ADT7481 - Dual Channel Temperature Sensor and Over Temperature Alarm
Analog Devices
General Description
The ADT74811 is a 3-channel digital thermometer and under/ over temperature alarm, intended for use in PCs and thermal management systems.
It can measure its own ambient temperature or the temperature of two remote thermal diodes.
Key Features
1 local and 2 remote temperature sensors 0.25°C resolution/1°C accuracy on remote channels 1°C resolution/1°C accuracy on local channel Extended, switchable temperature measurement range 0°C to 127°C (default) or.
64°C to +191°C 2-wire SMBus serial interface with SMBus ALERT support Programmable over/under temperature limits Offset registers for system calibration Up to 2 over temperature fail-safe THERM outputs Small 10-lead MSOP package 240 μA operating current, 5 μA standby current
