MY18E20/MY1820/MY18B20Z/MY18B20L Digital Temperature Sensor ICs
Product Overview
The MY18E20, MY1820, MY18B20Z, and MY18B20L are digital analog mixed-signal temperature sensing chips offering high accuracy without user calibration. Leveraging CMOS semiconductor PN junction temperature characteristics and bandgap voltage, 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 with a resolution of 0.0125C (default 12-bit, 0.0625C resolution) and a wide operating range of -55C to +125C. The chips are 100% tested and calibrated before shipment, with internal automatic compensation. Communication is simplified via a single digital bus protocol, requiring only one GPIO port for microprocessors. This single-bus interface enables cost-effective, multi-node sensing and networking, supporting up to 100 nodes in a series network up to 500 meters long. 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 15000V ESD protection.
