DS18B20U in DS18B20 1-Wire Temperature Family
The DS18B20U sub-family, manufactured by Analog Devices (Maxim Integrated), consists of digital thermometers providing 9-bit to 12-bit Celsius temperature measurements. These sensors communicate over a 1-Wire bus, requiring only one data line and ground for communication with a central microprocessor. The 'U' variant specifically denotes the 8-pin uMAX (uSOP) package, offering a smaller footprint than traditional TO-92 versions, making it ideal for space-constrained industrial and consumer electronics requiring precise thermal monitoring.
Variants in This Sub-Family
Variants within the DS18B20U sub-family primarily differ based on their packaging and delivery format, such as the DS18B20U+ which denotes a lead-free, RoHS-compliant 8-pin uMAX package, and the DS18B20U+T&R which indicates the same component provided on tape and reel for automated SMT assembly. All variants maintain the same electrical characteristics, including the 3.0V to 5.5V operating voltage range and the 64-bit unique serial code stored in on-board ROM.
