The DS1621S from Analog Devices / Maxim Integrated is a digital thermometer and thermostat that provides accurate temperature monitoring for various systems. It measures temperatures from -55°C to +125°C with a resolution of 9 bits, allowing for precise readings.
The sensor communicates via a 2-wire serial interface (I²C), simplifying integration into existing designs. It operates within a voltage range of 2.7V to 5.5V and requires no external components for temperature measurements, saving valuable board space. The device features user-definable thermostatic settings stored in non-volatile memory.
Available in an 8-SOIC package, the DS1621S is suitable for surface mount applications. Its features include one-shot operation, an output switch for thermostat functionality, and a standby mode. The accuracy is ±0.5°C typical within the 0°C to 70°C range, with a broader specification of ±2°C across its full operating temperature range.
This digital thermometer is ideal for applications such as thermostatic controls, industrial systems, consumer products, and general-purpose thermometers where reliable temperature monitoring is essential.
