Active production — I²C volume control for multi-channel audio
The BD3464FV-E2: The BD3464FV- is an active-production I²C-controlled 6-channel volume control IC from ROHM Semiconductor, housed in a 20-LSSOP (4.40mm width) surface-mount package. It targets automotive and consumer audio applications where a single IC manages multiple audio zones or channels with digital precision.
Supply and temperature range — automotive cabin and consumer gear
Operating from 7V to 9.5V, the BD3464FV- fits common 8V and 9V audio rails. The -109dB specification (likely dynamic range or noise floor) indicates low-noise performance suitable for high-fidelity signal paths — a figure that matters when the volume control stage must not degrade the upstream DAC's SNR.
Package and compliance — 20-LSSOP, ROHS3
The 20-LSSOP (0.173", 4.40mm width) package with supplier device package 20-SSOP-B is a standard fine-pitch surface-mount footprint. ROHS3 compliant — no exemptions for lead, mercury, or other restricted substances, simplifying global market entry.
