• Temperature Sensors - Analog and Digital Output
• LM335AH Application Field and Working Principle

The LM335AH is a temperature sensor that operates on a voltage output to measure temperatures in analog output mode. It is an integrated analog semiconductor with an integrated temperature sensor and a reference voltage source. The LM335AH is capable of directly measuring temperatures, enabling precise temperature measurement with little error. The device is readily available and cost-effective, making it ideal for automotive, industrial, consumer, and telecom applications.

The LM335AH provides an accurate temperature output that is easy and quick to adjust and is compatible with both analog and digital input devices. The rugged ceramic package makes the device highly resistant to shocks, both physical and electrical. Furthermore, the device is also resistant to weathering and provides improved accuracy over temperature and aging. Additionally, the device has low power consumption and a high level of immunity to electrical noise.

The working principle of the LM335AH is based on the temperature-dependent thermistor principle. When the voltage applied to the device is held constant, a voltage proportional to the temperature of its junction is generated. This voltage is further amplified and converted into an analog signal representative of the measured temperature. The LM335AH measures temperatures ranging from -55°C to +150°C which is suitable for most temperature measurement applications.

The LM335AH\'s integration of the temperature sensor and voltage reference makes it well-suited for a variety of applications. These applications include, but are not limited to, temperature sensing, water and oil levels, humidity measurement, and airflow rate measurements. Additionally, the device can be used for thermopile measurements, personal computer hardware temperature control, air conditioner control, gas control and monitoring, voltage stabilizer, and soil resistance measurements. The LM335AH can also be used in safety systems such as in lofts, greenhouses, and hobby stores.

The LM335AH is an extremely versatile and easy-to-use temperature measurement device that is suitable for a wide variety of applications. Its high accuracy and low current requirements make it a reliable and cost-effective solution for many temperature measurement applications.
