MCP9700/MCP9701 Thermistor ICs
Microchip's MCP9700 and MCP9701 low-power linear active thermistor ICs provide a low-cost solution
Microchip's low-power MCP9700, MCP9700A, MCP9700B, MCP9701, and MCP9701A analog temperature sensors with linear active thermistor integrated circuit (IC) convert temperature to analog voltage. These sensors have accuracy of ±1°C from +20°C to +70°C (MCP9700B), ±2°C from 0°C to +70°C (MCP9700A and MCP9701A), and ±4°C from 0°C to +70°C (MCP9700 and MCP9701) and consume 6 µA (typical) of operating current. These sensors provide a low-cost solution for applications requiring relative temperature change measurement.
