What are the key features of RC4559DE4?
- Dual op-amp configuration with 2 independent amplifiers in a single 8-pin SOIC package, halving board space compared to two single op-amp ICs
- 100 dB typical common-mode rejection ratio (CMRR) with 80 dB minimum, providing strong noise rejection for differential signal amplification
- Internal frequency compensation eliminating the need for external compensation capacitors and simplifying PCB layout in audio and signal processing designs
- 0.25 µA typical input bias current at 25°C enabling use with moderately high-impedance signal sources without significant input loading effects
What is RC4559DE4 used for?
The RC4559DE4 is used in general-purpose analog signal processing applications including audio preamplifiers, active filters, and instrumentation front-ends where dual-supply operation and moderate input offset voltage of 7.5 mV are acceptable. Its dual amplifier configuration in SOIC-8 is well suited for differential-to-single-ended conversion, summing amplifiers, and integrators in industrial sensor interfaces operating from ±5 V to ±15 V supply rails. The device also finds use in audio mixing boards and telecommunications signal conditioning circuits where 100 dB CMRR provides adequate noise rejection without requiring premium precision components.

Frequently Asked Questions
What is the CMRR specification of RC4559DE4, and how does it compare in differential amplifier circuits?
The RC4559DE4 achieves a typical CMRR of 100 dB with a guaranteed minimum of 80 dB. In a differential amplifier with a gain of 10 dB, a 100 dB CMRR means common-mode interference such as 50 Hz or 60 Hz power-line noise is attenuated by 90 dB relative to the differential signal, making it suitable for balanced audio and sensor bridge amplifier circuits where mains interference rejection is important.
Does RC4559DE4 require external frequency compensation capacitors?
No, the RC4559DE4 includes internal frequency compensation, so no external capacitors are needed to ensure stability. This simplifies PCB layout by eliminating 2 external compensation capacitors per amplifier channel that older uncompensated op-amps such as LM301 require, reducing BOM cost and saving approximately 4 to 6 component placements in a dual-channel design.
What is the input bias current of RC4559DE4, and is it suitable for high-impedance sensor interfaces?
The RC4559DE4 has a typical input bias current of 0.25 µA and a maximum of 0.5 µA at 25°C. For a source impedance of 100 kΩ, this produces up to 50 mV of input-referred offset error, limiting accuracy for very high-impedance sources. It is better suited for source impedances below 10 kΩ where the resulting 5 mV offset error stays within the 7.5 mV offset voltage specification of the amplifier.
How does placing 2 op-amps in RC4559DE4's SOIC-8 package benefit PCB density in audio designs?
The RC4559DE4 SOIC-8 package occupies approximately 19 mm² of board area and provides 2 fully independent op-amp channels. Using a single RC4559DE4 instead of 2 single-channel op-amps in SOT-23-5 packages saves roughly 5 mm² of area and 1 decoupling capacitor, while also reducing trace routing complexity in stereo audio preamp and active crossover designs where both channels must be placed symmetrically.
