Product Introduction

Digital Temperature Sensor Chip - MTS01B is a high-precision digital-analog mixed-signal temperatureSensor chip,relativelyHigh temperature measurement accuracy of ±0.5°C in the range of 0°C to +50°C0.5°C, requiring no user calibration.The temperature sensing principle of the temperature chip is based on the relationship between CMOS semiconductor PN junction temperature andThe characteristic relationship of bandgap voltage, after small-signal amplification, analog-to-digital conversion,Digital calibration and compensation, then digital bus output, with high accuracy, goodGood consistency, fast temperature measurement, low power consumption, flexible programmable configuration, longLong lifespan, etc.

The temperature chip has a built-in 16-bit ADC with a resolution of 0.004°C andUltra-wide operating range from -70°C to +150°C. The chip undergoes factoryPassed 100% test calibration, calibrated according to temperature error characteristicsCoefficient fitting, with automatic compensation calculation performed internally by the chip. The chip supportsSupports digital single bus and I2C dual communication interface: single bus is suitable for long linesCables, multi-node distributed sensing application scenarios,relativelySupports up to 100Temperature measurement nodes connected in series in a network of 100 to 500 meters long. ChipHas a unique 64-bit ID serial number, chip ID search, measurementTemperature data memory access, function configuration, etc., can all be done through digital single busProtocol commands are implemented, and the host microprocessor only needs one GPIOPort can be accessed for read and writeI2C interface is suitable for high-speed board-levelApplication scenarios,relativelyMaximum interface speed up to 400kHz.

Built-in non-volatile E2PROM storage unit for saving chipChip ID number, high/low temperature alarm thresholds, temperature calibration correction values, and userUser-defined information, such as sensor node number, location information, etc.The chip also has an ALERT alarm indication pin, making it convenient for users to expand hardwareAlarm applications.
