Dual Operational Amplifier. The 4558 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 allows the use of the dual device in single NJM741 operational amplifier applications providing density. It is especially well suited for applications in differential-in, differential-out as well as in potentiometric amplifiers and where gain and phase matched channels are mandatory.
Features:

• Operating Voltage ( ±4V~±18V )
• High Voltage Gain ( 100dB typ. )
• High Input Resistance ( 5MΩ typ. )
• Bipolar Technology

A semiconductor device which passes current in the forward direction(from anode to cathode), and blocks current in the opposite direction.

This a high performance dual low noise operational amplifier. Compared to the standard dual operational amplifiers, such as the NJM1458, it shows better noise performance, improved output drive capability, and considerably higher small-signal and power bandwidths. it is compensated internally for voltage follower circuit. This makes the device especially suitable for application in high quality and professional audio equipment, instrumentation, control circuits, and telephone channel amplifiers
Features:

• Operating Voltage = ±3V~±22V
• Small Signal Bandwidth = 10MHz typ.
• Output Drive Capability = 600Ω,10Vrms typ.
• Input Noise Voltage = 5nV/√Hz typ.
• Power Bandwidth = 140kHz typ.
• Slew Rate = 8V/µs typ.
• Bipolar Technology

A full wave rectifier with 4 elements in a bridge circuit so that DC voltage is obtained from one pair of junctions when an AC voltage is applied to another pair of junctions.
