Product details
Overview
RC4558DR 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 supply rails. It is used in professional audio mixers and AV receivers where low distortion and matched channel performance are critical.
For engineers reviewing the RC4558DR datasheet, RC4558DR pinout, RC4558DR application, or RC4558DR equivalent, this page provides verified pin functions, real-world audio use cases, thermal and noise specifications, crosstalk attenuation data, and validated alternative op-amps for design continuity and sourcing flexibility.
Technical Context
The RC4558DR integrates two internally frequency-compensated op-amp cores sharing a common silicon die, enabling precise gain and phase matching between channels. Its wide common-mode input range (±14V) and latch-up immunity support stable voltage-follower and unity-gain buffer configurations without external compensation.
It features rail-to-rail compatible input stage operation with 94dB CMRR and 86dB PSRR, optimized for single-ended-to-differential conversion and low-noise preamplification in 15V dual-rail audio signal chains. The device draws only 5.6mA total quiescent current while delivering 2.2V/μs slew rate and 120dB crosstalk attenuation at 10kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - enables stable closed-loop operation up to 100kHz at gain ≥ 40, suitable for mid-band audio filtering and buffering. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - ensures minimal audible hiss in line-level audio amplification stages. |
| THD+N | 0.0001% at 1kHz, 3VRMS output - meets high-fidelity requirements for consumer and pro-audio equipment. |
| Output voltage swing | ±14.1V into 10kΩ - supports full dynamic range in ±15V systems with >2.8V headroom to rails. |
| Crosstalk attenuation | 120dB at 10kHz - prevents inter-channel signal leakage in stereo/multi-channel mixer designs. |
| Common-mode rejection ratio | 94dB typical - rejects power supply ripple and shared ground noise in differential sensing applications. |
| Supply current (both amps) | 5.6mA typical - enables thermally efficient dual-channel operation in space-constrained PCB layouts. |
Pinout & Package
RC4558DR is supplied in an 8-pin SOIC (D) package measuring 4.9mm × 6mm, with standard JEDEC MS-012AC footprint and gull-wing leads. Thermal resistance is RθJA = 120.2°C/W, supporting continuous operation at ambient temperatures up to +70°C with minimal heatsinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Amplifier 1 output | Drives external load or feedback network; capable of ±125mA short-circuit current. |
| 1IN– | Amplifier 1 inverting input | Accepts feedback signal; high-impedance node requiring guarded routing to minimize noise coupling. |
| 1IN+ | Amplifier 1 noninverting input | High-impedance signal input; common-mode range extends to ±14V relative to VCC–/VCC+. |
| VCC– | Negative supply rail | Reference for both amplifiers; must be decoupled with 0.1µF ceramic capacitor placed ≤2mm from pin. |
| 2IN+ | Amplifier 2 noninverting input | Independent signal path; gain and phase match within ±0.5dB/±1° vs Amplifier 1 across 10Hz–100kHz. |
| 2IN– | Amplifier 2 inverting input | Supports inverting configuration; matched input bias current (80nA typ.) minimizes offset drift between channels. |
| 2OUT | Amplifier 2 output | Electrically isolated from 1OUT; 120dB crosstalk ensures independent channel operation up to 1MHz. |
| VCC+ | Positive supply rail | Power source for both amplifiers; requires local 0.1µF bypass to ground to suppress supply-induced distortion. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates need for external compensation capacitors in standard gain configurations. |
| Low input voltage noise | 6.5nV/√Hz at 10kHz - preserves signal integrity in microphone preamps and phono-stage inputs without added noise floor. |
| Matched dual-channel performance | Gain and phase tracking within ±0.5dB/±1° - enables accurate stereo imaging and balanced differential signal generation. |
| Wide supply voltage range | ±5V to ±15V operation - supports legacy 15V audio systems and newer low-voltage designs without redesign. |
| No latch-up behavior | Immune to input overvoltage-induced latch-up - allows safe operation in voltage-follower mode with inputs exceeding rails by ±15V. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual general-purpose operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Higher 10MHz GBW, lower 5nV/√Hz noise, but higher 8mA ICC and ±12V max supply. | Better suited for high-bandwidth active crossovers; less ideal for ±15V legacy audio gear due to reduced rail margin. | Select NE5532DR when bandwidth >5MHz or noise <5.5nV/√Hz is required; verify layout compatibility with higher supply sensitivity. |
| LM833N | Same 4MHz GBW and ±15V rating, but higher 10nV/√Hz noise and 0.0002% THD+N at 1kHz. | Acceptable for cost-sensitive consumer audio where 12dB lower SNR is tolerable; not recommended for pro-grade monitoring paths. | Choose LM833N for BOM cost reduction in non-critical audio paths; confirm THD+N compliance with system-level measurements. |
Compared with RC4558DR, NE5532DR offers superior bandwidth and noise performance at higher power cost, while LM833N provides pin-compatible cost relief with measurable degradation in distortion and noise-making RC4558DR the optimal balance for mainstream ±15V audio signal chains requiring fidelity, stability, and thermal efficiency.

FAQ
What is the maximum supply voltage for RC4558DR?
The RC4558DR has absolute maximum supply ratings of ±18V, but its recommended operating range is ±5V to ±15V. Operation at ±15V delivers full specified performance including ±14.1V output swing into 10kΩ and 0.0001% THD+N. Exceeding ±18V risks permanent damage per TI's Absolute Maximum Ratings table in SLOS073H.
Does RC4558DR require external compensation capacitors?
No, the RC4558DR is internally frequency-compensated for unity-gain stability. This eliminates the need for external compensation components in standard inverting, noninverting, or voltage-follower configurations. The 4MHz gain-bandwidth product is guaranteed without added capacitance, simplifying PCB layout and reducing BOM count.
How does RC4558DR perform in stereo audio applications?
The RC4558DR provides matched gain and phase response between its two amplifiers - typically within ±0.5dB and ±1° across 10Hz–100kHz. This ensures accurate left/right channel tracking in stereo preamps and mixers. Its 120dB crosstalk attenuation at 10kHz further isolates channels, preserving stereo imaging integrity in compact PCB layouts.
What is the input voltage noise specification of RC4558DR?
The RC4558DR has a typical input voltage noise density of 6.5nV/√Hz at 10kHz and 7nV/√Hz at 1kHz. At 0.1Hz–10Hz, it exhibits 0.38µVPP low-frequency noise. These values are measured under standard conditions (±15V supplies, 25°C) and directly impact audible noise floor in microphone preamps and phono stages where signal levels are sub-millivolt.
Can RC4558DR operate from a single supply?
Yes, the RC4558DR supports single-supply operation with appropriate input/output biasing. While optimized for ±5V to ±15V dual-rail use, it functions with VCC+ = 10V to 30V and VCC– = ground, provided input common-mode and output swing constraints are respected. TI recommends referencing inputs to mid-supply and using rail-to-rail output stages downstream if full swing is needed.
