Product details
Overview
RC4558ID 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 supplies - enabling high-fidelity preamplifier and line-driver stages in consumer AV receivers.
For engineers reviewing the RC4558ID datasheet, RC4558ID pinout, RC4558ID application, or RC4558ID equivalent, this page provides verified electrical specifications, dual-amplifier pin mapping, thermal derating guidance, and validated audio-system use cases - all aligned with TI's SLOS073H production data sheet (October 2024 revision).
Technical Context
The RC4558ID integrates two independent op-amps on a single die with internal frequency compensation, eliminating external compensation components. Its wide common-mode input range (±14V) and latch-up immunity support stable voltage-follower configurations in analog signal chains.
Each amplifier features matched gain and phase response, 94dB CMRR, 2.2V/μs slew rate, and low crosstalk attenuation (120dB at 10kHz), making it suitable for stereo channel processing where inter-channel integrity is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - enables stable unity-gain operation up to 4MHz without external compensation. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - supports low-noise audio preamplification without audible hiss in line-level circuits. |
| THD+N | 0.0001% at 1kHz, 3VRMS output - ensures minimal harmonic distortion in high-fidelity audio paths. |
| Output voltage swing | ±14.1V into 10kΩ load - delivers full dynamic range when powered from ±15V rails. |
| Common-mode rejection ratio | 94dB typical - rejects power-supply ripple and ground-bounce interference in differential sensing. |
| Supply current (dual) | 5.6mA typical at 25°C - enables moderate-power audio stages without excessive thermal load. |
| Slew rate | 2.2V/μs - preserves transient fidelity for music signals with fast attack transients (e.g., percussion). |
Pinout & Package
RC4558ID is packaged in an 8-pin SOIC (D package), measuring 4.9mm × 6mm, with standard surface-mount footprint and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 output | Drives external load or feedback network; requires local bypass capacitor for stability. |
| 2 | Amplifier 1 inverting input | Accepts feedback signal; sensitive to stray capacitance - keep trace short and shielded. |
| 3 | Amplifier 1 noninverting input | High-impedance signal entry point; route away from noisy supply or output traces. |
| 4 | Negative supply (VCC–) | Reference return for dual-supply operation; connect to dedicated analog ground plane. |
| 5 | Amplifier 2 noninverting input | Independent signal path for second channel; matches AC performance of Pin 3. |
| 6 | Amplifier 2 inverting input | Feedback node for second amplifier; electrically isolated from Pin 2 to prevent crosstalk. |
| 7 | Amplifier 2 output | Second channel output; layout symmetry with Pin 1 minimizes inter-channel timing skew. |
| 8 | Positive supply (VCC+) | Power rail for both amplifiers; decouple with 0.1μF ceramic capacitor placed ≤2mm from pin. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates risk of oscillation in basic inverting/noninverting configurations. |
| Low input voltage noise | 6.5nV/√Hz at 10kHz - preserves signal-to-noise ratio in microphone preamp and phono stage applications. |
| Matched amplifier pair | Gain and phase tracking between channels ensures consistent stereo imaging and balanced output drive. |
| Wide common-mode input range | ±14V at ±15V supply - supports DC-coupled inputs and rail-to-rail signal handling without clipping. |
| No latch-up behavior | Immune to input overvoltage-induced latch-up - enhances reliability in voltage-follower and buffer roles. |
Applications
| AV Receivers | Professional Audio Mixers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp 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 filters and ultralow-noise microphone preamps; less optimal for battery-sensitive designs. | Select NE5532DR when THD+N <0.00005% and bandwidth >10MHz are required; RC4558ID remains preferred for cost-sensitive, thermally constrained audio line stages. |
| LM833N | Identical pinout and supply range, but lower GBW (15MHz), higher THD+N (0.002%), and no guaranteed crosstalk spec. | Acceptable for non-critical stereo line drivers where channel matching is not essential. | Choose LM833N only for legacy-replacement scenarios requiring identical DIP-8 footprint; RC4558ID offers superior noise and distortion specs for new designs. |
Compared with NE5532DR and LM833N, RC4558ID delivers the best balance of low noise, low distortion, and thermal efficiency in dual-supply audio signal chains - particularly where PCB area, BOM cost, and power dissipation are constrained.

FAQ
What is the maximum supply voltage for RC4558ID?
The absolute maximum supply voltage for RC4558ID is ±18V, but the recommended operating range is ±5V to ±15V per TI's SLOS073H datasheet. Operation beyond ±15V risks exceeding thermal limits and degrading long-term reliability; sustained use at ±18V is not advised. The RC4558ID achieves optimal THD+N and output swing within the ±15V range.
Does RC4558ID require external compensation capacitors?
No, RC4558ID does not require external frequency compensation capacitors. It is internally compensated for unity-gain stability across its full operating temperature range (0°C to 70°C), as confirmed in Section 6.3.1 of the SLOS073H datasheet. This simplifies PCB layout and eliminates tuning variability in production.
What is the input offset voltage specification for RC4558ID?
The RC4558ID has a typical input offset voltage of 6mV, with a maximum of 7.5mV over the full operating temperature range (0°C to 70°C). At 25°C, the min/typ/max values are 0.3mV / 6mV / 7.5mV. This specification is measured under open-loop conditions with zero common-mode input voltage, per Section 5.5 of the official datasheet.
Can RC4558ID be used in single-supply configurations?
Yes, RC4558ID can operate from a single supply, provided the input common-mode range and output swing remain within specification. For example, with +30V and GND, the input must stay between +3V and +27V, and output swing is limited to ~+2V to +28V. However, TI specifies performance parameters primarily for dual-supply operation (±5V to ±15V), and RC4558ID is not rail-to-rail - so careful biasing is required in single-supply use.
How does RC4558ID compare to RC4558P in terms of performance?
RC4558ID (SOIC) and RC4558P (PDIP) share identical electrical specifications, including gain-bandwidth product, noise, THD+N, and input/output characteristics - as confirmed in TI's Package Information table and Electrical Characteristics section. The only differences are mechanical: RC4558ID uses a surface-mount SOIC-8 package (4.9mm × 6mm), while RC4558P uses through-hole PDIP-8 (9.81mm × 9.43mm); thermal resistance (RθJA) differs (120.2°C/W vs 106°C/W), affecting power dissipation limits.
