SC-70-5 package measures 2 mm x 1.25 mm x 0.95 mm, making it one of the smallest 5-pin surface-mount packages available. This footprint is ideal for wearable health monitors, smart card readers, and densely packed IoT modules where a standard SOT-23-5 part would consume over twice the board area, enabling more components per square centimeter on the PCB.
What accuracy limitation should engineers consider when using MCP9701T-E/LT versus a digital temperature sensor like MCP9800?
The MCP9701T-E/LT has a ±6 °C maximum accuracy, compared to ±0.5 °C for a precision digital sensor like MCP9800. This broader tolerance makes it unsuitable for medical-grade or high-precision industrial calibration but is adequate for thermal protection, fan control, or comfort sensing where a few degrees of error is acceptable. For tighter accuracy requirements, a higher-grade analog sensor or a digital alternative should be selected.
