PRODUCT FEATURES

General Description

Features

External Temperature Monitors

The EMC1073 and EMC1074 are high accuracy, low

cost, System Management Bus (SMBus) temperature

sensors with pin selectable SMBus addresses.

—

±0.25°C typ accuracy (20°C < T_DIODE< 110°C)

0.125°C resolution

Supports 2N3904 and AMD diodes

Anti-parallel diodes for extra diode support (EMC1074)

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).

Internal Temperature Monitor

—

±0.25°C typ accuracy (-5°C < T_A< 100°C)

3.3V Supply Voltage

SMBus 2.0 Compliant

—

Programmable SMBus address
