MIC281 Datasheet (Micrel Semiconductor)

MIC281, Thermal Sensor

The MIC281 is a digital thermal sensor capable of measuring the temperature of a remote PN junction.

It is optimized for applications favoring low cost and small size.

The remote junction may be an inexpensive commodity transistor, e.g., 2N3906, or an embedded thermal diode such as found in Intel Pe

MIC281 Features

* the same industry-leading noise performance and small size. The advanced integrating A/D converter and analog front-end reduce errors due to noise for maximum accuracy and minimum guardbanding. A 2-wire SMBus 2.0-compatible serial interface is provided for host communication. The clock and data pins
