EMC1074

EMC1073 / EMC1074 Multiple Channel 1°C Temperature Sensors with Selectable Address PRODUCT FEATURES Datasheet General Description The EMC1073 and EMC1074 are high accuracy, low cost, System Management Bus (SMBus) temperature sensors with pin selectable SMBus addresses. Each device provides ±1° accuracy (max) for external diode temperatures and ±2°C accuracy (max) for the internal diode temperature. The EMC1073 monitors three temperature channels (two external and one internal). The EMC1074 monitors four temperature channels (three external and one internal). Applications „ Notebook Computers „ Desktop Computers „ Industrial „ Embedded applications Features „ External Temperature Monitors — ±0.25°C typ accuracy (20°C < TDIODE < 110°C) — 0.125°C resolution — Supports 2N3904 and AMD diodes — Anti-parallel diodes for extra diode support (EMC1074) „ Internal Temperature Monitor — ±0.25°C typ accuracy (-5°C < TA < 100°C) „ 3.3V Supply Voltage „ SMBus 2.0 ...
