Temperature Sensor IC, Digital, ± 1°C, -55 °C, 150 °C, NSOIC, 8 Pins
Avnet Manufacturer Part #:
ADT7461ARZ-REEL
RoHS 10 Compliant
ADT7461ARZ-REEL 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 3k (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. The ADT7461 can accurately measure the temperature of a remote thermal diode to ±1°C and the ambient temperature to ±3°C. The ADT7461 communicates over a 2-wire serial interface compatible with system management bus (SMBus) standards. Applications include desktop and notebook computers, industrial controllers, smart batteries, embedded systems, instrumentation.
