AN6550
Dual Operational Amplifier
■ Overview
The AN6550 is a dual operational amplifier with a phase
compensation circuit built-in, allowing lo w voltage operation.
It is suitable for application to various electronic circuits
such as active filters and audio preamplifiers.
■ Features
• Phase compensation circuit
• High voltage gain, low noise
• Output short protection circuit
• Low voltage operation(±2.5V to±10V)
