BA7655AF-E2

Overview

The BA7655AF-E2 is a dual voltage-controlled amplifier IC designed for video signal level adjustment in VCR and DVC applications. It features two independent amplifier circuits with adjustable gain ranging from -6 dB to +6 dB via control pin voltage. The device operates within a supply voltage range of 4.5 V to 5.5 V, consuming up to 12 mA across both channels. When the control voltage drops to 1 V or less, the IC enters power save mode, reducing current consumption by approximately 40% and muting the output. It utilizes an SOP-8 package.

Feature Summary

• Dual-channel architecture allowing independent operation of two voltage-controlled amplifiers
• Variable voltage gain capability spanning from -6 dB to +6 dB through external control voltage regulation
• Integrated power save functionality that reduces current draw and mutes outputs when control voltage is low
• Broadband frequency characteristics suitable for high-frequency video signal processing

Applications

• Video cassette recorder (VCR) signal level adjustment
• Digital video camera (DVC) video signal processing
• General-purpose video signal level control circuits

Procurement Notes

Verify the specific ordering suffix E2 corresponds to the embossed tape and reel packaging format containing 2500 pieces per reel. Confirm the SOP-8 package dimensions match the required PCB footprint. Ensure the design accounts for the absolute maximum ratings, particularly the 8.0 V supply limit and thermal derating requirements above 25°C ambient temperature.

Selection Notes

Select this component for designs requiring precise analog video gain control without digital interfaces. The dual-channel configuration supports stereo or composite/signal separation tasks. Consider the input coupling capacitor requirement for DC blocking and verify that the load resistance meets the minimum drivability specifications to maintain signal integrity.

Part Context

This part belongs to ROHM's Video Accessory ICs family, specifically categorized as VCAs for video signal level adjustment. The BA7655AF variant shares functional similarities with the BA7655A but includes specific packaging and environmental compliance markings indicated by the suffixes. It serves as a specialized analog solution for consumer electronics video processing chains.

Replacement Considerations

BA7655A is the base model variant sharing identical electrical functions and block diagrams.
