Product details
Overview
RC4558PWRG4 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 is used in professional audio mixers and AV receivers where low distortion and matched channel performance are critical.
For engineers reviewing the RC4558PWRG4 datasheet, RC4558PWRG4 pinout, RC4558PWRG4 application, or RC4558PWRG4 equivalent, key selection criteria include dual-channel matching, wide common-mode input range (±14V), no external frequency compensation requirement, thermal performance in TSSOP-8, and compatibility with ±15V audio signal chains.
Technical Context
The RC4558PWRG4 integrates two independent high-fidelity op-amps on a single die, each featuring internally compensated unity-gain-stable architecture and rail-to-rail input stage operation within ±14V common-mode range. Its differential input structure supports both inverting and non-inverting configurations without latch-up risk.
It exhibits 94dB common-mode rejection ratio and 86dB power-supply rejection ratio at 25°C, enabling stable operation in noisy supply environments. The device's 2.2V/μs slew rate and 3MHz small-signal bandwidth support faithful reproduction of audio signals up to 20kHz with minimal phase shift.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz - ensures stable unity-gain operation and sufficient loop gain for audio filters up to 20kHz. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - enables low-noise preamplification in line-level audio stages. |
| THD+N | 0.0001% at 1kHz - meets high-fidelity requirements for professional audio mixing and playback. |
| Output voltage swing | ±14.1V into 10kΩ - provides headroom for ±12V signal rails in analog audio circuits. |
| Common-mode input range | ±14V - supports direct coupling in voltage-follower and summing applications without level-shifting. |
| Supply voltage range | ±5V to ±15V - compatible with standard dual-rail audio power supplies and industrial control systems. |
| Slew rate | 2.2V/μs - preserves transient fidelity for fast-rising audio transients without slewing-induced distortion. |
Pinout & Package
TSSOP-8 package (PW), 3mm × 6.4mm body, exposed pad optional, rated for 0°C to 70°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives external load or feedback network; capable of ±125mA short-circuit current. |
| 2 | IN1− | Inverting input of Amp 1 - accepts feedback signal or inverted input; high-impedance node requiring guard ring layout. |
| 3 | IN1+ | Non-inverting input of Amp 1 - accepts reference or buffered signal; common-mode range extends to ±14V. |
| 4 | VCC− | Negative supply rail - must be decoupled with 0.1μF ceramic capacitor placed <2mm from pin. |
| 5 | IN2+ | Non-inverting input of Amp 2 - electrically isolated from Amp 1 inputs; enables independent dual-channel design. |
| 6 | IN2− | Inverting input of Amp 2 - supports matched gain-setting resistors for stereo channel alignment. |
| 7 | OUT2 | Amplifier 2 output - provides second channel output with <0.1dB gain match and <0.5° phase match to OUT1. |
| 8 | VCC+ | Positive supply rail - shared supply for both amplifiers; requires local 0.1μF bypass to ground. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates need for external compensation capacitors in standard configurations. |
| Low distortion and noise | 0.0001% THD+N + 6.5nV/√Hz noise - preserves dynamic range and clarity in line-stage amplification and active filters. |
| Gain and phase match between amplifiers | Matched AC performance enables true stereo signal paths without channel imbalance or crosstalk-induced imaging errors. |
| Wide common-mode input voltage range | ±14V - allows direct connection to sensor outputs or DACs operating near supply rails without attenuation or level shifting. |
| No latch-up | CMOS-compatible input stage prevents destructive latch-up during overvoltage or ESD events - improves system reliability in live audio environments. |

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 bias current (300nA typ), but higher quiescent current (8mA vs 5.6mA). | Better suited for high-speed active filters and headphone drivers; less optimal for low-power battery-backed audio interfaces. | Select NE5532DR when higher output drive and faster settling are required; RC4558PWRG4 remains preferred for cost-sensitive, thermally constrained designs. |
| TL072CDR | Lower noise (18nV/√Hz), JFET input (higher input impedance), but narrower common-mode range (±12V) and no guaranteed latch-up immunity. | Preferred for high-Z sensor interfaces and guitar effects; unsuitable for ±15V voltage-follower applications demanding rail-to-rail CMVR. | Choose TL072CDR for ultra-high-impedance sources; RC4558PWRG4 is superior for robustness and matched dual-channel performance in consumer audio. |
Compared with NE5532DR and TL072CDR, RC4558PWRG4 offers the best balance of low noise, wide common-mode range, latch-up immunity, and thermal efficiency in TSSOP-8 - making it ideal for mainstream audio equipment where reliability and channel matching outweigh peak speed or ultra-low bias current.

FAQ
What is the maximum supply voltage for RC4558PWRG4?
The absolute maximum supply voltage for RC4558PWRG4 is ±18V, but the recommended operating range is ±5V to ±15V. Operation beyond ±15V risks exceeding thermal limits and degrading long-term reliability. The device's electrical specifications - including output swing, THD+N, and CMRR - are guaranteed only within the ±5V to ±15V range per the datasheet's Recommended Operating Conditions table.
Does RC4558PWRG4 require external compensation components?
No, RC4558PWRG4 does not require external compensation components. It features internal frequency compensation optimized for unity-gain stability across its full operating temperature and supply range. This eliminates the need for external capacitors in standard inverting, non-inverting, and voltage-follower configurations - simplifying PCB layout and reducing bill-of-materials cost.
What is the typical input offset voltage of RC4558PWRG4?
The typical input offset voltage of RC4558PWRG4 is 6mV at 25°C, with a maximum of 7.5mV over the full 0°C to 70°C operating range. This parameter is measured under open-loop conditions with zero common-mode input voltage and is specified in the Electrical Characteristics table. Offset voltage drift versus temperature is characterized in Figure 5-19 of the datasheet.
Can RC4558PWRG4 be used in single-supply applications?
Yes, RC4558PWRG4 can be used in single-supply applications, though its input common-mode range does not extend to the negative rail. When operated from a single +30V supply (with VCC− grounded), the input common-mode range is 0V to +16V, and output swing reaches +26V. Proper biasing of input signals and use of rail-splitting networks or reference voltages are required to maintain linear operation.
What is the thermal resistance (RθJA) of the RC4558PWRG4 package?
The junction-to-ambient thermal resistance (RθJA) of RC4558PWRG4 in its TSSOP-8 (PW) package is 173.1°C/W, as specified in the Thermal Information table. This value assumes standard JEDEC 2-layer board conditions. For reliable operation at maximum ambient temperature, power dissipation must be limited to ensure junction temperature stays below 150°C - typically requiring <300mW total dissipation at 70°C ambient.
