Product details
Overview
RC4558PSRG4 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 from ±5V to ±15V supplies. It is used in AV receivers and professional audio mixers where low distortion and wide common-mode range are critical.
For engineers reviewing the RC4558PSRG4 datasheet, RC4558PSRG4 pinout, RC4558PSRG4 application, or RC4558PSRG4 equivalent, this page provides verified specifications, SOP-8 package details, dual-amplifier functional context, thermal performance data, and validated alternative options for audio-grade op-amp selection.
Technical Context
The RC4558PSRG4 integrates two independent high-fidelity op-amps on a single die with internal frequency compensation, eliminating external stability components. Its ±14V common-mode input range and latch-up immunity support robust voltage-follower and unity-gain buffer configurations in analog front-ends.
Each amplifier features matched gain and phase response, 94dB CMRR, 2.2V/μs slew rate, and 120dB crosstalk attenuation at 10kHz - enabling precise dual-channel signal processing without inter-channel interference in stereo or differential-output circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - supports stable closed-loop operation up to 4MHz at unity gain, suitable for audio bandwidth and medium-speed signal conditioning. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - enables low-noise preamplification in line-level audio paths without audible hiss. |
| THD+N | 0.0001% at 1kHz, 3VRMS output - ensures transparent signal reproduction in high-fidelity audio applications. |
| Output voltage swing | ±14.1V into 10kΩ load - delivers full dynamic range across ±15V supplies with minimal clipping in line-driver stages. |
| Common-mode input range | ±14V - allows direct interfacing with signals near supply rails, e.g., in DC-coupled active filters or level-shifting buffers. |
| Slew rate | 2.2V/μs - preserves transient fidelity for audio transients up to ~350kHz without slew-induced distortion. |
| Supply current (dual) | 5.6mA typical - balances low power consumption with high AC performance for thermally constrained PCB layouts. |
Pinout & Package
RC4558PSRG4 is packaged in an 8-pin SOP (Small Outline Package) with 6.2mm × 7.8mm footprint and standard 1.27mm pitch. The package is surface-mount, RoHS-compliant, and rated for 0°C to 70°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 output | Low-impedance buffered output node; drives loads ≥2kΩ with <1% THD+N at 1kHz. |
| 2 | Amplifier 1 inverting input | Differential input terminal; accepts feedback networks for inverting gain configurations. |
| 3 | Amplifier 1 noninverting input | High-impedance input node; used for unity-gain buffers and noninverting amplifiers. |
| 4 | Negative supply (VCC–) | Reference return for dual-supply operation; must be decoupled with 0.1μF ceramic capacitor. |
| 5 | Amplifier 2 noninverting input | Independent high-Z input for second channel; electrically isolated from Channel 1 inputs. |
| 6 | Amplifier 2 inverting input | Second differential input; supports matched gain-setting resistors for stereo gain matching. |
| 7 | Amplifier 2 output | Second low-Z output; exhibits ≤0.5dB gain/phase mismatch vs. Pin 1 over 20Hz–20kHz. |
| 8 | Positive supply (VCC+) | Power rail for dual-supply operation; requires local 0.1μF bypass to ground for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates risk of oscillation in basic buffer or gain-of-1 configurations. |
| Low input voltage noise | 6.5nV/√Hz at 10kHz - maintains SNR >105dB in 20kHz audio bandwidth with 10kΩ source impedance. |
| Matched amplifier pair | Gain and phase tracking within 0.5dB/1° over 20Hz–100kHz - enables accurate stereo channel balancing and differential signaling. |
| Wide common-mode input range | ±14V at ±15V supplies - supports DC-coupled inputs without level-shifting circuitry in line-level interfaces. |
| No latch-up behavior | Immune to input overvoltage-induced latch-up - enhances reliability in systems with hot-plug or transient-prone signal sources. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual general-purpose op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Higher slew rate (9V/μs), lower input bias current (300nA typ), but higher quiescent current (8mA per amp). | Better suited for high-slew audio drivers; less optimal for low-power battery-operated wireless speakers. | Choose NE5532DR when driving low-impedance loads (<600Ω) or requiring faster transient response than RC4558PSRG4's 2.2V/μs. |
| LM833N | Identical pinout and gain-bandwidth (4MHz), but higher input noise (10nV/√Hz) and higher THD+N (0.002% at 1kHz). | Acceptable for cost-sensitive consumer audio where 0.0001% THD+N is not mandatory. | Choose LM833N only if budget constraints outweigh fidelity requirements and noise performance is secondary. |
Compared with RC4558PSRG4, NE5532DR offers superior drive strength and speed at higher power cost, while LM833N trades measurable audio fidelity for lower unit cost - making RC4558PSRG4 the balanced choice for mid-tier audio equipment requiring verified 0.0001% THD+N and 6.5nV/√Hz noise.

FAQ
What is the maximum supply voltage for RC4558PSRG4?
The absolute maximum supply voltage for RC4558PSRG4 is ±18V, but the recommended operating range is ±5V to ±15V. Operation beyond ±15V risks exceeding thermal limits and degrading long-term reliability. At ±15V, RC4558PSRG4 delivers ±14.1V output swing into 10kΩ, confirming safe margin within its specified range.
Does RC4558PSRG4 require external compensation capacitors?
No, RC4558PSRG4 is internally frequency-compensated for unity-gain stability. External compensation is unnecessary in standard inverting, noninverting, or voltage-follower configurations. This simplifies layout and eliminates tuning steps - a key advantage confirmed in TI's SLOS073H datasheet Section 6.3.1.
What is the input offset voltage specification for RC4558PSRG4?
The typical input offset voltage for RC4558PSRG4 is 6mV, with a maximum of 7.5mV over the full 0°C to 70°C operating range. At room temperature (25°C), the value is tighter - 0.3mV minimum and 6mV typical - enabling accurate DC-coupled applications like active filters and sensor signal conditioning.
Can RC4558PSRG4 be used in single-supply configurations?
Yes, RC4558PSRG4 supports single-supply operation by biasing inputs and outputs around a mid-rail reference (e.g., VCC/2). Its wide common-mode input range (±14V at ±15V) and rail-swing capability allow functional use down to 10V total supply (e.g., 0V to +10V), though dual-supply operation yields optimal THD+N and noise performance.
What thermal metrics apply to RC4558PSRG4 in SOP-8 package?
In its PS (SOP-8) package, RC4558PSRG4 has a junction-to-ambient thermal resistance (RθJA) of 122.9°C/W and junction-to-board (RθJB) of 77.5°C/W. These values assume standard JEDEC 2-layer board conditions; actual thermal performance improves with copper pour and thermal vias - critical for sustained 5.6mA supply current in enclosed audio enclosures.
