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)
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 (V
CC
=7V, V
EE
= -7V, RL=10kΩ).
5) Built-in two OP amplifiers.
6) Serial data control of 2-wire type (correspond to 3.3V and 5V).
