MY18 Series Digital Temperature Sensors

Product Overview

The MY18E20, MY1820, MY18B20Z, and MY18B20L are digital mixed-signal temperature sensing chips offering high accuracy without user calibration. Utilizing CMOS semiconductor PN junction temperature and bandgap voltage characteristics, these chips provide precise temperature measurements with advantages like high accuracy, good consistency, low power consumption, flexible programmable configuration, and long lifespan. They feature a built-in 14-bit ADC (defaulting to 12-bit) with a resolution of 0.0125C (0.0625C at 12-bit) and an operating range of -55C to +125C. The chips are 100% tested and calibrated at the factory. Communication is simplified through a single digital bus protocol, requiring only one GPIO port for read/write access. This single-bus interface supports multi-node sensing and networking, enabling cost-effective, long-distance, and high-node-count distributed sensing networks, supporting up to 100 nodes in series over 100-500 meters. Integrated non-volatile E2PROM stores chip ID, alarm thresholds, calibration values, and user-defined information. Available in TO-92, TO92S, SOP8, and TO-92L packages, with the TO-92L offering ESD protection up to 15000V.
