4558D JRC – Dual Operational Amplifier ( Datasheet PDF )

Part Number: 4558D


Package: DIP 8 Type

Manufacturer: Japan Radio Corporation


4558D JRC



This is wide supply voltage range, high input impedance, low input offset voltage, low noise, and high gain.

The NJM4558, 4558D, NJM4559 integrated circuit is a dual high-gain operational amplifier internally compensated and constructed on a single silicon chip using an advanced epitaxial process.

Combining the features of the NJM741 with the close parameter matching and tracking of a dual device on a monolithic chip results in unique performance characteristics.Excellent channel separation allow the use of the dual device in single NJM741 operational amplifier applications providing density.

It is especially well suited for applications in differential-in,defferential-out as well as in potentiometric amplifiers and where gain and phase matched channels are mandatory.

Q: What is the pin configuration of the 4558D?

A: The 4558D has 8 pins. Pin 1 is the output of amplifier 1, pin 2 is the inverting input of amplifier 1, pin 3 is the non-inverting input of amplifier 1, pin 4 is the negative power supply (-Vcc), pin 5 is the non-inverting input of amplifier 2, pin 6 is the inverting input of amplifier 2, pin 7 is the output of amplifier 2, and pin 8 is the positive power supply (+Vcc).


1. Operating Voltage ( ±4V~±18V )

2. High Voltage Gain ( 100dB typ. )

3. High Input Resistance ( 5MΩ typ. )

4. Bipolar Technology




[ Note ]

One common issue with the 4558D is that it is often counterfeited, so it is important to purchase from reputable suppliers.
