What are the key features of RC4558DG4?

  • Dual op-amp in a single 8-pin SOIC package reduces component count and PCB area in stereo audio and differential signal conditioning designs
  • 90 dB typical common-mode rejection ratio with internal frequency compensation minimizes external component requirements for stable closed-loop operation
  • Wide supply range of ±5 V to ±15 V allows use across battery-powered portable systems and ±15 V benchtop instrumentation without circuit redesign

What is RC4558DG4 used for?

RC4558DG4 suits audio preamplifier stages, active filter networks, and instrumentation signal conditioning circuits where two op-amps are needed in a compact 8-pin footprint. Its 90 dB CMRR and bipolar supply operation make it a dependable choice for consumer audio equipment, function generators, and test instrument front-ends. The device is widely used in legacy industrial designs and repair applications thanks to its industry-standard pinout and broad availability.

Frequently Asked Questions

What supply voltage range does RC4558DG4 support, and how does that affect circuit design flexibility?

RC4558DG4 operates from ±5 V to ±15 V dual supply, covering the full range from 5 V bench instruments to battery-powered equipment using ±5 V rails. This broad range allows the same device to be reused across multiple product variants without redesigning the analog signal chain or changing component values significantly.

How does the 90 dB CMRR of RC4558DG4 benefit audio and instrumentation applications?

A 90 dB typical CMRR means RC4558DG4 attenuates common-mode noise such as 50 Hz or 60 Hz mains pickup by a factor of approximately 31,000:1 relative to the differential signal. In audio preamplifiers and sensor interfaces with long cable runs, this level of rejection preserves signal fidelity and reduces the need for additional shielding or filtering.

Is RC4558DG4 a pin-compatible replacement for the industry-standard LM358 or TL072 in existing PCB designs?

RC4558DG4 shares the same 8-pin dual op-amp pinout as the industry-standard RC4558 family and is layout-compatible with many dual op-amp footprints. However, it requires a dual ±5 V to ±15 V supply, unlike single-supply parts such as LM358. For designs already using bipolar supplies, RC4558DG4 is a direct functional substitute with equivalent 7.5 mV maximum input offset and 0.5 µA bias current specifications.
