The LM335AZ#ST is an analog temperature sensor, designed and manufactured by STMicroelectronics. It operates over a temperature range of -40°C to +100°C and comes encapsulated in a TO92-3 package. This precision temperature sensor functions as a two-terminal zener, where the voltage across the device has a linear dependence on the absolute temperature at a rate of 10mV/°K. The simplicity of its form factor and the ease of interfacing with reading circuitries, such as analog-to-digital converters, make the LM335AZ#ST an optimal choice for environmental monitoring, HVAC systems, and thermal protection circuits in a variety of commercial and industrial applications. Its ability to provide direct, linear temperature measurement without the need for external calibration, ensures accuracy and simplicity in temperature sensing applications.
