Product Overview

The MYDS18B20 series is a digital mixed-signal temperature sensing chip offering high accuracy and ease of use. It features a measurement accuracy of 0.5C within the -10C to +85C range, eliminating the need for user calibration. Based on CMOS semiconductor PN junction temperature and bandgap voltage characteristics, it provides high precision, good consistency, low power consumption, flexible programmable configuration, and a long lifespan. The chip integrates a 14-bit ADC with a resolution of 0.0125C, with a default factory configuration of 12-bit ADC and an operating range of -55C to +125C. Each chip is 100% tested and calibrated at the factory. Its digital single-bus protocol simplifies system integration, requiring only one GPIO port for microprocessors to access ID search, temperature data memory, and function configuration. The single-bus interface supports low-cost, multi-node sensing and networking solutions with long transmission distances and a high number of supported nodes, up to 100 nodes in series over 100 to 500 meters. The chip includes non-volatile E2PROM for storing ID numbers, high/low temperature alarm thresholds, calibration coefficients, and user-defined information. Available in TO-92, TO-92S, SOP8, and MSOP8 packages.
