Description

The MCP9701AT-E/TT is a precision analog temperature sensor IC utilizing a linear active thermistor sensing principle. It outputs a voltage signal that scales linearly with temperature (typically 10 mV/°C with a 500 mV offset at 0°C), requiring only a single ADC channel on a host microcontroller for digitization. This design eliminates the need for external signal conditioning circuits.

Engineered for stability and reliability, the sensor operates across a broad industrial temperature range from -40°C to +125°C. Its low power consumption and fast thermal response time make it suitable for battery-powered devices, embedded systems, and thermal management control loops in consumer electronics, automotive modules, and HVAC systems.

Frequently Asked Questions

What is the output signal of the MCP9701AT-E/TT sensor and how do I interface it with an Arduino?

The MCP9701AT-E/TT provides a linear analog voltage output. The output voltage follows the formula VOUT = 500 mV + (10 mV/°C * T). To use it with an Arduino, connect VDD to 3.3V or 5V, GND to ground, and the VOUT pin to any analog input pin (e.g., A0). Read the analog value and convert it to temperature using the formula in your code.

What is the operating voltage range and can it run on a 3.3V system?

Yes, the sensor is fully compatible with 3.3V systems. Its specified operating voltage range is 3.1V to 5.5V, making it suitable for both 3.3V and 5V microcontroller platforms like ESP32, STM32, and Raspberry Pi. Ensure your supply voltage is within this range for accurate readings.

What is the typical accuracy and temperature range of this sensor?

The MCP9701AT-E/TT is rated for an operating temperature range of -40°C to +125°C. Its typical accuracy is ±2°C within the 0°C to +70°C range. For applications requiring precision outside this core range or across the full span, consult the datasheet for detailed error curves and consider calibration.

Does this sensor require any external components for basic operation?

For basic temperature reading, no external components are strictly necessary besides power supply decoupling. For optimal noise immunity, it is recommended to place a 0.1 µF ceramic capacitor close to the sensor's VDD pin. The output is a high-impedance voltage source suitable for direct connection to a microcontroller ADC input.
