Introduction

BD3812F is an electronic volume having volume, gain amplifier functions necessary for applications in AV receivers, home theatre systems, min-component systems and so forth. Having a chip select terminal, it can be controlled until 4 chips with common bus line.

Features

• Residual noise: 1.2μV rms {dynamic range: 131dB (IHF - A)}
• 2ch independent volume (0 to -103dB, MUTE 1dB/step)
• 8ch at maximum available in combination of any of BD3811K1, BD3813KS, BD3814FV, BD3815KS (6ch volume) in common bus line
• It can be controlled until 4 chips with common bus line at the same time
• Maximum output voltage: 4.2Vrms (Vcc = 7, VEE = -7V, RL = 10kΩ)
• 2 - line serial control (for both 3.3V and 5V)
• Built - in Output gain amplifier for adjustment of output signal voltage (0, 6 to 18dB, 2dB/step)
• Output mute controllable by serial data and external control terminal

Applications

• AV receivers
• home theater systems
• mini - component systems
