Sound Processors for Home Theater Systems 2ch Electronic Volume BD3812F ● Description 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 1) Residual noise : 1.2µVrms {dynamic range : 131dB (IHF-A)} 2) 2ch independent volume (0 to -103dB, MUTE 1dB/step) 3) 8ch at maximum available in combination of any of BD3811K1, BD3813KS, BD3814FV, BD3815KS (6ch volume) in common bus line 4) It can be controlled until 4 chips with common bus line at the same time 5) Maximum output voltage : 4.2Vrms (Vcc=7, VEE=-7V, RL=10kΩ) 6) 2-line serial control (for both 3.3V and 5V) 7) Built-in Output gain amplifier for adjustment of output signal voltage (0, 6 to 18dB, 2dB/step) 8) Output mute controllable by serial data and external control terminal ● Applications AV receivers, home theater systems, mini-component systems, etc. ● Absolute maximum ratings (Ta=25℃) Parameter Symbol Ratings Unit Powewr supply voltage VCC 7.5 *1 V VEE -7.5 Input signal voltage VIN VCC+0.3 to VEE-0.3 V Power dissipation Pd 450 *2 mW Operating temperature range Topr - 20 to +75 ℃ Storage temperature range Tastg - 55 to +125 ℃ *1 Even in the specified range of Power Supply Voltage, applying voltage only to the VCC side may cause an excessive current to give a permanent damage to the IC. When starting up power supplies, VEE and VCC should be powered on simultaneously or VEE first; then followed by VCC. *2 Over Ta=25°C, reduce at the rate of 4.5mW/°C. When installed on the standard board (size: 70x70x1.6mm). ● Operating conditions It must function normally at Ta=25°C. Parameter Symbol Ratings Unit Min. Typ. Max. Operating source voltage VCC 5 7 7.3 V VEE -7.3 -7 -5 No.10081EAT03 |
