BD3460FS-E2

Audio Special Purpose Overview

The BD3460FS-E2 is a 6-channel electronic volume controller manufactured by ROHM Semiconductor. It features an I2C bus interface for digital control and includes 'Advanced Switch' technology to minimize shock noise during channel switching. The device operates on a single power supply of 7 V to 9.5 V with a typical operating current of 25 mA. It offers a volume range of +23 dB to -79 dB (and mute) in 1 dB steps, with a THD+N of 0.0004%. It is housed in a 24-pin SSOP-A package.

Audio Special Purpose Procurement Notes

Verify the 'E2' suffix indicates RoHS compliance and lead-free status as per ROHM standards. Confirm the package is SSOP-A24 (5.4mm width), not standard SSOP. Check availability status on the manufacturer's website as automotive parts may have specific lifecycle notices.

Audio Special Purpose Selection Notes

Select this component when a 6-channel volume controller with low distortion and I2C control is needed. The 'Advanced Switch' feature is critical for applications where audible clicks during source selection are unacceptable. Ensure the system voltage stays within 7V-9.5V. Note that while it is used in automotive applications, verify if AEC-Q100 qualification is required for your specific design; the datasheet lists it as an automotive part but specific grade certification should be confirmed in the latest datasheet.

Audio Special Purpose Part Context

This part belongs to the BD3460FS series of general-purpose electronic volume controllers with advanced switches. It is distinct from the BD3465FV (4-channel) and BD3461FS (8-channel). The BD34602FS-ME2 is a related variant often cited in automotive contexts, but the BD3460FS-E2 is the standard commercial/automotive grade version in the SSOP-A package.
