General Description
The MAX6648/MAX6692 are precise, two-channel digital temperature sensors. They 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 junction of a common-collector PNP on a CPU, FPGA, or ASIC.

FEATUREs
♦ Dual Channel: Measures Remote and Local Temperature
♦ 0.125°C Resolution
♦ High Accuracy: ±0.8°C (max) from +25°C to +125°C (Remote), and ±2°C (max) from +60°C to +100°C (Local)
♦ Two Alarm Outputs: ALERT and OVERT
♦ Two Default OVERT Thresholds Available
    MAX6648: +110°C
    MAX6692: +85°C
♦ Programmable Conversion Rate
♦ SMBus-Compatible Interface
♦ SMBus Timeout
♦ Programmable Under/Overtemperature Alarm Thresholds
