Product details
Overview
RC4558DRG4 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 audio equipment.
For engineers reviewing the RC4558DRG4 datasheet, RC4558DRG4 pinout, RC4558DRG4 application, or RC4558DRG4 equivalent, key selection criteria include its dual-channel matching, latch-up immunity, internal frequency compensation, wide common-mode input range (±14V), and suitability for voltage-follower and differential-output configurations without external compensation components.
Technical Context
The RC4558DRG4 integrates two independent op-amps on a single die with matched AC performance: gain-bandwidth product of 4MHz, slew rate of 2.2V/μs, and crosstalk attenuation of 120dB at 10kHz. Its internal frequency compensation ensures unity-gain stability without external capacitors.
It supports dual-supply operation from ±5V to ±15V, features rail-compatible common-mode input range (±14V), and exhibits low distortion (0.0001% THD+N) and low noise (6.5nV/√Hz), making it suitable for linear analog signal paths where channel-to-channel tracking and low-noise amplification are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz - enables stable closed-loop operation up to 100kHz at gain ≥40, sufficient for full-audio-band filtering and buffering. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - preserves signal integrity in microphone preamps and line-level stages without audible hiss. |
| THD+N | 0.0001% at 1kHz - ensures negligible harmonic and noise degradation in high-fidelity audio signal chains. |
| Output voltage swing | ±14.1V (RL = 10kΩ) - delivers >28Vpp headroom into high-impedance loads, supporting dynamic range in AV receivers and mixers. |
| Common-mode input range | ±14V - allows direct interface with signals referenced near supply rails, e.g., in active filters and DC-coupled buffers. |
| Supply current (both amps) | 5.6mA typical - enables low-power operation in multi-channel audio systems without excessive thermal load. |
| Crosstalk attenuation | 120dB at 10kHz - prevents inter-channel leakage in stereo processing, critical for panning and balance control accuracy. |
Pinout & Package
RC4558DRG4 is packaged in an 8-pin SOIC (D package), measuring 4.9mm × 6mm, with standard surface-mount footprint and gull-wing leads compatible with automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OUT) | Amplifier 1 output | Drives external load or feedback network; capable of ±14.1V swing into 10kΩ. |
| 2 (1IN–) | Amplifier 1 inverting input | Accepts feedback signal; high-impedance node requiring guard ring or short trace routing. |
| 3 (1IN+) | Amplifier 1 noninverting input | Accepts signal source; common-mode range extends to ±14V relative to VCC–/VCC+. |
| 4 (VCC–) | Negative supply rail | Reference for dual-supply operation; must be decoupled with 0.1μF ceramic capacitor near pin. |
| 5 (2IN+) | Amplifier 2 noninverting input | Independent input for second channel; matches 1IN+ in offset, noise, and CMRR performance. |
| 6 (2IN–) | Amplifier 2 inverting input | Feedback node for second amplifier; identical electrical characteristics to Pin 2. |
| 7 (2OUT) | Amplifier 2 output | Provides matched output drive; crosstalk attenuation >120dB isolates channels in stereo applications. |
| 8 (VCC+) | Positive supply rail | Power input 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 need for external compensation capacitor in standard configurations. |
| Low input voltage noise | 6.5nV/√Hz at 10kHz - enables clean amplification of low-level audio signals without adding measurable noise floor. |
| High channel-to-channel matching | Matched gain, phase, and distortion between amplifiers - ensures consistent stereo imaging and balanced tone control response. |
| Latch-up immunity | Guaranteed no latch-up under normal operating conditions - improves reliability in voltage-follower and high-CMVR applications. |
| Wide supply voltage range | Operates from ±5V to ±15V - supports legacy 15V audio rails and newer lower-voltage designs without performance compromise. |

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 GBW (10MHz), lower noise (5nV/√Hz), higher supply current (8mA), no latch-up guarantee stated | Better suited for ultra-low-noise microphone preamps; less tolerant of overvoltage transients | Select NE5532DR when bandwidth and noise performance outweigh latch-up robustness and power efficiency needs. |
| LM833N | Identical pinout and basic specs (4MHz GBW, 0.0001% THD+N), but wider temp range (–40°C to +85°C), higher max supply (±20V) | Preferred for industrial audio gear requiring extended temperature operation and higher rail tolerance | Choose LM833N for designs needing broader environmental qualification or margin beyond ±15V operation. |
Compared with NE5532DR and LM833N, RC4558DRG4 offers superior latch-up immunity and lower quiescent current, making it optimal for cost-sensitive, high-reliability consumer audio where ±15V rails and moderate bandwidth suffice - without demanding ultra-low noise or extended temperature grading.

FAQ
What is the maximum supply voltage for RC4558DRG4?
The absolute maximum supply voltage for RC4558DRG4 is ±18V, but the recommended operating range is ±5V to ±15V. Operation beyond ±15V risks exceeding thermal limits and degrading long-term reliability. The RC4558DRG4 datasheet specifies electrical characteristics only within the ±5V to ±15V range, and exceeding this may cause irreversible damage per Absolute Maximum Ratings.
Does RC4558DRG4 require external compensation capacitors?
No, RC4558DRG4 does not require external compensation capacitors. It is internally frequency-compensated for unity-gain stability, enabling stable operation in standard noninverting, inverting, and voltage-follower configurations without added components. This simplifies PCB layout and reduces bill-of-materials cost in audio signal paths.
What is the input common-mode voltage range of RC4558DRG4?
The input common-mode voltage range of RC4558DRG4 is ±14V under recommended operating conditions (±15V supplies), meaning both inputs can operate safely from –14V to +14V relative to ground. This wide range supports DC-coupled configurations and high-impedance sensor interfaces without level-shifting circuitry.
How does RC4558DRG4 perform in stereo audio applications?
RC4558DRG4 excels in stereo audio applications due to its 120dB crosstalk attenuation at 10kHz and matched gain/phase between amplifiers. This ensures precise left/right channel tracking in tone controls, active filters, and line drivers - preserving stereo imaging and preventing inter-channel signal leakage in AV receivers and soundbars.
Is RC4558DRG4 suitable for single-supply operation?
RC4558DRG4 is specified for dual-supply operation (±5V to ±15V) and is not optimized for true single-supply use. While it can function with a split-rail derived from a single supply (e.g., using virtual ground), its common-mode and output swing specifications assume symmetric rails. For native single-supply designs, consider rail-to-rail op-amps like TLV2462 instead of RC4558DRG4.
