BA3823LS

Audio Special Purpose Overview

The BA3823LS is a monolithic five-point stereo graphic equalizer integrated circuit manufactured by Rohm Semiconductor. It integrates two channels with independently adjustable center frequencies using external capacitors. The device operates within a supply voltage range of 3.5V to 14V and features excellent ripple rejection capabilities, allowing the omission of external ripple filter components. The component is housed in a 24-SZIP (formed leads) package suitable for through-hole mounting.

Audio Special Purpose Feature Summary

• Integrates a complete five-point stereo graphic equalizer in a single IC
• Wide operating power supply voltage range from 3.5V to 14V
• Excellent internal ripple rejection eliminates the need for external ripple filters

Audio Special Purpose Applications

• Five-point stereo graphic equalizers for home stereo systems
• Audio processing in radio cassette players
• Graphic equalization circuits for car stereos

Audio Special Purpose Procurement Notes

This product is discontinued (EOL). Verify availability with distributors as stock may be limited or exhausted. Confirm that the 24-SZIP package aligns with the target PCB footprint requirements.

Audio Special Purpose Selection Notes

Select the BA3823LS when high ripple rejection is required to simplify the circuit design by removing external filtering components. Ensure the application utilizes external capacitors to set the five center frequencies per channel. Compare the specific gain control range against the BA3822LS or BA3824LS if different boost/cut specifications are needed for the audio system.

Audio Special Purpose Part Context

The BA3823LS belongs to a family of monolithic five-channel stereo graphic equalizer ICs produced by Rohm Semiconductor. This series includes variants such as the BA3822LS, BA3822FS, and BA3824LS. While all share the same core architecture and pinout, they differ in their specific control range gains.

Audio Special Purpose Replacement Considerations

The BA3822LS, BA3822FS, and BA3824LS are functionally similar members of the same family. Substitution requires verifying that the alternative part's specific control range gain matches the original circuit design requirements.
