AN6557, AN6558, AN6558S
Dual Low Noise, High Sle w Rate Operational Amplif iers
■ Overview
The AN6557, the AN6558, and the AN6558S are low
noise, high slew rate dual operational amplifiers with
phase compensation circuits built-in. They are suitable
for application to various electronic circuits such as active filters and audio preamplifiers. Moreover, they are
high output current type and can also be used as headphone amplifiers.
■ Features
• Phase compensation circuit
• High voltage gain:GV=100dB typ.
• Low noise:Vni=0.9µVrms typ.
• High slew rate:SR=6V/µs typ.
• High output current:IO=25mA typ.
