ADT7461AR

为± 1A ????温度监测器，串联电阻抵消 ±1℃ Temperature Monitor with Series Resistance Cancellation

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.
