A 7V to 9.5V range means the part expects a regulated 8V or 9V rail — not a raw battery bus or a 12V automotive line. If your board carries a 5V-only rail, you need a boost or a separate LDO. The 3-channel count confirms it can process left, right, and subwoofer or centre channels independently. ## Package and footprint — 32-SOP (0.213\" body) The BD37543FS- comes in a 32-SOP package with a 5.40mm body width (0.213\") and is also designated as 32-SSOP-A by ROHM. Surface-mount only. The narrow body means the pad pitch is tighter than a standard SOP — verify your PCB land pattern against the ROHM mechanical drawing before committing the layout. Tape & Reel and Cut Tape options are available for ordering. For production BOMs that require a fully compliant part, the ROHS3 rating covers the current regulatory baseline without a transition risk.","metaTitle":"BD37543FS-E2 Audio Tone Processor, 7V-9.5V, 32-SOP","metaDescription":"ROHM BD37543FS-E2 Audio Tone Processor for automotive audio. 3-channel, 7V-9.5V supply, -40°C to 85°C, 32-SOP package.
