TA7666P

The TA7666P includes two inverting amplifiers, ten comparators and a reference voltage network. Turn-on level invervals are 5 dB, 5 dB, 3 dB, 3 dB in the device. It is suitable for stereo radio cassette applications because of dual type.

There are some features as follows: (1)suitable for stereo LED driver; (2)wide supply voltage range: VCC=6 to 12 V; (3)low quiscent current: ICCQ=4 mA typ at VCC=9 V; (4)variable voltage gain because of inverting amplifier; (5)easy arrangement for dual 10 LED's driver by series connection of TA7666P.

What comes next is about the maximum ratings (TA=25) of the TA7666P: (1)supply voltage, VCC: 14 V; (2)output current, IO: 30 mA; (3)LED drive terminal voltage, VL: 15 V; (4)power dissipation, PD: 750 mW; (5)operating temperature, Topr: -30 to 75; (6)storage temperature, Tstg: -55 to 150.

The last one of the TA7666P is about the electrical characteristics (unless otherwise specified, VCC=9 V, f=1 kHz, Ta=25): (1)quiescent current, ICCQ: 4 mA typ and 6 mA max at VIN=0; (2)output current, IO: 15 mA min, 20 mA typ and 30 mA max; (3)output leak current, IO(OFF): 50A max at VIN=0 ; (4)voltage gain, GV: 12.6 dB typ.
