Temperature Sensors - Analog and Digital Output
The LM35H high-accuracy, high-performance, silent digital temperature sensor is one of the most widely used temperature sensors on the market today. With its excellent accuracy and wide temperature range, it can be used for a variety of applications such as aerospace, automotive, medical, and industrial applications.
The LM35H consists of a high-parallelism, low-power integrated circuit (IC) with an on-chip amplifier, current source circuit and multiplexer. Its advanced, low-noise, low-offset and low-consumption features make it ideal for high-accuracy, high-dynamic-range measurement applications. For the auto-calibration feature, the LM35H can directly accommodate wide range of input voltage levels and outputs the precision measurement value.
The LM35H is a three-terminal, NPN semiconductor device, which can measure temperatures in the range of -55°C to +125°C. The device operates linearly over a wide temperature range and the 3LeS output is proportional to the temperature within its range. The output of the LM35H can be converted into a digital signal using an A-D converter (ADC). The device offers a variety of options for ADC resolving resolution, accuracy, and power supply range.
LM35H Working Principle
The LM35H operates on the principle of using a NPN transistor as an impedance converter. The circuit consists of a linear, temperature-sensing diode (T), an adjustable, matched NPN current source, (I), and the output (O) which is the difference between the T and I. The differential output signal is at its highest when the diode temperature is at its highest point in its operating range.
The linearity of the LM35H is achieved by a very precise integration of a wideband diode, a low noise current source, and an ADC converter, which provides accurate temperature measurement. The temperature range is wide enough for many applications, and it has low offset and low noise levels. The input and output impedance also provides the flexibility to accommodate for a wide range of circuit configurations.
At the interface between the diode and the I/O circuitry, the amplifying stages are also very sensitive to temperature. This sensing allows for improved accuracy and performance of the overall device. The LM35H is linearized after self-calibration and provides excellent accuracy over its full temperature range.
LM35H Application Field
The LM35H is an excellent choice for a wide variety of applications, from ambient temperature application like room, machine, human and food temperature measurement, to industrial and automotive applications such as weather stations, server rooms, automotive and consumer electronics. It is the ideal choice for applications that require precise, high-accuracy, low-cost, no-hassle temperature measurement.
The output of the LM35H can be connected to a suitable A-D converter in order to obtain temperature information in a digital format. This output can be used to control the temperature of a room or an object with a suitable cooling system. It can also be used for the detection of extreme temperatures and for process control in industrial applications.
The LM35H is also very attractive for automotive applications due to its low power consumption. It is also suitable for use in many small portable devices due its low thermal drift. As a result, it is widely used in portable medical devices, wearable medical sensors, and environmental monitoring systems.
Conclusion
The LM35H is one of the most widely used temperature sensors on the market today due to its excellent accuracy, wide temperature range, and low power consumption. It is suitable for a wide variety of applications such as automotive, industrial, medical, and aerospace applications. The output of the device can be used to detect and regulate temperature in a variety of applications. Its precise, high accuracy, low cost, and no hassle temperature measurement make it the ideal choice for a variety of applications requiring precise and reliable temperature measurements.
