BD3813KS/BD3815KS is a 5.1-channel audio processor from ROHM that integrates an amplifier and volume/bass/treble controls, making it ideal for use in audio applications such as AV receivers, home theater systems, and mini-component systems.
The BD3813KS and BD3815KS are semiconductor sound processors designed for AV receivers, home theater and mini‑component systems. They integrate a gain amplifier and independent volume, bass and treble controls, enabling 6.1‑ch or 7.1‑ch operation when used with the BD3812F volume IC.
Key features include a 129 dB dynamic range, low current consumption, a maximum output of 4.2 Vrms, and a 2‑wire serial control interface. The devices are supplied in an SQFP56 package and operate from a ±7 V supply.
