BA3884F-E2

Audio Special Purpose Overview

The BA3884F-E2 is an audio signal processor IC manufactured by Rohm Semiconductor. It performs phase and harmonic compensation on audio signals to accurately reproduce the 'rise' section of audio signals, ensuring natural sound reproduction. The device operates within a supply voltage range of 5.4V to 12.3V and supports an operating temperature range of -40°C to 85°C (TA). It features a 2-channel analog interface and is housed in a 24-SOP surface-mount package.

Audio Special Purpose Feature Summary

• Corrects distortion in the rising section of audio signals caused by speaker-amplifier mismatches.
• Adjustable clarity via DC control for compatibility with various speakers and sources.
• Selectable processor or bypass mode controlled by DC voltage.
• Bass boost adjustment via DC control to balance upper frequencies.

Audio Special Purpose Applications

• Component stereo systems
• Car stereo systems
• Radio cassette players
• Televisions
• Multimedia PCs

Audio Special Purpose Procurement Notes

Verify RoHS compliance and lead times through authorized distributors. Confirm the specific suffix E2 indicates tape and reel packaging. Ensure BBE Sound Inc. licensing requirements are met for commercial production.

Audio Special Purpose Selection Notes

Select this component for applications requiring faithful reproduction of audio attack sections. Ensure the design accommodates the 5.4V to 12.3V supply range and utilizes external capacitors C1 and C2 to define treble cutoff frequencies.

Audio Special Purpose Part Context

This part belongs to the BA3884F/S series of sound processors. It is designed to treat the amplifier and speakers as a total audio system, processing signals at the amplifier input stage to minimize phase shift and amplitude distortion.

Audio Special Purpose Replacement Considerations

BA3884F is the non-reel variant of this component. Verify pinout and electrical characteristics match before substitution.

Audio Special Purpose FAQ

How does the BA3884F-E2 correct audio distortion?

It separates the signal into bass, middle, and treble regions, applying phase shifts (-180° and -360°) to middle and treble bands relative to bass to minimize rising section distortion.

What controls the bass boost function?

The amount of bass boost is determined by the DC level applied to the CTL2 pin.

Is a license required to use this IC?

Yes, the IC is manufactured under license from BBE Sound Inc., and a license agreement is required for its use.
