NTE1576
Integrated Circuit
Dual Volume Control/Balance/Tone
Description:
The NTE1576 is a DC controlled dual volume, balance and tone (Bass, treble) integrated circuit in
1 16–Lead DIP type package. As these dual channels are constructed on one chip, this IC is excellent
in pair characterisitics and it is suitable for automobile stereo, radio cassette, music center, TV multiplex sound receiver and remote controlled applications.
Features:
D Wide Power Supply Voltage Range:
Single Supply VCC (opr) = 8V to 14V
Dual Supply VCC – VEE (opr) = ±4V to ±7V
D Wide Volume Control Range: VR = 80dB (Typ.)
D Excellent Cross Talk: CT = 70dB (Typ)
D Stable for Temperature Drift
D Wide Tone Control Range:
VB = 10dB (Typ) at f = 1kHz 100Hz
VT = 12dB (Typ) at f = 1kHz 20kHz
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
