Temperature Sensor IC with High Speed I2C Interface and Self Diagnostic Heating Chip Mysentech MTS4P

MTS4/MTS4B Series Digital Temperature Sensor IC

The MTS4 series are digital-analog mixed-signal temperature sensor ICs offering high accuracy 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 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, with internal automatic compensation. The I2C interface supports high-speed board-level applications up to 1MHz. Built-in non-volatile E2PROM stores chip ID, alarm thresholds, calibration data, and user-defined information like sensor node numbers and location.
