Microchip MCP9700/9700A and MCP9701/9701A Datasheet
The MCP9700/9700A and MCP9701/9701A families are low‑power linear active thermistor ICs that convert temperature to an analog voltage. They are offered in SC‑70‑5, SOT‑23‑5, and TO‑92‑3 packages and are optimized for direct connection to ADC inputs of microcontrollers.
Key features include a wide operating voltage range (2.3 V‑5.5 V for MCP9700/9700A, 3.1 V‑5.5 V for MCP9701/9701A), low operating current (6 µA typical), and temperature coefficients of 10 mV/°C (MCP9700/9700A) or 19.5 mV/°C (MCP9701/9701A). Accuracy can be improved with calibration at a known temperature.
