2 Channel Electronic Volume 14-Pin SOP T/R

ROHM"s 2ch / 6ch electronic volume ICs feature a wide dynamic range (131dB / 133dB). In addition, two ICs can be paired up via serial bus control for 8ch operation. ·Residual noise : 1.2µVrms {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=10kO)
·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
