BA3308F-E2

Overview

The BA3308F-E2 is a dual preamplifier integrated circuit manufactured by Rohm Semiconductor, designed for audio signal processing applications. It features built-in Automatic Level Control (ALC) circuits to manage input signal dynamics without external components. The device is housed in a 14-LSSOP package with a width of 4.40mm. As an audio preamp, it provides stereo amplification capabilities suitable for consumer electronics.

Feature Summary

• Dual channel preamplifier architecture for stereo audio signals
• Integrated Automatic Level Control (ALC) circuitry
• Monolithic IC design for compact implementation

Applications

• Headphone stereo systems
• Audio recording equipment preamps
• Consumer audio amplifier stages

Procurement Notes

Verify the specific suffix 'E2' against the manufacturer's current datasheet to confirm environmental compliance and pinout compatibility. Ensure the 14-LSSOP package dimensions match the target PCB footprint. Confirm availability status as distribution data may vary by region.

Selection Notes

Select this component when a dual-channel solution with integrated ALC is required to simplify schematic design. It is appropriate for applications needing stereo pre-amplification with automatic gain management. Verify power supply requirements and thermal performance within the LSSOP package constraints before finalizing the design.

Part Context

This part belongs to Rohm's BA series of audio operational amplifiers and preamplifiers. The BA3308F variant specifically targets applications requiring dual-channel amplification with level control. The E2 suffix typically denotes lead-free packaging compliant with RoHS directives, aligning with modern manufacturing standards.

Replacement Considerations

Check for direct substitutes such as the BA3641FV for headphone stereo applications or other dual preamps with ALC from compatible manufacturers. Ensure functional equivalence regarding channel count and ALC integration.
