MICROCHIP Low Power Linear Active Thermistor IC, 2.3V-5.5V, SOT-23
MICROCHIP low power linear active thermistor IC in a 3-pin SOT-23 package. Features ±2°C accuracy and 2.3V to 5.5V operating voltage range.
The MICROCHIP Low Power Linear Active Thermistor IC in a 3-pin SOT-23 package offers an efficient solution for converting temperature to analogue voltage. Designed as an analogue temperature sensor, it provides an accuracy of ±2°C from 0°C to 70°C while consuming a typical operating current of just 6μA.
This thermistor IC does not require additional signal conditioning circuitry, and its voltage output pin (VOUT) can be directly connected to the ADC input of a microcontroller. By implementing this device, you can avoid the biasing circuit development overhead typically associated with traditional thermistor solutions.
The device is immune to the effects of parasitic capacitance and is optimised to drive large capacitive loads. This provides excellent printed circuit board (PCB) layout design flexibility, enabling the sensor to be remotely located from the microcontroller. It is highly suitable for applications requiring the measurement of relative temperature changes.
