Product Description
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 external signal conditioning circuits. They are optimized for Analog-to-Digital Converters (ADCs) and offer a wide operating voltage range and low operating current. These sensors are ideal for applications requiring accurate temperature measurement and relative change monitoring, providing flexibility in PCB layout due to their ability to drive large capacitive loads.
