Product details
Overview
RC4558IDGKR from Texas Instruments is a dual general-purpose operational amplifier in an 8-pin VSSOP 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-compatible common-mode input range up to ±14V - deployed in professional audio mixers and AV receivers for low-distortion signal conditioning.
For engineers reviewing the RC4558IDGKR datasheet, RC4558IDGKR pinout, RC4558IDGKR application, or RC4558IDGKR equivalent, key selection criteria include dual-channel matching, wide supply range (±5V to ±15V), internal frequency compensation, low-noise audio-grade performance, and thermal robustness in compact VSSOP packaging.
Technical Context
The RC4558IDGKR integrates two independent high-fidelity op-amps with internally compensated unity-gain-stable architecture, enabling stable operation without external compensation components. Its differential pair input stage supports wide common-mode voltage range (±14V) and latch-up immunity, making it suitable for voltage-follower and active filter configurations.
Each amplifier features matched gain and phase response, crosstalk attenuation of 120dB at 10kHz, and 2.2V/μs slew rate - enabling accurate dual-channel signal processing in stereo audio paths and differential driver circuits where channel-to-channel consistency is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - enables stable closed-loop operation up to 100kHz with gain ≥40, supporting mid-band audio filtering and buffering. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - ensures minimal audible noise contribution in line-level preamplifier stages. |
| THD+N | 0.0001% at 1kHz, 3VRMS output - meets high-fidelity audio requirements for soundbars and wireless speakers. |
| Output voltage swing | ±14.1V into 10kΩ - delivers full dynamic range across ±15V supplies with <0.5V headroom loss. |
| Common-mode input range | ±14V - allows direct interfacing with ±12V sensor outputs or DAC references without level-shifting. |
| Supply current (both amps) | 5.6mA typical - enables low-power dual-channel amplification in battery-assisted audio accessories. |
| Crosstalk attenuation | 120dB at 10kHz - prevents inter-channel leakage in stereo summing and mixing applications. |
Pinout & Package
RC4558IDGKR uses an 8-pin VSSOP (DGK) package measuring 3mm × 4.9mm with exposed pad for thermal enhancement. Pin numbering follows standard SOIC/VSSOP top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 output | Low-impedance buffered output capable of sourcing/sinking ±125mA; requires local 0.1μF bypass to ground. |
| 2 | Amplifier 1 inverting input | Differential node for feedback networks; sensitive to PCB trace capacitance and layout-induced noise coupling. |
| 3 | Amplifier 1 noninverting input | High-impedance reference node; must be routed away from noisy supply or output traces to avoid CMRR degradation. |
| 4 | Negative supply (VCC–) | Return path for both amplifiers; connects to system ground or negative rail; shares thermal pad for junction cooling. |
| 5 | Amplifier 2 noninverting input | Independent high-Z input for second channel; matches pin 3 electrically and thermally for dual-path symmetry. |
| 6 | Amplifier 2 inverting input | Feedback node for second amplifier; identical electrical behavior to pin 2 for matched channel design. |
| 7 | Amplifier 2 output | Electrically isolated output stage; 120dB crosstalk attenuation ensures minimal interaction with pin 1 under dynamic load. |
| 8 | Positive supply (VCC+) | Power entry for both amplifiers; requires dedicated 0.1μF ceramic capacitor placed within 2mm of pin. |
Key Features
| Feature | Design Value |
|---|---|
| Internal frequency compensation | Enables unity-gain stability without external capacitors - reduces BOM count and layout sensitivity in audio buffer designs. |
| Channel-to-channel gain and phase match | Ensures consistent frequency response between amplifiers - critical for stereo imaging and differential signal generation. |
| No latch-up design | Prevents destructive current runaway during overvoltage transients - enhances reliability in unregulated audio power domains. |
| Wide supply voltage range | Operates from ±5V to ±15V - supports legacy ±12V systems and modern ±15V pro-audio rails without redesign. |
| Low input bias current | 80nA typical - minimizes DC error in high-impedance sensor interfaces and passive filter networks. |

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 noise (5nV/√Hz), but higher quiescent current (8mA) and no VSSOP option. | Better suited for high-speed active crossovers; less optimal for space-constrained portable audio due to SOIC-8 only. | Choose NE5532DR when THD+N <0.00005% and >100kHz small-signal bandwidth are required, accepting larger footprint and higher power. |
| TL072CDR | Lower cost, JFET-input (50pA IB), but higher noise (18nV/√Hz) and lower GBW (3MHz); not specified for ±15V operation. | Acceptable for non-critical consumer audio; unsuitable for professional-grade THD+N or wide common-mode range needs. | Choose TL072CDR only for cost-sensitive, low-performance line drivers where 0.002% THD+N is acceptable and supply is limited to ±12V. |
Compared with NE5532DR and TL072CDR, RC4558IDGKR offers the optimal balance of audio-grade linearity (0.0001% THD+N), compact VSSOP packaging, and ±15V compatibility - making it the preferred choice for space-constrained, dual-channel prosumer audio designs requiring verified low-noise performance without premium cost or thermal overhead.

FAQ
What is the maximum supply voltage rating for RC4558IDGKR?
The RC4558IDGKR has absolute maximum supply ratings of ±18V, but its recommended operating range is ±5V to ±15V. Operation beyond ±15V risks exceeding thermal limits and degrading long-term reliability, even if within absolute max. The RC4558IDGKR achieves optimal THD+N and output swing performance specifically at ±15V, where it delivers ±14.1V swing into 10kΩ loads.
Does RC4558IDGKR require external frequency compensation?
No, RC4558IDGKR does not require external frequency compensation. It features internal compensation optimized for unity-gain stability across its full operating temperature range (0°C to 70°C). This eliminates the need for external compensation capacitors in standard inverting, noninverting, or voltage-follower configurations - simplifying layout and reducing component count in RC4558IDGKR-based audio buffer designs.
What is the input offset voltage specification for RC4558IDGKR?
The RC4558IDGKR has a typical input offset voltage of 0.3mV, with a maximum of 6mV at 25°C and 7.5mV across the full 0°C to 70°C operating range. This low offset enables accurate DC-coupled signal paths in active filters and summing amplifiers without requiring manual nulling circuitry - a key advantage of RC4558IDGKR over older dual op-amp generations.
How does RC4558IDGKR perform in terms of channel crosstalk?
RC4558IDGKR provides 120dB crosstalk attenuation at 10kHz, measured with 1kΩ source resistance. This exceptional isolation results from die-level layout optimization and substrate decoupling, ensuring minimal signal leakage between channels in stereo applications. In practice, this means RC4558IDGKR maintains >100dB channel separation across the entire audio band, preserving stereo imaging integrity in professional audio mixer implementations.
Is RC4558IDGKR suitable for single-supply operation?
Yes, RC4558IDGKR supports single-supply operation with appropriate input biasing and output referencing. While optimized for dual ±5V to ±15V rails, it functions with a single 10V–30V supply when the input common-mode range and output swing are referenced to mid-rail (e.g., using resistor dividers or dedicated bias generators). The RC4558IDGKR's wide common-mode input range (±14V) and rail-compatible output swing make it adaptable to both architectures without performance compromise.
