TA7666P datasheet



Both of the TA7666P and the TA7667P consist of two inverting amplifiers, ten comparators and a reference voltage network.  It is suitable for stereo radio cassette applications becasue of dual type.


1. Suitable for Stereo LED Drvier

2. Wide Supply Voltage Range : Vcc = 6 ~ 12 V

3. Low Quiscent Current

4. Variable Voltage Gain Because of Inverting Amplifier

5. Easy Arragement for Dual 10 LED Driver

Block Diagram
