ADT7461A: Temperature Sensor with Series Resistance Cancellation

内容: The ADT7461A is a dual-channel digital thermometer...
  • The ADT7461A is a dual-channel digital thermometer and undertemperature/overtemperature alarm, intended for use in PCs and thermal management systems. It is pin- and register-compatible with the ADM1032 and the ADT7461. A feature of the ADT7461A is series resistance cancellation, where up to 1.5 kΩ (typical) of resistance in series with the temperature monitoring diode can be automatically cancelled from the temperature result, allowing noise filtering.
  • 特長
  • On-chip and remote temperature sensor
  • 0.25°C resolution/1°C accuracy on remote channel
  • 1°C resolution/1°C accuracy on local channel
  • Automatically cancels up to 1.5 kΩ (typical) of resistance in series with remote diode to allow noise filtering
  • Extended, switchable temperature measurement range 0°C to +127°C (default) or 64°C to +191°C
  • Pin- and register-compatible with ADM1032 and ADT7461
  • 2-wire SMBus serial interface with SMBus alert support
