DS1621+ Description

Short technical summary and product information.

The DS1621+ is a digital thermometer and thermostat from Analog Devices / Maxim Integrated. It offers precise temperature monitoring and control for various applications.

 

This sensor measures temperatures across a wide range, from -55°C to +125°C, with an accuracy of ±0.5°C within the 0°C to 70°C range and ±2°C across the full operating spectrum. Temperature readings are provided as a 9-bit digital value, convertible in under one second. The device communicates via a simple 2-wire serial interface, requiring only 2.7V to 5.5V of power and no external components for temperature measurement.

 

Key features include user-definable, non-volatile thermostatic settings. The TOUT pin activates when the temperature exceeds a user-defined high threshold (TH) and resets when it drops below a user-defined low threshold (TL), allowing for hysteresis. This makes it suitable for thermostatic controls and systems requiring temperature-based alerts.

 

The DS1621+ is available in an 8-pin DIP (300 mil) package and is designed for through-hole mounting. Its compact design and integrated functionality save space and simplify system design.
