What the MCP9700 does
The MCP9700/9700A and MCP9701/9701A are low-power linear active thermistor ICs that convert temperature directly to an analog voltage without requiring external signal conditioning. This family spans four part numbers available in TO-92, SOT-23, and SC70 packages, covering a wide operating range from -40°C to +150°C. Key specifications include a typical operating current of 6µA, a temperature coefficient of 10.0mV/°C for the 9700 series and 19.5mV/°C for the 9701 series, and an accuracy of ±2°C from 0°C to +70°C for the 'A' variants. These sensors are optimized for direct connection to microcontroller ADCs and are typically used in hard disk drives, portable equipment, home appliances, and general-purpose temperature monitoring applications where remote sensing and low power consumption are critical.
