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.

Features

  • Available packages:
    • SC70-5, SOT-23-3, and TO-92-3 (not available with the MCP9700B)
  • Wide temperature measurement range:
    • -40°C to +125°C (extended temperature)
    • -40°C to +150°C (high temperature)
  • Accuracy:
    • ±1°C (max.), +20°C to +70°C (MCP9700B)
    • ±2°C (max.), 0°C to +70°C (MCP9700A and MCP9701A)
    • ±4°C (max.), 0°C to +70°C (MCP9700 and MCP9701)
  • Tiny analog temperature sensor
  • Optimized for analog-to-digital converters (ADCs):
    • 10 mV/°C (typical) (MCP9700, MCP9700A, and MCP9700B)
    • 19.5 mV/°C (typical) (MCP9701 and MCP9701A)
  • Wide operating voltage range:
    • VDD = 2.3 V to 5.5 V (MCP9700, MCP9700A, and MCP9700B)
    • VDD = 3.1 V to 5.5 V (MCP9701 and MCP9701A)
  • Low operating current of 6 µA (typical)
  • Optimized to drive large capacitive loads
