ROHM Semiconductor USA, LLC Audio Special Purpose - BD3814FV-E2 BD3814FV-E2

BD3814FV-E2 is a 1-chip sound processor designed for applications in AV receivers, home theater systems, and mini-audio systems. It features six independent channels for master volume control, with a range from 0 to -95 dB and a mute function at 1 dB steps. The device utilizes a Bi-CMOS process, ensuring low distortion and noise levels, with a dynamic range of 132 dB when the volume is muted. The maximum output voltage is 4.3 Vrms, making it suitable for driving various audio loads. The processor includes built-in operational amplifiers and supports 2-line serial control compatible with both 3.3V and 5V systems. It operates within a power supply voltage range of 5V to 7.5V for VCC and -7.3V to -5V for VEE, with a maximum power dissipation of 900 mW. The operating temperature range is from -20¬8C to +75¬8C, and it is sensitive to electrostatic discharge, requiring proper handling during manufacturing and storage. This product is ideal for engineers looking for a compact and efficient audio processing solution for their audio systems.
