Key Features

  • 1) Independent 6 channels for Master Volume (0 to -103dB, 1dB/Step, MUTE, BD3811K1) (0 to -95dB 1dB/Step, MUTE, BD3818KS) Implementation of a resistance ladder type circuit reduces residual noise and a shock sound at switching. 2) Low current consumption design achieved by adopting the BiCMOS process 3) Maximum output voltage (BD3818KS): 4.3Vrms (Vcc=7V, VEE=-7V, RL=10kΩ) Maximum output voltage (BD3811K1): 4.2Vrms (Vcc=7V, VEE=-7V, RL=10kΩ) 4) Built-in Input Gain Amp useful for adjusting the ou.
