The typical application circuit for LM335H is a simple voltage divider circuit with a 1 kΩ to 10 kΩ resistor connected between the output pin and ground, and a 1 μF to 10 μF capacitor connected between the output pin and ground to filter out noise.
The LM335H has an accuracy of ±1°C over the temperature range of -40°C to 100°C, and ±2°C over the temperature range of -50°C to 150°C.
The LM335H has a self-heating effect of approximately 0.1°C to 0.5°C per milliamp of output current, which can affect the accuracy of the temperature measurement. To minimize self-heating, it is recommended to use a low output current and a high impedance load.
Yes, the LM335H can be used in high-temperature applications up to 150°C, but it is recommended to derate the output current and voltage to prevent overheating and ensure reliable operation.
The LM335H can be calibrated by comparing its output voltage to a known temperature reference point, such as an ice bath or a temperature-controlled oven. The calibration process involves adjusting the output voltage to match the known temperature reference point.
