Sentech T1820/T1820B Digital Temperature Sensor Chip

Product Overview
The Sentech T1820X series are digital-analog mixed-signal temperature sensing chips offering high accuracy up to 0.1 without user calibration. Leveraging CMOS semiconductor PN junction temperature and bandgap voltage characteristics, these chips provide precise, consistent, and fast temperature measurements with low power consumption. They feature a built-in 16-bit ADC with 0.004C resolution and an ultra-wide operating range of -103C to +153C. Each chip is 100% factory tested and calibrated. The digital single-bus protocol (One Wire, OW) simplifies system integration, requiring only one GPIO port for communication. This allows for cost-effective, multi-node sensing networks with long transmission distances, supporting up to 100 nodes in a chain up to 500 meters. Integrated non-volatile E2PROM stores chip ID, alarm thresholds, calibration values, and user-defined information like sensor node ID and location.
