MAX6657 Datasheet (Maxim) - SMBus-Compatible Remote/Local Temperature Sensors

MAX6657, SMBus-Compatible Remote/Local Temperature Sensors

The MAX6657/MAX6658/MAX6659 are precise, twochannel digital temperature sensors.

Each accurately measures the temperature of its own die and one remote PN junction, and reports the temperature in digital form on a 2-wire serial interface.

The remote junction can be a diode-connected transistor like
