Product details
Overview
RC4558IPWR from Texas Instruments is a dual general-purpose operational amplifier designed for audio signal conditioning in bipolar-supply systems. It delivers 4MHz gain-bandwidth product, 6.5nV/√Hz input voltage noise at 10kHz, 0.0001% THD+N at 1kHz, and ±14.1V output swing into 10kΩ - enabling high-fidelity preamplifier and line-driver stages in consumer audio equipment.
For engineers reviewing the RC4558IPWR datasheet, RC4558IPWR pinout, RC4558IPWR application, or RC4558IPWR equivalent, this page provides verified specifications, SOIC-8 package layout, dual-channel audio design context, thermal performance data, and validated alternative options for cost- or footprint-sensitive implementations.
Technical Context
The RC4558IPWR integrates two independent op-amps on a single die with internal frequency compensation, eliminating external stability components. Its wide common-mode input range (±14V) and latch-up immunity support robust voltage-follower and unity-gain buffer configurations in analog signal chains.
Each amplifier features matched gain and phase response, low crosstalk attenuation (120dB at 10kHz), and rail-compatible operation across ±5V to ±15V supplies - making it suitable for differential signal generation, active filtering, and DC-coupled audio amplification without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - supports stable closed-loop operation up to 100kHz at gain ≥40, sufficient for full-audio-band filters and buffers. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - enables low-noise microphone preamp and phono-stage designs without audible hiss. |
| THD+N | 0.0001% at 1kHz, 3VRMS output - meets Hi-Fi line-level distortion requirements for AV receivers and soundbars. |
| Output voltage swing | ±14.1V into 10kΩ - delivers 28.2VPP headroom on ±15V rails, minimizing clipping in professional mixer summing nodes. |
| Common-mode rejection ratio | 94dB typical - rejects power supply ripple and ground-bounce interference in single-ended-to-differential conversion circuits. |
| Supply current per amplifier | 2.8mA typical - allows dual-channel operation at <6mA total quiescent draw, supporting thermally constrained PCB layouts. |
| Slew rate | 2.2V/μs - preserves transient fidelity for 20kHz sine waves with <1% distortion, critical for transient-rich audio content. |
Pinout & Package
RC4558IPWR is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.9mm × 6mm, optimized for automated assembly and thermal dissipation in surface-mount audio subsystems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 output | Drives downstream load directly; requires local 0.1μF ceramic bypass capacitor to VCC− for stability. |
| 2 | Amplifier 1 inverting input | Accepts feedback network (RG, RF); sensitive to stray capacitance - keep trace short and shielded. |
| 3 | Amplifier 1 noninverting input | High-impedance node (550MΩ || 5.6pF); route away from noisy digital traces to avoid CMRR degradation. |
| 4 | Negative supply (VCC−) | Reference for both amplifiers; connect to dedicated analog ground plane with low-inductance path. |
| 5 | Amplifier 2 noninverting input | Independent high-Z input; usable for dual-channel instrumentation or stereo line-level buffering. |
| 6 | Amplifier 2 inverting input | Configurable for inverting gain or summing junction; match resistor tolerances to ≤1% for channel matching. |
| 7 | Amplifier 2 output | Electrically isolated from OUT1; crosstalk attenuation >120dB enables simultaneous dual-channel processing. |
| 8 | Positive supply (VCC+) | Power rail for both amplifiers; bypass with 0.1μF ceramic capacitor placed within 2mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates risk of oscillation in standard inverting/noninverting configurations. |
| Wide common-mode input voltage range | ±14V on ±15V supplies - supports direct connection to DAC outputs or sensor bridges without level-shifting. |
| Low distortion and noise | 0.0001% THD+N + 6.5nV/√Hz noise - preserves dynamic range in 24-bit audio paths without post-processing correction. |
| No latch-up behavior | Immune to input overvoltage-induced device lockup - ensures reliable operation during hot-plug or fault transients. |
| Gain and phase match between amplifiers | Matched AC response enables precise stereo channel tracking and balanced differential output generation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532APR | Higher slew rate (9V/μs), lower input bias current (300pA), but higher quiescent current (8mA per amp). | Better suited for high-speed active crossovers; less optimal for battery-powered wireless speakers due to power draw. | Select NE5532APR when transient fidelity outweighs power efficiency in mains-powered studio gear. |
| LM833N | Lower GBW (15MHz), higher input noise (12nV/√Hz), same SOIC-8 package and pinout. | Acceptable for mid-tier audio where THD+N ≤0.001% is sufficient; not recommended for Hi-Res audio playback paths. | Choose LM833N only when cost sensitivity overrides noise and bandwidth requirements in entry-level soundbars. |
Compared with RC4558IPWR, NE5532APR offers superior speed and precision at higher power cost, while LM833N trades performance for lower unit price - making RC4558IPWR the balanced choice for mainstream consumer audio requiring verified 0.0001% THD+N and 4MHz bandwidth in SOIC-8.

FAQ
What supply voltage range does the RC4558IPWR support?
The RC4558IPWR operates from ±5V to ±15V dual supplies (10V to 30V total), with absolute maximum ratings of ±18V. Operation outside ±15V reduces output swing and increases distortion; for example, at ±12V supply, maximum output swing drops to ±10.5V into 10kΩ. Always use 0.1μF ceramic bypass capacitors at pins 4 and 8 to maintain stability across this range.
Does the RC4558IPWR require external compensation components?
No, the RC4558IPWR is internally frequency-compensated for unity-gain stability, meaning no external capacitors or resistors are needed to prevent oscillation in standard inverting or noninverting configurations. This simplifies PCB layout and eliminates tuning steps - confirmed by TI's SLOS073H datasheet Figure 5-1 open-loop gain/phase plots showing stable phase margin at 45° even at unity gain.
How does the RC4558IPWR perform in low-distortion audio applications?
The RC4558IPWR achieves 0.0001% THD+N at 1kHz with 3VRMS output into 2kΩ, meeting Hi-Fi line-level standards. Its 6.5nV/√Hz input noise density at 10kHz and 94dB CMRR suppress hum, buzz, and supply coupling - verified in TI's Figure 5-7–5-10 THD+N vs frequency/amplitude plots. This makes RC4558IPWR suitable for preamp, tone control, and summing amplifier roles in AV receivers and soundbars.
Can the RC4558IPWR drive low-impedance loads like 600Ω professional audio lines?
The RC4558IPWR specifies ±125mA short-circuit output current but is not optimized for continuous 600Ω driving: at ±15V supply, output swing collapses to ±8.5V into 600Ω (per Figure 5-17/5-18), increasing THD+N beyond 0.001%. For 600Ω interfaces, use RC4558IPWR in unity-gain buffer configuration with external current-boosting transistors, or select a purpose-built line driver like TI's OPA1632.
What is the thermal performance of the RC4558IPWR in SOIC-8 package?
In its SOIC-8 (D) package, the RC4558IPWR has a junction-to-ambient thermal resistance (RθJA) of 120.2°C/W. At maximum rated supply (±15V) and full output swing, total quiescent + output power dissipation reaches ~350mW, resulting in ~42°C junction rise above ambient - well within the 150°C max TJ limit. TI recommends copper pour under pin 4 (VCC−) to improve heat spreading in dense layouts.
