Product details
Overview
RC4558IDR 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, ±14.1V output swing (RL = 10kΩ), and operates across ±5V to ±15V supply rails. It serves as a low-noise, low-distortion gain stage in AV receivers and professional audio mixers.
For engineers reviewing the RC4558IDR datasheet, RC4558IDR pinout, RC4558IDR application, or RC4558IDR equivalent, this page provides verified specifications, SOIC-8 package mapping, dual-amplifier functional context, and validated alternatives for audio-grade op-amp selection and layout-sensitive analog design.
Technical Context
The RC4558IDR integrates two independent high-fidelity op-amps on a single die with internal frequency compensation-enabling stable unity-gain operation without external components. Its wide common-mode input range (±14V) and latch-up immunity support robust voltage-follower and active filter configurations in dual-supply audio paths.
Each amplifier features matched gain and phase response, 94dB CMRR, 2.2V/μs slew rate, and 120dB crosstalk attenuation at 10kHz-ensuring channel integrity in stereo preamplification and differential driver stages where inter-channel interference must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - supports stable closed-loop gain up to 400× at 10kHz or unity gain up to 4MHz without external compensation. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - enables low-noise amplification of line-level audio signals without audible hiss in 20Hz–20kHz band. |
| THD+N | 0.0001% at 1kHz, 3VRMS, RL = 2kΩ - preserves harmonic fidelity in high-fidelity audio signal chains with negligible added distortion. |
| Output voltage swing | ±14.1V into 10kΩ - delivers full-scale dynamic range for ±15V-rail systems with ≥0.9V headroom, minimizing clipping in analog mixing stages. |
| Common-mode rejection ratio | 94dB typical - rejects power-supply ripple and ground-bounce coupling in shared-bias audio circuits. |
| Supply current (both amps) | 5.6mA typical at 25°C - enables thermally efficient dual-channel amplification in space-constrained audio PCBs. |
| Slew rate | 2.2V/μs - handles transient-rich audio waveforms (e.g., drum transients) with <1% distortion up to ~350kHz. |
Pinout & Package
RC4558IDR is supplied in an 8-pin SOIC (D) package measuring 4.9mm × 6mm, optimized for automated assembly and thermal dissipation in audio PCBs (RθJA = 120.2°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 output | Low-impedance buffered output node; drives loads ≥2kΩ with minimal phase shift up to 100kHz. |
| 2 | Amplifier 1 inverting input | Inverts and sums feedback signals; requires matched trace routing to minimize imbalance-induced distortion. |
| 3 | Amplifier 1 noninverting input | High-impedance input (550MΩ || 5.6pF); sensitive to EMI-must be shielded and kept short in PCB layout. |
| 4 | Negative supply (VCC−) | Reference return for both amplifiers; must connect to clean, low-impedance ground plane with local 0.1μF ceramic bypass. |
| 5 | Amplifier 2 noninverting input | Independent high-Z input for second channel; shares same bias current spec (80nA typ) as Pin 3 for matched DC performance. |
| 6 | Amplifier 2 inverting input | Second inverting node; identical electrical behavior to Pin 2-supports stereo-matched gain-setting resistor networks. |
| 7 | Amplifier 2 output | Electrically isolated output path; 120dB crosstalk attenuation ensures <0.0001% inter-channel leakage at 10kHz. |
| 8 | Positive supply (VCC+) | Power rail for both amplifiers; requires dedicated 0.1μF ceramic capacitor placed ≤2mm from Pin 8 to suppress supply-induced noise. |
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. |
| Matched gain and phase between amplifiers | Enables true stereo signal processing with ≤0.1dB gain error and ≤0.5° phase mismatch across 20Hz–20kHz. |
| Wide common-mode input voltage range | ±14V at ±15V supplies-supports rail-to-rail input buffering without level-shifting in dual-supply audio front-ends. |
| No latch-up under overvoltage conditions | Withstands input transients beyond supply rails (±30V differential) without destructive latch-up-improves system reliability. |
| Low distortion and noise | 0.0001% THD+N + 6.5nV/√Hz noise floor-meets Class A audio preamp requirements for studio-grade signal integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual general-purpose operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Higher slew rate (9V/μs), lower input noise (5nV/√Hz), but higher quiescent current (8mA vs 5.6mA). | Better suited for high-speed active crossovers and headphone drivers; less optimal for low-power soundbars. | Select NE5532DR when >5MHz small-signal bandwidth or <5nV/√Hz noise is required; verify thermal margin due to higher ICC. |
| TL072CDR | Lower input bias current (30pA vs 80nA), JFET-input architecture, but higher THD+N (0.003% vs 0.0001%) and lower output swing (±12V). | Preferred for high-impedance sensor interfaces; unsuitable for low-distortion line-level audio where THD+N < 0.001% is mandatory. | Choose TL072CDR only for DC-coupled high-Z source buffering; avoid in critical audio gain stages where harmonic purity is specified. |
Compared with NE5532DR and TL072CDR, RC4558IDR offers the best balance of ultra-low THD+N, adequate bandwidth, and moderate power consumption for cost-sensitive consumer audio-making it ideal for AV receivers and wireless speakers where fidelity and efficiency coexist.

FAQ
What is the maximum supply voltage for RC4558IDR?
The RC4558IDR has absolute maximum supply ratings of ±18V, but its recommended operating range is ±5V to ±15V. Operating at ±15V enables the full ±14.1V output swing into 10kΩ loads. Exceeding ±18V risks permanent damage per the Absolute Maximum Ratings table in the RC4558IDR datasheet.
Does RC4558IDR require external compensation capacitors?
No, RC4558IDR does not require external compensation capacitors. It features internal frequency compensation optimized for unity-gain stability across its full operating range. This eliminates layout sensitivity and component count in standard inverting and noninverting configurations, as confirmed in Section 6.3.1 and Figure 5-2 of the RC4558IDR datasheet.
What is the input offset voltage specification for RC4558IDR?
The RC4558IDR has a typical input offset voltage of 0.3mV and a maximum of 6mV at 25°C (full-range max is 7.5mV). This low VOS ensures minimal DC error in precision gain stages and active filters, supporting accurate DC-coupled audio paths without blocking capacitors in the RC4558IDR signal chain.
How does RC4558IDR perform in terms of channel crosstalk?
The RC4558IDR achieves 120dB crosstalk attenuation at 10kHz (RS = 1kΩ), meaning less than 0.0001% of signal leaks from one amplifier to the other. This performance is critical in stereo applications like professional audio mixers, where channel separation directly impacts imaging accuracy and is explicitly characterized in the RC4558IDR Electrical Characteristics table.
Is RC4558IDR suitable for single-supply operation?
Yes, RC4558IDR supports single-supply operation with appropriate input/output biasing. While optimized for ±5V to ±15V dual supplies, it can function with a single 10V–30V rail using a mid-rail virtual ground. The wide common-mode input range (±14V) and absence of latch-up allow reliable operation in such configurations, as detailed in Section 6.4 of the RC4558IDR datasheet.
