AN6561, AN6561L
Dual Operational Amplifiers
s Overview
The AN6561 and AN6561L are dual operational amplifiers with two phase compensation circuits built in, have a wide range of operating supply voltage, and can operate on a single power supply. They have electrical characteristics equivalent to those of conventional operational amplifiers, and are lowpowered and suitable for application to various circuits.
