AD592 Precision IC Temperature Transducer (TO-92)

The AD592 is a high-performance, monolithic IC temperature transducer that provides an output current directly proportional to absolute temperature. Designed for simplicity and accuracy, this device acts as a high impedance constant current source, making it highly resistant to electrical noise and voltage fluctuations over long distances. With a calibrated sensitivity of 1 microamp per Kelvin, it allows for easy interfacing with analog-to-digital converters and microcontrollers without complex signal conditioning. The AD592 is particularly well-suited for applications where space is limited and reliability is paramount. Its pre-calibrated nature eliminates the need for external trimming in most cases, making it a cost-effective solution for environmental monitoring, industrial automation, and HVAC system control.

Key Features:

Operating temperature range from -25 to +105 degrees Celsius.

Excellent linearity with minimal error over the full range.

Two-wire connection simplifies remote sensing applications.

High impedance output minimizes effects of voltage drops over long leads.

Minimal self-heating error due to low power dissipation.
