Product Overview
The MCP9700/9700A and MCP9701/9701A are analog temperature sensors featuring a Linear Active Thermistor Integrated Circuit (IC). These low-cost, low-power devices convert temperature into an analog voltage, eliminating the need for additional signal-conditioning circuits required by traditional resistive sensors. They are optimized for direct connection to microcontroller Analog-to-Digital Converters (ADCs), offering a typical sensitivity of 10.0 mV/C for the MCP9700/9700A and 19.5 mV/C for the MCP9701/9701A. The sensors are designed for a wide operating voltage range and low current consumption, making them suitable for various temperature monitoring applications.
