Temperature sensors with analog or digital outputs are critical components in ensuring the accurate monitoring and control of heat. The MAX6689UP34+T application field and working principle is an example of such a sensor and its uses.
The MAX6689UP34+T is a surface mount NTC thermistor that combines two temperature sensing elements with a small signal amplifier. This provides an output voltage that is proportional to absolute temperature. This output can be used as an analog signal, for linear attitude temperature measurement, when connected to a separate system’s ADC input, or for digital temperature control directly from a microcontroller.
The integral amplifier has a gain of 5.6 and 24-bit precision for accurate reading across a wide range of temperatures. With a wide temperature range of -55°C to 150°C, the MAX6689UP34+T provides good performance for both consumer electronics devices like laptops or mobile phones and industrial systems. This temperature sensing chip is also provided with an absolute maximum rating of 20.3mA max, an operating voltage from 2.7V to 5.5V, and a low temperature coefficient (TC) of +0.3°C/V.
Equipped with an internal fault detection system, the MAX6689UP34+T enables the user to set a trip point for the temperature monitoring circuit, and allows for temperature calibration. This feature also helps to improve its accuracy in a wide variety of applications, and is especially useful for environmental temperature monitoring.
The working principle of the MAX6689UP34+T is based on NTC thermistor technology. Its three paired thermistor elements provide an electrical resistance that is proportional to the absolute temperature. This resistance is converted to a proportional voltage by the amplifier, and the resulting voltage magnitude is proportional to temperature. This amplified voltage is then available to be used for temperature measurement applications.
In summary, the MAX6689UP34+T is a versatile temperature sensing chip with several features that make it suitable for a range of temperature measurement and monitoring applications. In addition to providing a reliable analog output, it also offers a one-stop solution for environmental temperature monitoring, with an integrated fault detection system and calibration capability.
