Temperature Sensors - NTC Thermistors

NTCS0805E3474JXT is a temperature-sensitive chip manufactured by EPCOS Inc. It is designed for the temperature sensing applications and offers an accurate solution to the temperature sensing needs. The NTCS0805E3474JXT includes a self-contained thermistor with a 12-bit digital analog converter (DAC) that provides a high level of accuracy. The thermistor and DAC are connected using a 4-wire configuration, which allows for external calibration of the DAC.

Application Field of NTCS0805E3474JXT

NTCS0805E3474JXT is applicable to many temperature sensing applications, such as industrial, automotive, consumer and medical. The chip has a flexible range of 2.4V to 11V, with a continuous response temperature of –20°C to 125°C and a selectable wider calibration range of -40° to +185°C. Its low-power consumption and small size makes it ideal for embedded systems.

The NTCS0805E3474JXT has a wide range of features, such as a 12-bit digital analog converter (DAC) with an internal temperature-to-voltage conversion that eliminates the need for external resistors. It also features a wide temperature sensing range, a selectable high- or low-temperature calibration range, a fast readout rate of up to 5kHz and a high accuracy of up to 1°C. Additionally, its low power consumption allows for extended battery life.

Working Principle of NTCS0805E3474JXT

The NTCS0805E3474JXT operates using the principle of temperature-sensitive thermistors. An NTCS0805E3474JXT thermistor is a temperature-dependent resistor whose resistance decreases with increasing temperature. It works by converting a change in temperature into a change in resistance. This change in resistance is measured by the DAC, which then converts the resistance into a voltage.

The NTCS0805E3474JXT thermistor is composed of two parts, the sensing element and the calibration resistor. The sensing element is what detects the temperature, while the calibration resistor is responsible for calibrating the DAC. These two elements are connected using a 4-wire configuration. When the temperature changes, the resistance of the thermistor changes, which causes a voltage change across the calibration resistor. This voltage change is measured by the DAC, and the result is a temperature measurement.

The NTCS0805E3474JXT chip is ideal for medium- to high-precision temperature sensing applications, due to its high accuracy and low-power consumption. Its wide temperature sensing range, coupled with the internal temperature-to-voltage conversion eliminates the need for external resistors, making it an ideal choice as a temperature sensor for many applications.
