Company Profile

analog temperature sensor MICROCHIP MCP9701T-E/TT optimized for direct microcontroller adc connection

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 sensors convert temperature into an analog voltage, eliminating the need for external signal conditioning circuits required by traditional resistive sensors like thermistors. They offer high accuracy and are optimized for direct connection to microcontroller ADCs. The sensors are immune to parasitic capacitance and can drive large capacitive loads, providing flexibility in PCB layout and improving output transient response. They are ideal for applications requiring measurement of relative temperature changes.
