ON ADM1034ARQH-REEL

Overview

The ADM1034ARQ-REEL is a dual-channel remote- and local-temperature sensor and fan controller. The remote channels monitor the temperature of two remote thermal diodes, which may be discrete 2N3904/6s or may be located on a microprocessor die. The device also monitors its own ambient temperature.
