ADT75ARMZ Datasheet

Temperature Sensor


The ADT75ARMZ is a 12-bit digital temperature sensor with the 12th bit acting as the sign bit. An on-board temperature sensor generates a voltage precisely proportional to absolute temperature that is compared to an internal voltage reference and input to a precision digital modulator. Overall accuracy for the ADT75 A Grade is ±2°C from -25°C to +100°C and accuracy for the ADT75 B Grade is ±1°C from 0°C to +70°C. Both grades have excellent transducer linearity. The serial interface is SMBus /I2C- compatible and the open-drain output of the ADT75 is capable of sinking 3 mA.
