![]() ![]() As mentioned above JRC4558 is a dual operational amplifiers IC but in this circuit we have used only one internal opamp. The figure shows an application circuit of JRC4558 IC, this is a preamplifier circuit built around this IC. ![]() Replacement and Equivalent / Other Part Numbers The minimum and maximum supply current required by the IC for both operational amplifiers in no load condition is 2.3mA to 4.5mA. The IC has industry standard pin compatibility due to which it can easily be replaced with many substitute dual op amp ICs. The IC also has a high voltage gain of up to 100dB. The IC has many features which makes it ideal to use in commercial equipment and devices like low cost and high reliability, high voltage gain, low current consumption, etc. Moreover, this IC is also used by electronic students, hobbyists, and tinkerers in their audio projects. JRC is a very famous IC among guitar pedal makers and provides very high performance in these types of circuits. The IC contains two separate op amp inside which can be operated from a single or dual power supply. JRC4558 is a dual opamp IC available in an 8 pin dip and SOP-8 package. Positive Supply for both Op-amps of the IC Non Inverting Input of IC's Second Op-amp Ground / Negative For Both Op-amps of the IC. Suitable for portable / battery operated devices.įirst Operational Amplifier Output of IC.Reliable to use in commercial equipment & devices.All input transistors are low noise types.Can be operated from +15 and -15V (When operated with dual supply).Can be operated from +5V to +15V (When operated with a single supply).Single and dual power supply operations.Two separate operational amplifiers in a single package.Advertisements JRC4558 IC Features / Technical Specifications
