Temperature Range : 0℃~+70℃
Interface : Single-bus
Voltage - Supply : 1.8V~5.5V
Description : 0℃~+70℃ Single-bus 1.8V~5.5V SOP-8 Analog and Digital Output RoHS
Mfr. Part # : DS18B20ZD10-15(MY)
Model Number : DS18B20ZD10-15(MY)
Package : SOP-8
The MYDS18B20 series is a mixed-signal digital temperature sensor chip offering high accuracy without user calibration. Utilizing CMOS semiconductor PN junction temperature characteristics and bandgap voltage, it provides precise temperature readings from -10C to +85C with a typical accuracy of 0.5C. The chip features a 14-bit ADC with a resolution of 0.0125C (defaulting to 12-bit at 0.0625C resolution) and operates across a wide temperature range of -55C to +125C. Its digital single-bus protocol simplifies system integration, requiring only one GPIO port for communication and enabling cost-effective, multi-node sensing networks with long transmission distances. Built-in non-volatile E2PROM stores device ID, alarm thresholds, calibration data, and user-defined information. Available in TO-92, TO-92S, SOP8, and MSOP8 packages.
