Introduction

The LMT84DCKR is an analog and digital temperature sensor specifically designed to work in harsh environments. It features an exceptionally wide operating temperature range of -40°C to +125°C (-40°F to +257°F), and is IP67 water and dustproof rated. The LMT84DCKR is a low-power device, using a low current draw of 200uA at room temperature, with a standby current consumption of 0.33uA at +25°C.

Application Field and Working Principle

The LMT84DCKR is mainly used in temperature monitoring applications such as medical laboratories, scientific research, industrial processes, and automotive applications. It offers a wide range of accuracy (±2%, ±3%, ±5%) and output types (analog voltage, digital I2C, SPI, and PWM). The LMT84DCKR is an ideal solution for applications that require high-accuracy temperature measurement with a low energy consumption.

The LMT84DCKR works using a thermistor-based sensing element, which not only has a high temperature accuracy (±1°C over the temperature range), but also has a fast response time (less than 1 second). The LMT84DCKR operates in two different modes: analog and digital. In analog mode, the output signal voltage is proportional to the environmental temperature, and in digital mode, the output is in the form of digital words (I2C, SPI, or PWM).
