MAX6657MSA Datasheet PDF - Maxim Integrated

General Description

●The MAX6657/MAX6658/MAX6659 are precise, two channel digital temperature sensors. Each accurately measures the temperature of its own die and one remote PN junction, and reports the temperature in digi tal form on a 2-wire serial interface. The remote junction can be a diode-connected transistor like the low-cost NPN type 2N3904 or 2N3906 PNP type. The remote junction can also be a common-collector PNP, such as a substrate PNP of a microprocessor.
