That covers most indoor equipment, rack-mount gear, and well-ventilated enclosures, but it does not extend to automotive under-hood, outdoor base stations, or downhole tools. For those environments, a part with an extended or industrial temperature range would be needed. ## Package options: 16-SSOP and 16-QSOP Either way, the PCB land pattern is a standard 0.025\" pitch SSOP/QSOP footprint.","metaTitle":"ADM1028ARQ Fan Control, Temp Monitor, SMBus, 16-SSOP","metaDescription":"ADI ADM1028ARQ fan control and temperature monitor IC.
