What are the key features of LMT84DCK?
- Ultra-low 9 µA maximum supply current enables battery-powered IoT and wearable temperature sensing with minimal energy consumption
- Class-AB output stage drives ADC inputs directly with a linear voltage-vs-temperature transfer function, eliminating external op-amp buffering
- Built-in short-circuit protection in a compact SOT-23-5 package (2 mm × 1.25 mm body) ensures reliability in harsh or space-constrained environments
What is LMT84DCK used for?
The LMT84DCK is ideal for battery-powered IoT sensors, wearable health monitors, and portable test equipment where analog temperature measurement must consume the minimum possible quiescent current. Its linear voltage output directly interfaces with any microcontroller ADC without additional signal conditioning, simplifying firmware and reducing BOM cost. The compact SOT-23-5 package with short-circuit protection makes it suitable for consumer products that may be exposed to accidental wiring faults.

Frequently Asked Questions
How accurate is the LMT84DCK temperature measurement and over what range does it operate?
The LMT84DCK achieves a maximum accuracy of ±2.7°C across its operating temperature range. It is designed for the -50°C to +150°C measurement range, making it suitable for both cold-environment monitoring applications such as refrigeration and high-temperature industrial sensing on the same hardware platform.
Why is the LMT84DCK suitable for battery-powered designs compared to higher-power analog temperature sensors?
The LMT84DCK draws a maximum of only 9 µA of supply current, which is significantly lower than most analog temperature sensors that consume 50 µA or more. In a design powered by a 1000 mAh coin cell, this 9 µA current budget allows continuous temperature logging for more than 10,000 hours, extending battery life in remote IoT and environmental monitoring systems.
Can the LMT84DCK output drive an ADC input directly, and what voltage does it produce at room temperature?
Yes, the LMT84DCK's Class-AB output stage can directly drive the input of a microcontroller ADC without an external buffer or op-amp. At 25°C room temperature, the output voltage is approximately 1299 mV, and the transfer function is roughly -8.2 mV per °C. This linear relationship allows straightforward ADC-to-temperature conversion using a single multiplication and offset in firmware.
