DS1620S Description

Short technical summary and product information.

The DS1620S from Dallas Semiconductor is a versatile digital thermometer and thermostat designed to add temperature monitoring and control to various systems. It measures temperatures from -55°C to +125°C with a resolution of 0.5°C increments, providing readings as a 9-bit digital value. The device supports a supply voltage range from 2.7V to 5.5V and communicates via a 3-wire serial interface (CLK, DQ, RST).

 

This component requires no external components and is available in an 8-pin SOIC package, making it suitable for space-constrained applications. The DS1620S also features user-definable, nonvolatile thermostatic settings with three thermal alarm outputs (THIGH, TLOW, TCOM), allowing it to function as a thermostat. Its applications span thermostatic controls, industrial systems, consumer products, and thermometers.

 

Key specifications include a temperature sensing range of -55°C to +125°C, a 9-bit resolution, and a maximum conversion time of 750ms. The operating voltage is between 2.7V and 5.5V, and it uses a 3-wire serial interface for data transfer. The device is housed in an 8-SOIC package, suitable for surface mounting.
