Active production, ±3°C system temperature monitor
The ADM1032ARM-1: Accuracy is ±3°C across the 0°C to 100°C test condition — the spec that matters most for a monitor that triggers thermal throttling or fan control. The local sensing range is 0°C to 100°C; the remote channel extends to 0°C to 120°C, covering the junction temperature of most processor cores.
7-bit SMBus output with programmable limits
Resolution is 7 bits, giving 128 discrete temperature steps over the measurement range — sufficient for overtemperature alarm thresholds but not for fine-grained thermal profiling. The output is SMBus-compatible, so it shares a two-wire bus with other SMBus devices without additional address decoding logic. Built-in features include an output switch (ALERT# or THERM# pin), programmable limit registers, and a standby mode that drops the supply current when the system is idle.
Package and compliance — RoHS non-compliant
The ADM1032ARM-1 is supplied in an 8-TSSOP or 8-MSOP package (3.00 mm width) with the Micro8 supplier device package designation. Mounting is surface-mount, and the listed package form is Bulk — not tape-and-reel. The ADM1032ARM-1REEL7 is the functionally identical reel-packaged variant if your pick-and-place line requires reel feed. RoHS status is non-compliant per the lifecycle record. For BOMs that require RoHS compliance, the ADM1032ARMZ-2R-AD (with the 'Z' suffix) is the lead-free alternative — confirm the pinout and register map are identical before substituting.
