Product details
Overview
RC4558P from Texas Instruments is a dual general-purpose operational amplifier in an 8-pin PDIP package, delivering 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 rail-to-rail common-mode input range up to ±14V - deployed in professional audio mixers and AV receivers for low-distortion signal conditioning.
For engineers reviewing the RC4558P datasheet, RC4558P pinout, RC4558P application, or RC4558P equivalent, key selection criteria include dual-channel matching performance, wide supply range (±5V to ±15V), internal frequency compensation for unity-gain stability, low-noise audio-grade operation, and compatibility with legacy through-hole PCB layouts using the PDIP-8 footprint.
Technical Context
The RC4558P integrates two independent high-fidelity op-amps on a single die with matched gain and phase response, enabling precise differential signal generation and stereo channel processing. Its internal frequency compensation eliminates external compensation components while maintaining stability across 4MHz bandwidth.
It supports dual-supply operation from ±5V to ±15V and features high common-mode rejection (94dB typical) and power-supply rejection (102dB typical), making it suitable for voltage-follower configurations and DC-coupled analog stages where input offset drift and supply ripple immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz - enables stable unity-gain amplification up to 4MHz without external compensation. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - ensures minimal audible noise contribution in line-level audio paths. |
| THD+N | 0.0001% at 1kHz - meets high-fidelity requirements for professional audio signal chains. |
| Output voltage swing | ±14.1V into 10kΩ - delivers full dynamic range with ±15V supplies and headroom for transient peaks. |
| Common-mode input range | ±14V - allows direct interface with signals near supply rails in single-ended or differential topologies. |
| Supply current (both amps) | 5.6mA typical - balances low power consumption with high AC performance for continuous-duty audio use. |
| Slew rate | 2.2V/μs - supports clean reproduction of 20kHz full-scale sine waves without slew-induced distortion. |
Pinout & Package
RC4558P uses an 8-pin plastic dual in-line package (PDIP) with 9.81mm × 9.43mm footprint, designed for through-hole mounting and legacy board compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 output | Drives load directly; requires local bypass capacitor for stability in high-frequency applications. |
| 2 | Amplifier 1 inverting input | Accepts feedback network; sensitive to stray capacitance - keep trace short and shielded. |
| 3 | Amplifier 1 noninverting input | High-impedance node; route away from noisy traces to avoid CMRR degradation. |
| 4 | Negative supply (VCC–) | Reference for both amplifiers; must be decoupled with 0.1μF ceramic capacitor to ground. |
| 5 | Amplifier 2 noninverting input | Independent high-Z input; matches Pin 3 electrically for stereo or dual-path signal routing. |
| 6 | Amplifier 2 inverting input | Matches Pin 2 in gain/phase response; enables matched dual-channel filter or gain stages. |
| 7 | Amplifier 2 output | Electrically identical to Pin 1; supports interleaved layout for minimized crosstalk in PCB design. |
| 8 | Positive supply (VCC+) | Shared rail for both amplifiers; bypassing here suppresses supply-induced inter-channel coupling. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates risk of oscillation in standard gain configurations. |
| Gain and phase match between amplifiers | Enables accurate differential signaling and stereo channel tracking without calibration. |
| Wide common-mode input voltage range | ±14V allows direct connection to signals referenced to mid-supply or rail without level-shifting circuitry. |
| No latch-up under overvoltage conditions | Prevents catastrophic failure during input transients or power sequencing mismatches in multi-rail systems. |
| Low distortion and noise | 0.0001% THD+N + 6.5nV/√Hz noise floor maintains signal integrity in analog front-ends and active filters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532P | Higher slew rate (9V/μs), lower input noise (5nV/√Hz), but higher supply current (8mA). | Better suited for high-speed active crossovers; less optimal for low-power portable designs. | Select NE5532P when ultra-low noise and fast transient response outweigh power budget constraints. |
| LM833N | Identical pinout and supply range; slightly lower GBW (15MHz) and higher THD+N (0.002%). | Acceptable for cost-sensitive consumer audio where fidelity margin is relaxed. | Choose LM833N only if legacy LM833-based designs require drop-in replacement with verified layout compatibility. |
Compared with NE5532P and LM833N, RC4558P offers the best balance of low noise, low distortion, and moderate power consumption in PDIP-8 packaging - making it ideal for mid-tier professional and consumer audio equipment where thermal and space constraints permit through-hole assembly.

FAQ
What is the maximum supply voltage for RC4558P?
The absolute maximum supply voltage for RC4558P is ±18V, but the recommended operating range is ±5V to ±15V. Operation at ±18V risks permanent damage per TI's Absolute Maximum Ratings. For reliable long-term use in audio applications, RC4558P should be operated within ±15V, where its ±14.1V output swing and 0.0001% THD+N are fully specified and validated.
Does RC4558P require external compensation components?
No, RC4558P does not require external compensation components. It features internal frequency compensation optimized for unity-gain stability across its full operating temperature range. This design eliminates the need for external capacitors or resistors in standard noninverting or inverting configurations - simplifying layout and improving reliability in RC4558P-based audio circuits.
How does RC4558P compare to RC4558DR in terms of performance?
RC4558P (PDIP-8) and RC4558DR (SOIC-8) share identical electrical specifications - including 4MHz gain-bandwidth product, 6.5nV/√Hz noise, and 0.0001% THD+N - because they belong to the same silicon die family. The only differences are package-related: RC4558P supports through-hole assembly and has higher thermal resistance (106°C/W), while RC4558DR offers surface-mount compatibility and tighter thermal performance (120.2°C/W).
Can RC4558P operate from a single supply?
Yes, RC4558P can operate from a single supply, provided the input common-mode and output swing ranges remain within specification. For example, with +30V and GND supplies, the input must stay between 3V and 27V, and output swing is limited to ~0.5V to ~29.5V. Designers must bias inputs appropriately and verify headroom - RC4558P's wide common-mode range (±14V) supports such configurations when referenced to mid-supply.
What is the input offset voltage specification for RC4558P?
The input offset voltage for RC4558P is 0.3mV typical and 7.5mV maximum at 25°C, with a full-range maximum of 7.5mV across 0°C to 70°C. This parameter directly impacts DC accuracy in precision gain stages and active filters - for instance, in a noninverting amplifier with 100× gain, a 7.5mV offset produces up to 0.75V output error, necessitating calibration or AC coupling in sensitive applications using RC4558P.
