Key Features
- Linear analog output of 10 mV/°C with ±4°C maximum accuracy for direct ADC connection without firmware linearization
- Ultra-compact SC70-5 package measuring 2 mm × 1.25 mm for space-critical PCB designs
- 3.1 V to 5.5 V supply range with less than 6 µA typical supply current for battery-powered sensing
Applications
The MCP9701AT-E/LT is used in consumer electronics, portable devices, and IoT sensors where a low-cost analog temperature output needs to connect directly to a microcontroller ADC input. Its 10 mV/°C linear slope simplifies firmware by eliminating lookup table linearization for temperature ranges from -40°C to +125°C. Industrial and HVAC control boards also use it to measure ambient or component temperatures where minimal board area is available.

Frequently Asked Questions
What output sensitivity and accuracy does MCP9701AT-E/LT provide for an ADC-based temperature measurement?
The MCP9701AT-E/LT outputs 10 mV per °C with a ±4°C maximum accuracy over its operating range, so a 10-bit ADC with a 3.3 V reference can resolve temperature to approximately 0.3°C per LSB without additional signal conditioning.
How small is the MCP9701AT-E/LT package, and what temperature range does it cover?
The device is housed in a 5-pin SC70 package measuring only 2 mm × 1.25 mm × 0.95 mm, and it covers an operating temperature range of -40°C to +125°C, making it ideal for embedded temperature monitoring in tight board layouts.
How does MCP9701AT-E/LT compare to a thermistor in a low-power wearable sensor design?
Unlike a resistive thermistor that needs a voltage divider and firmware linearization, MCP9701AT-E/LT produces a linear 10 mV/°C voltage directly readable by any ADC while consuming less than 6 µA, reducing firmware complexity and BOM in wearable or coin-cell-powered designs.
