It integrates an ADC, comparator, multiplexer, and register bank in a single 16-pin SSOP or QSOP package, so a single IC replaces several discrete temperature sensors and fan-control logic blocks on a server, telecom line card, or industrial controller PCB.
The ADM1034ARQ communicates over SMBus. The output alarm pin provides a hardware interrupt on over-temperature events.
Yes. The output type is SMBus, and the part includes an SMBus-compatible serial interface. The alarm output provides a hardware interrupt on over-temperature events, so the host does not need to poll the register bank continuously.
Yes. The supply voltage range is 3V to 5.5V, so a 3.3V rail is within spec. The part will operate on the same 3.3V SMBus without an additional regulator.
±1°C across the full -40°C to 125°C operating range. This covers both the internal sensor and the external diode-connected transistor input.
