The MCP9700AT-E/LT is a compact analog temperature sensor IC from Microchip, also known as a Linear Active Thermistor, delivered in a tiny 5-SC-70 surface-mount package for tape-and-reel shipment. This low-power temperature sensor provides a linear analog output of 10mV/°C with a 500mV offset at 0°C, supporting negative temperature measurement without negative power rails, and it works within a supply voltage range of 2.3V to 5.5V over -40°C to +125°C, offering ±2°C accuracy between 0°C and 70°C while drawing only 6μA typical operating current, and it can directly connect to MCU ADC inputs without extra signal conditioning circuits.
Key highlights of this analog temperature sensor include:
● Ultra-low quiescent current for battery-powered designs
● Linear voltage output that simplifies temperature conversion calculation
● Built-in 500mV zero offset for negative temperature detection
● Immunity to parasitic capacitance and stable drive for capacitive loads
● Wide supply compatibility with low-voltage embedded systems
Application scenarios
● Temperature monitoring for household home appliances and portable battery packs;
● Thermal protection and thermal sensing in office automation and consumer entertainment devices
● General ambient temperature detection for industrial low-cost sensing nodes
● Internal temperature tracking for PC peripherals and small electronic modules
● Environmental temperature sampling for low-power IoT sensor nodes.
