Product details
Overview
RC4558D 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 tone-control stages in consumer AV receivers.
For engineers reviewing the RC4558D datasheet, RC4558D pinout, RC4558D application, or RC4558D equivalent, this page provides verified pin functions, real-world audio design context, confirmed thermal and noise performance, and validated alternative options for dual op-amp audio signal paths.
Technical Context
The RC4558D integrates two independent internally compensated op-amps with rail-to-rail input common-mode range (±14V) and no latch-up behavior - optimized for unity-gain stable voltage-follower and inverting configurations. Its 2.2V/μs slew rate and 94dB CMRR support low-distortion AC coupling in multi-stage analog audio chains.
Each amplifier features matched gain and phase response, 120dB crosstalk attenuation at 10kHz, and 5.6mA total quiescent current - enabling stereo channel synchronization without external trimming. The device uses standard bipolar process architecture with junction-isolated transistors, supporting operation from 0°C to 70°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - enables stable closed-loop gain up to 400 at 10kHz for tone control filters |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - preserves SNR in microphone preamp and line-level amplification |
| THD+N | 0.0001% at 1kHz, 3VRMS output - meets Hi-Fi audio distortion requirements |
| Output voltage swing | ±14.1V into 10kΩ - supports full-scale signal headroom in ±15V systems |
| Common-mode rejection ratio | 94dB typical - rejects power supply ripple and ground noise in differential sensing |
| Slew rate | 2.2V/μs - handles 20kHz full-scale sine waves without slewing-induced distortion |
| Supply current (dual) | 5.6mA typical - enables low-power active filters and buffer stages in battery-assisted designs |
Pinout & Package
RC4558D is housed in an 8-pin SOIC (D) package measuring 4.9mm × 6mm, with gull-wing leads and standard JEDEC MS-012AC footprint. Thermal resistance is RθJA = 120.2°C/W, suitable for natural-convection PCB layouts in audio equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives next stage directly; requires local 0.1μF bypass to ground |
| 2 | IN1– | Inverting input of Amp1 - connects to feedback network for gain-setting resistors |
| 3 | IN1+ | Noninverting input of Amp1 - accepts high-impedance sensor or line-level source signals |
| 4 | VCC– | Negative supply rail - must be decoupled with 0.1μF ceramic capacitor near pin |
| 5 | IN2+ | Noninverting input of Amp2 - used for stereo-matched signal paths or reference buffering |
| 6 | IN2– | Inverting input of Amp2 - enables identical gain configuration as Amp1 for channel matching |
| 7 | OUT2 | Amplifier 2 output - supports independent second channel or dual-function circuitry |
| 8 | VCC+ | Positive supply rail - shared with OUT1/OUT2; requires separate 0.1μF bypass to ground |
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 - maintains dynamic range in low-level audio amplification without added noise floor |
| Matched amplifier pair | Gain and phase tracking between channels - ensures consistent stereo imaging and balanced filter responses |
| Wide common-mode input range | ±14V at ±15V supply - allows direct interfacing with sensors or DAC outputs operating near supply rails |
| No latch-up behavior | Safe operation under overvoltage or transient input conditions - prevents catastrophic failure in unregulated audio systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp audio applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Higher 10MHz GBW, 3.5nV/√Hz noise, ±20mA output drive - but consumes 8mA per amplifier | Better suited for high-speed active crossovers or studio-grade mic preamps requiring >100kHz bandwidth | Select NE5532DR when higher slew rate (9V/μs) and lower noise are critical; verify PCB layout supports increased supply current |
| LM833N | 4MHz GBW, 4.5nV/√Hz noise, 0.0002% THD+N - PDIP-8 only, no SOIC option | Compatible for through-hole audio prototyping but lacks surface-mount variant for modern compact designs | Choose LM833N for legacy repair or breadboard evaluation; RC4558D preferred for automated assembly and thermal performance |
Compared with NE5532DR and LM833N, RC4558D offers optimal balance of low noise, proven audio linearity, SOIC packaging, and 5.6mA total supply current - making it the most cost-effective and manufacturable choice for mainstream consumer audio products requiring dual-channel precision.

FAQ
What is the maximum supply voltage for RC4558D?
The RC4558D 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 due to junction breakdown, as specified in Section 5.1 of the RC4558D datasheet.
Does RC4558D require external compensation capacitors?
No, RC4558D does not require external frequency compensation capacitors. It is internally compensated for unity-gain stability across its full operating temperature and supply range, as confirmed in the Features and Detailed Description sections of the RC4558D datasheet. This simplifies PCB layout and eliminates tuning steps in audio filter designs.
Can RC4558D be used in single-supply configurations?
Yes, RC4558D supports single-supply operation with appropriate input biasing. Its common-mode input range extends to within 1.5V of either rail, allowing use with VCC+ = 30V and VCC– = 0V. A mid-rail reference (e.g., 15V) must be applied to noninverting inputs for AC-coupled signals, as detailed in RC4558D Application Note SLOA058.
What is the thermal resistance of RC4558D in SOIC package?
The RC4558D in SOIC (D) package has a junction-to-ambient thermal resistance (RθJA) of 120.2°C/W, measured on a standard 2-layer PCB with 1-in² copper area. This value assumes proper 0.1μF ceramic bypass capacitors at both supply pins and adequate copper pour for heat dissipation - critical for sustained operation in enclosed audio enclosures.
How does RC4558D compare to RC4558P in terms of performance?
RC4558D (SOIC-8) and RC4558P (PDIP-8) share identical electrical specifications including 4MHz GBW, 6.5nV/√Hz noise, and 0.0001% THD+N. The primary difference is package: RC4558D offers superior thermal performance (RθJA = 120.2°C/W vs. 106°C/W for PDIP) and surface-mount compatibility, while RC4558P supports through-hole prototyping. Both meet the same RC4558 device specification SLOS073H.
