■ DESCRIPTION

The AA4556 integrated circuit is a high-gain, high output current dual operational amplifier

capable of driving ±70mA into 150

loads (10.5V output voltage), and operating low supply

voltage(V+/V- = ±2V~).The AA4556 has the capability of driving 150

loads. In addition, the

wide band-width, low noise, high slew rate and low distortion of the AA4556 make it ideal for

many audio, telecommunications and instrumentation applications.
