What are the key features of MCP9700A-E/TO?
- Linear 10 mV/°C temperature-to-voltage conversion eliminates lookup tables and linearization firmware
- ±4°C maximum accuracy across the operating range with zero-power standby for battery-sensitive applications
- Through-hole TO-92-3 plastic package enables rapid prototyping and hand-soldering on through-hole PCBs
- Single-supply analog output directly readable by ADC inputs with no external components required
What is MCP9700A-E/TO used for?
MCP9700A-E/TO is used in hobbyist projects, educational kits, and low-cost industrial thermometers where a simple analog voltage output proportional to temperature is sufficient for monitoring purposes. Its 10 mV/°C linear output connects directly to a microcontroller ADC pin without requiring I2C or SPI interfaces, making it ideal for Arduino-based temperature loggers, HVAC controllers, and fan speed control circuits. The TO-92-3 through-hole package simplifies breadboard prototyping and is widely used in consumer appliances and home automation sensor nodes.

Frequently Asked Questions
What output voltage does MCP9700A-E/TO produce at 25°C and what is the output slope?
At 25°C, MCP9700A-E/TO produces an output voltage of 750 mV with a linear transfer function of 10 mV/°C. This means at 0°C the output is 500 mV and at 50°C it is 1000 mV, allowing a microcontroller ADC with a 3.3 V or 5 V reference to easily convert the voltage reading to a temperature value without any lookup table or linearization algorithm.
How accurate is MCP9700A-E/TO and over what temperature range does it operate?
MCP9700A-E/TO has a maximum accuracy of ±4°C over its operating temperature range, which typically spans -40°C to 125°C. The ±4°C tolerance is sufficient for applications such as fan speed control, over-temperature alarms, and ambient temperature monitoring where high-precision measurement is not required and the cost of a calibrated digital sensor cannot be justified.
Can MCP9700A-E/TO be connected directly to a 3.3 V microcontroller ADC input without external components?
Yes, MCP9700A-E/TO requires only a supply voltage (2.3 V to 5.5 V) and a bypass capacitor of at least 100 nF on the VDD pin to operate correctly. Its analog output is ratiometric to the supply and can be directly connected to any ADC input pin on a 3.3 V or 5 V microcontroller, making it one of the simplest temperature sensor interfaces with zero additional active components needed.
For a classroom prototyping project, how does MCP9700A-E/TO in TO-92-3 compare to a digital I2C temperature sensor?
The TO-92-3 through-hole package of MCP9700A-E/TO is easily insertable into a breadboard and its analog output requires only reading a single ADC channel, whereas a digital I2C temperature sensor requires configuring I2C addresses, reading 2-byte register values, and handling communication timing. For a beginner-level 10 mV/°C analog output lesson, MCP9700A-E/TO offers a simpler learning path, though a digital sensor delivers better accuracy (typically ±0.5°C vs ±4°C) and longer cable runs for production systems.
