BD3814FV
Audio ICS
High- performance 5.1ch electronic volume
BD3814FV
BD3814FV is a sound processor IC. This IC incorporates volume, bass and treble functions into a single chip that are necessary for AV receivers and mini-component stereos. Low distortion, low noise and wide dynamic range can be achieved by using the Bi-CMOS process.
!Applications
!External dimensions (Unit : mm)
13.6 0.2

AV receiver, mini stereo set and TV.
!Features 1) Dynamic range : 132dB (Tone by-pass, VOL=MUTE, IHF-A) 2) Master volume is 6ch-Independent volume (0~95dB, Mute, 1dB/Step). Low residual noise with Resistor ladder volume and the shock sound in changing is reducing. 3) It is becoming a low consumption electric current design by using the Bi-CMOS process. 4) Maximum output voltage : 4.3Vrms (VCC=7V, VEE= -7V, RL=10k). 5) Built-in two OP amplifiers. 6) Serial data control of 2-wire type (correspond to 3.3V and 5V).
