The DS1621 from Analog Devices is a digital thermometer and thermostat that provides precise temperature readings. It measures temperatures from -55°C to +125°C with an accuracy of ±0.5°C within the 0°C to 70°C range. The device offers a 9-bit resolution, converting temperature to a digital word in less than one second.
Designed for versatility, the DS1621 operates within a power supply range of 2.7V to 5.5V and utilizes a 2-wire serial interface for data communication. Its thermostat function allows for user-definable temperature settings stored in nonvolatile memory, with an active output signal (TOUT) that triggers when the temperature exceeds a user-defined threshold (TH) and resets when it drops below another threshold (TL), enabling hysteresis.
This sensor requires no external components for temperature measurements, saving valuable board space. It is available in an 8-pin DIP package, suitable for through-hole mounting. The DS1621 is well-suited for applications such as thermostatic controls, industrial systems, consumer products, and thermometers.
