STMicroelectronics LM235Z Precision Temperature Sensor
The LM235Z is a precision temperature sensor from STMicroelectronics, designed to measure temperature with high accuracy and reliability. This versatile device can be employed in a wide range of applications, from industrial systems to consumer electronics, thanks to its robust design and straightforward interfacing with reading circuits.
At the heart of the LM235Z is a temperature-sensing element that provides a linearly proportional voltage output to the temperature it measures. The sensor operates over a wide temperature range of -55°C to +150°C, making it suitable for environments that experience extreme temperature conditions. The output voltage of the LM235Z changes by 10 mV/°C, which allows for easy conversion from voltage to temperature without requiring complex calculations.
The LM235Z comes in a TO-92 package, a widely used through-hole mounting design that ensures compatibility with various PCB layouts and simplifies the assembly process. This package is known for its durability and is capable of withstanding harsh conditions, which is essential for maintaining the integrity of temperature measurements in challenging environments.
One of the key features of the LM235Z is its excellent stability over time. The sensor's output remains consistent, ensuring that temperature readings remain accurate even after prolonged use. This long-term stability is critical for applications that require dependable and precise temperature monitoring over the lifespan of the device.
Furthermore, the LM235Z requires no external calibration or trimming to provide typical accuracies of ±1°C at room temperature and ±2°C over the full -55°C to +150°C temperature range. The simplicity of its interface and the minimal external components needed make it an ideal choice for designers looking to incorporate temperature sensing into their projects with minimal hassle.
Users can also benefit from the sensor's low operating current, which is less than 60 µA, making the LM235Z an energy-efficient component in battery-powered applications. With its high precision, low power consumption, and ease of use, the LM235Z from STMicroelectronics stands out as a top choice for temperature sensing solutions across various industries.
