ROHM Semiconductor BD34602FS-M 6-channel Sound Processors
ROHM Semiconductor BD34602FS-M 6-channel Sound Processors are AEC-Q100-qualified sound processors IC designed for high-quality automotive audio applications. The BD34602FS-M features a 6-channel independent volume control and an advanced switch circuit to reduce switching noise during volume attenuation. Integrated 3-channel attenuation, which can be controlled independently, is provided for external sound mixing. This option enables seamless mixing of entertainment audio and vehicle navigation sound.
The ROHM Semiconductor BD34602FS-M is offered in a compact SSOP-A24 with I/O terminal designations optimized for PCB layout, making it ideal for space-constrained applications.
