AN6555, AN6556, AN6556S
Low Noise Dual Operational Amplifiers
■ Overview
The AN6555, the AN6556, and the AN6556S are low
noise, high slew rate dual operational amplifiers with
phase compensation circuits built-in.
They are suitable for applications to various electronic
circuits such as active filters and audio preamplifiers.
■ Features
• Phase compensation circuit
• High voltage gain:Gv=100 dB typ.
• Low noise:input referred noise voltage Vni=1.5µVrms
typ.
• High slew rate:SR=2V/µs typ.
• Output short-circuit protection
