BD3465FV-E2

Audio Special Purpose Overview

The BD3465FV-E2 is a general-purpose electronic volume controller manufactured by ROHM Semiconductor. It features four channels with integrated advanced switches to minimize switching noise during volume adjustments. The device operates on a single power supply ranging from 7 V to 9.5 V and draws a typical quiescent current of 25 mA. It delivers an output voltage of 2.35 V (typical) with a total harmonic distortion plus noise of 0.0004%. The unit is housed in a 20-pin SSOP-B package.

Audio Special Purpose Feature Summary

• Four-channel electronic volume control with integrated advanced switches to reduce click noise
• I2C bus interface for digital control
• Low THD+N of 0.0004% and output noise of 1.9 µVrms
• Volume range of +23 dB to -79 dB with 1 dB steps

Audio Special Purpose Applications

• General audio equipment volume regulation
• Consumer electronics requiring low-noise volume adjustment
• Multi-channel audio processing systems

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix and packaging configuration against the manufacturer's latest datasheet before procurement. Confirm that the 20-SSOP-B package dimensions match the target PCB footprint. Ensure the I2C address settings align with the system design requirements. Check for any end-of-life or obsolescence notices from ROHM Semiconductor.

Audio Special Purpose Selection Notes

Select this component when a four-channel volume controller with low distortion and integrated switch functionality is required. The 7 V to 9.5 V supply range suits standard single-supply audio applications. Compare with the BD3460FS-E2 if six outputs are needed, or the BD34700FV-E2 for different voltage ranges. Verify thermal performance within the -40°C to 85°C operating temperature range.
