AD590LH

The AD590LH is a two-terminal integrated circuit temperature transducer that produces an output current proportional to absolute temperature. It is designed for ease of use, particularly in applications requiring remote or distributed temperature sensing. With its linear current output of 1 µA per Kelvin, the AD590LH simplifies interfacing and calibration compared to voltage-output temperature sensors. It requires no additional components for operation and functions over a wide temperature range. The device exhibits high accuracy and stability, with minimal self-heating effects due to its low current operation. The AD590LH is housed in a hermetic metal can package, which provides robust protection in harsh environments. It is commonly used in industrial, scientific, and medical applications where precise temperature measurement is crucial. Its simplicity, reliability, and durability make it an attractive choice for engineers and designers looking to implement efficient temperature sensing solutions.

The AD590LH is a 2-pin integrated circuit used as a temperature transducer. Its primary function is to produce an output current that is directly proportional to the absolute temperature in Kelvin. The device typically outputs 1 microampere per Kelvin, making it easy to convert the output to a temperature reading. The two pins are designated as follows:
1. Pin 1 (Vsupply/Positive Supply): This pin is connected to a positive DC voltage supply. The typical operating voltage range is between 4V and 30V.
2. Pin 2 (Output/Ground): This pin serves as both the output and the ground connection. The current flowing through this pin represents the temperature reading, with 298.2 microamperes corresponding to 298.2 Kelvin (25°C).
The simplicity of the 2-pin configuration allows the AD590LH to be easily integrated into various applications requiring temperature measurement, such as HVAC systems, process control, and environmental monitoring.
