Description:

+145c precision smbus-compatible remote/ local sensors.

MAX6646, +145C Precision SMBus-Compatible Remote/ Local Sensors

The MAX6646/MAX6647/MAX6649 are precise, twochannel digital temperature sensors.

The devices accurately measure the temperature of their own die and a remote PN junction, and report the temperature in digital form using a 2-wire serial interface.

The remote PN junction is typically the emitter-base

MAX6646 Features
