JRC4558 Dual Op-Amp
The JRC4558 is a high performance monolithic dual operational amplifier. JRC4558 internally compensated and constructed on a single silicon chip. The high voltage gain (100 dB typ.), good input impedance (5 MΩ typ.) and versatile power supply (± 4 to 18 Volts) make it perfect to fit in pedal circuit designs.
