SGM452B Low Power Digital Temperature Sensor with Thermal Watchdog GENERAL DESCRIPTION The SGM452B is an industry standard digital temperature sensor which integrates sigma-delta analog-to-digital converter (ADC) and I2C interface. This device is accurate to ±1.2℃ (MAX) in the range of -55℃ to +125℃. The SGM452B offers 12-bit digital temperature readings. The power supply voltage of the device is from 2.7V to 5.5V. I2C interface is used to communicate with SGM452B devices and it operates up to 400kHz. There are three address pins of the devices to support eight SGM452B at most on the same I2C bus. There is an appropriative over-temperature output with programmable limit and hysteresis on SGM452B.
