PRODUCT FEATURES
Datasheet
General Description
Features
The EMC1072 is a high accuracy, low cost, System
Management Bus (SMBus) temperature sensor with pin
selectable SMBus address.
The device provides ±1° accuracy (max) for external
diode temperatures and ±2°C accuracy (max) for the
internal diode temperature. The EMC1072 monitors two
temperature channels (one external and one internal).
„ Pin Compatible with ADM1032, MAX6649, and LM99
„ External Temperature Monitors
— ±0.25°C typ accuracy (20°C < TDIODE < 110°C)
— 0.125°C resolution
— Supports 2N3904 and AMD diodes
„ Internal Temperature Monitor
— ±0.25°C typ accuracy (-5°C < TA < 100°C)
„ 3.3V Supply Voltage
Applications
„ SMBus 2.0 Compliant
— Programmable SMBus address
„ Notebook Computers
„ Desktop Computers
„ Industrial
„ Embedded applications
„ Programmable Temperature Limits for ALERT and
THERM
„ Available in Small 8-pin MSOP Lead-free RoHS
Compliant Package
