Selectable Address
PRODUCT FEATURES
Data Brief
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
