The commercial temperature grade means it should not be specified for automotive under-hood, outdoor base stations, or industrial enclosures without active cooling. Housed in a 24-lead SSOP (3.90 mm width) — also referred to as a 24-QSOP in the supplier device package field. Surface-mount, standard pitch, no thermal pad required. The bulk shipping form (tube or tray) is fine for prototype and low-volume builds; for production reels, the ADM1029ARQ-REEL7 variant uses the same die and layout. ## RoHS status — plan for it The ADM1029ARQ is marked RoHS non-compliant. If your BOM requires RoHS exemption (e.g., lead in solder joints for high-reliability applications), this part may still be acceptable under certain exemptions. For standard EU or China RoHS compliance, you will need to source a lead-free alternate or confirm an exemption applies.","metaTitle":"ADM1029ARQ Fan Controller & Temp Monitor","metaDescription":"ADI ADM1029ARQ dual PWM fan controller with ±1°C local, ±3°C remote accuracy.

For a tighter remote accuracy (±0.5°C) and SMBus output instead of open-drain, the ADM1031ARQ-REEL is a functional upgrade, but verify the interface change (SMBus vs open-drain) against your fan driver circuit."},{"question":"What is the accuracy of ADM1029ARQ?","answer":"Local sensor accuracy is ±1°C; remote sensor accuracy is ±3°C. The remote channel reads an external diode-connected transistor, so the ±3°C spec includes the diode tolerance — for tighter control, use the local reading or the ADM1031 variant with ±0.5°C remote."},{"question":"Is ADM1029ARQ available via RFQ confirmation?","answer":"Stock levels and lead times are confirmed at quote time.
