ADT7461数据手册传感器变送器的温度传感器-模拟数字输出规格书PDF

描述 Description

The ADT7461 is a dual-channel digital thermometer and under/over temperature alarm intended for use in PCs and thermal management systems. It is pin- and register-compatible with the ADM1032. The ADT7461 has three additional features: series resistance cancellation (where up to 3 kΩ (typical) of resistance in series with the temperature monitoring diode may be automatically cancelled from the temperature result, allowing noise filtering); configurable ~ALERT output; and an extended, switchable temperature measurement range.

特性 Features

• On-chip and Remote Temperature Sensor
• 0.25°C Resolution/1°C Accuracy on Remote Channel
• 1°C Resolution/3°C Accuracy on Local Channel
• Automatically Cancels up to 3 kΩ (typical) of Resistance in Series with Remote Diode to Allow Noise Filtering
• 2-wire SMBus Serial Interface with SMBus Alert Support
• Programmable Over/Under Temperature Limits
• Up to Two Over Temperature Fail-safe THERM Outputs
• 170 µA Operating Current, 5.5 µA Standby Current

应用 Application

• Thermal Management
• Notebook and Desktop Computers
• Game Consoles
• RFID Readers
• DSL Line Cards
