Product details
Overview
RC4558PG4 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 into 10kΩ, and operates from ±5V to ±15V supplies. It serves as a low-noise, low-distortion dual op-amp in preamplifier and line-driver stages of consumer audio equipment.
For engineers reviewing the RC4558PG4 datasheet, RC4558PG4 pinout, RC4558PG4 application, or RC4558PG4 equivalent, key selection criteria include its dual-channel matching, wide common-mode input range (±14V), internal frequency compensation, rail-compatible output swing, and suitability for voltage-follower and noninverting amplifier configurations in analog audio signal paths.
Technical Context
The RC4558PG4 integrates two independent high-fidelity op-amps on a single die with matched AC performance: gain-bandwidth product is 4MHz, slew rate is 2.2V/μs, and crosstalk attenuation exceeds 120dB at 10kHz. Its internal frequency compensation eliminates external compensation components, enabling stable unity-gain operation.
It supports dual-supply operation from ±5V to ±15V with common-mode input range extending to ±14V and output swing reaching ±14.1V into 10kΩ. Input offset voltage is 6mV typical, input bias current is 500nA max, and CMRR is 94dB typical - all specified over 0°C to 70°C for the RC4558 variant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz - enables stable closed-loop operation up to 100kHz at gain ≥40, suitable for audio band amplification without external compensation. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - ensures minimal audible noise contribution in line-level audio preamplifier stages. |
| THD+N | 0.0001% at 1kHz, 3VRMS output - meets high-fidelity requirements for AV receivers and professional mixers. |
| Output voltage swing | ±14.1V into 10kΩ - provides >28Vpp dynamic range for full-scale analog audio signals with headroom. |
| Common-mode input range | ±14V - allows direct interface with ±12V-sourced sensor or DAC outputs without level-shifting. |
| Supply voltage range | ±5V to ±15V - supports legacy audio designs using ±12V or ±15V rails while maintaining specified performance. |
| Crosstalk attenuation | 120dB at 10kHz - prevents inter-channel signal leakage critical in stereo and multi-channel audio routing. |
Pinout & Package
RC4558PG4 is supplied in an 8-pin PDIP (Plastic Dual In-line Package) with 9.81mm × 9.43mm footprint, through-hole mounting, and standard 0.3-inch row spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 output | Low-impedance buffered output node for first op-amp channel; drives loads ≥2kΩ without instability. |
| 2 | Amplifier 1 inverting input | Inverts and sums input signals; requires matched feedback network for precision gain setting. |
| 3 | Amplifier 1 noninverting input | High-impedance input for reference or signal source; common-mode range extends to ±14V. |
| 4 | Negative supply (VCC–) | Reference return for both amplifiers; must be decoupled with 0.1μF ceramic capacitor near pin. |
| 5 | Amplifier 2 noninverting input | Independent high-Z input for second channel; electrically isolated from Channel 1 except via shared supply rails. |
| 6 | Amplifier 2 inverting input | Second inverting node; used for summing, filtering, or inverting gain configurations. |
| 7 | Amplifier 2 output | Second independent output; crosstalk < –120dB ensures channel separation in stereo applications. |
| 8 | Positive supply (VCC+) | Main power rail for both amplifiers; bypassing required to suppress supply-induced distortion. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates risk of oscillation in basic noninverting configurations. |
| Low input voltage noise | 6.5nV/√Hz at 10kHz - preserves signal-to-noise ratio in microphone preamp and phono stage interfaces. |
| Matched amplifier pair | Gain and phase match between channels - enables precise stereo balance and differential signal generation. |
| Wide common-mode input range | ±14V - accommodates input signals referenced to mid-rail or external bias points without clipping. |
| No latch-up behavior | Immune to input overvoltage-induced latch-up - enhances reliability in systems with transient-prone inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532AP | Higher slew rate (9V/μs), lower input noise (5nV/√Hz), but requires ±15V min supply; no internal compensation for gains < 5. | Better suited for high-speed active filters and ultralow-noise preamps; less tolerant of low-voltage or unity-gain use cases. | Select NE5532AP when higher bandwidth and lower noise are prioritized over supply flexibility and ease of use. |
| LM833N | Identical pinout and supply range; slightly lower GBW (15MHz), higher THD+N (0.002%), and reduced output swing (±12V). | Acceptable for cost-sensitive consumer audio where 0.002% distortion is acceptable; not recommended for pro-grade line drivers. | Choose LM833N only for legacy-replacement scenarios where PCB layout reuse is mandatory and performance margin is relaxed. |
Compared with NE5532AP and LM833N, RC4558PG4 offers superior supply voltage flexibility (±5V min), guaranteed unity-gain stability, and best-in-class crosstalk - making it optimal for dual-channel audio routing where channel isolation and design simplicity are critical.

FAQ
What is the maximum operating temperature range for the RC4558PG4?
The RC4558PG4 is rated for operation from 0°C to 70°C ambient temperature. This specification applies to the standard RC4558 variant (not the extended-temperature RC4558I). Electrical characteristics including input offset voltage, CMRR, and output swing are guaranteed across this range per the datasheet's Recommended Operating Conditions table.
Does the RC4558PG4 require external compensation capacitors?
No, the RC4558PG4 does not require external compensation capacitors. It features internal frequency compensation optimized for stable unity-gain operation. This eliminates the need for external components in standard noninverting and inverting amplifier configurations, reducing bill-of-materials count and layout complexity.
Can the RC4558PG4 operate from a single 12V supply?
Yes, the RC4558PG4 can operate from a single 12V supply when configured with appropriate input biasing and output coupling. The device supports single-supply operation per Section 6.4 of the datasheet; however, its specified common-mode and output swing performance is optimized for dual-supply use. For single-supply designs, input common-mode range and output headroom must be verified against the application's signal levels.
What is the typical input offset voltage for the RC4558PG4?
The typical input offset voltage for the RC4558PG4 is 6mV at 25°C, with a maximum of 7.5mV across the full 0°C to 70°C operating range. This value is measured under open-loop conditions with zero common-mode input voltage and is specified in Section 5.5 of the RC4558 datasheet (SLOS073H).
Is the RC4558PG4 pin-compatible with other dual op-amps in PDIP-8 packages?
The RC4558PG4 uses the industry-standard dual op-amp pinout (pin 1 = OUT1, pin 2 = IN1–, pin 3 = IN1+, pin 4 = V–, pin 5 = IN2+, pin 6 = IN2–, pin 7 = OUT2, pin 8 = V+), matching NE5532, LM833, and TL072. However, electrical differences - such as gain-bandwidth, noise, and output drive - mean functional substitution requires circuit validation even with identical pinouts.
