TA7630P
TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA7630P
Dual. Volume/Balance/Tone (Bass/Treble)
DC Control IC
The TA7630P is DC controlled dual volume, balance, tone (Bass,
treble) IC. As these dual channels are constructed on one chip,
this IC is excellent in pair characteristic.
It is suitable for automobile stereo, radio cassette, music center,
TV multiplex sound receiver and remote controlled applications.
Features
· Wide power supply voltage range:
Single supply VCC (opr) = 8~14 V (Ta = 25°C)
Dual supply VCC − VEE (opr) = ±4~±7 V (Ta = 25°C) Weight: 1.00 g (typ.)
· Wide volume control range: VR = 80dB (typ.)
· Excellent cross talk: C.T. = 70dB (typ.)
· Stable for temperature drift.
· Wide tone control range
Control range:
VB = 10dB (typ.) (f = 1 kHz → 100 Hz)
VT = 12dB (typ.) (f = 1 kHz → 20 kHz)

3. Application circuit using diode at reference terminal
The application circuit using diode between Pin 5 and Pin 12 has the following merits.
(1) When each control terminal is drived by high impedance, the electrolytic capacitor between terminal
5 and GND operates as the back up capacitor, so that the rise time is short at the ON-OFF repetation
of supply voltage.
(2) When the current drain into the each control terminal varies by control voltage, the voltage of
terminal 5 scarcely varies.
It means a stable reference voltage.
