Product details
Overview
RC4558PWR from Texas Instruments is a dual general-purpose operational amplifier in an 8-pin TSSOP package, designed for audio signal conditioning with ±15V supply capability, 4MHz gain-bandwidth product, 6.5nV/√Hz input voltage noise at 10kHz, and 0.0001% THD+N at 1kHz - deployed in AV receivers and professional audio mixers.
For engineers reviewing the RC4558PWR datasheet, RC4558PWR pinout, RC4558PWR application, or RC4558PWR equivalent, this page delivers verified electrical specs, dual-amplifier pin mapping, low-noise audio design context, thermal performance data, and validated alternative options for industrial and consumer audio systems.
Technical Context
The RC4558PWR integrates two independent high-common-mode-input op-amps with internal frequency compensation, enabling stable unity-gain operation without external components. Its ±14.1V output swing (RL = 10kΩ) and 94dB CMRR support precision voltage-follower and differential-output configurations.
It operates across ±5V to ±15V supplies with 5.6mA total quiescent current, 2.2V/μs slew rate, and 120dB crosstalk attenuation at 10kHz - ensuring channel isolation and linearity in multi-stage audio amplification paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - enables stable closed-loop gain up to 400 at 10kHz for mid-band audio filtering. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - preserves signal integrity in preamplifier stages before ADC or power amplification. |
| THD+N | 0.0001% at 1kHz, 3VRMS - meets high-fidelity requirements for soundbars and wireless speakers. |
| Common-mode input range | ±14V - supports rail-to-rail input operation within ±15V supplies, critical for DC-coupled audio paths. |
| Output voltage swing | ±14.1V (RL = 10kΩ) - delivers full dynamic range into high-impedance loads without clipping. |
| Slew rate | 2.2V/μs - handles transient peaks in music signals up to ~350kHz without distortion. |
| Crosstalk attenuation | 120dB at 10kHz - prevents inter-channel leakage in stereo/multi-channel mixer applications. |
Pinout & Package
RC4558PWR uses an 8-pin TSSOP (PW) package measuring 3mm × 6.4mm, optimized for compact audio PCB layouts with thermal resistance RθJA = 173.1°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of first amplifier - drives downstream gain stage or filter network. |
| 2 | IN1– | Inverting input of first amplifier - accepts feedback for configured gain or inversion. |
| 3 | IN1+ | Noninverting input of first amplifier - connects to signal source or reference in buffer configuration. |
| 4 | VCC– | Negative supply rail - must be decoupled with 0.1μF ceramic capacitor near pin. |
| 5 | IN2+ | Noninverting input of second amplifier - used for independent channel processing. |
| 6 | IN2– | Inverting input of second amplifier - enables differential output generation with matched gain. |
| 7 | OUT2 | Output of second amplifier - pairs with OUT1 for balanced output or stereo signal path. |
| 8 | VCC+ | Positive supply rail - requires local 0.1μF bypass to suppress supply-induced noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates layout-sensitive compensation networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Higher slew rate (9V/μs), lower input noise (5nV/√Hz), but wider SOIC-8 package (6.2mm × 7.8mm). | Better suited for high-slew-demand applications like active crossovers; less optimal for ultra-low-power portable designs. | Select NE5532DR when higher bandwidth and lower noise are prioritized over quiescent current and board area. |
| TL072CDR | JFET-input architecture, higher input impedance (>10¹²Ω), but higher input voltage noise (18nV/√Hz at 1kHz). | Preferred for high-impedance sensor interfaces; not recommended for low-noise audio line-level stages. | Choose TL072CDR only for applications requiring ultra-high input Z, accepting trade-offs in noise and THD+N. |
Compared with RC4558PWR, NE5532DR offers superior dynamic performance at higher power and larger footprint, while TL072CDR trades noise and distortion for JFET input benefits - making RC4558PWR the balanced choice for cost-sensitive, space-constrained audio signal chains requiring proven THD+N and noise specs.

FAQ
What is the maximum supply voltage for RC4558PWR?
The RC4558PWR has absolute maximum supply ratings of ±18V, but its recommended operating range is ±5V to ±15V. Operating beyond ±15V risks exceeding thermal limits and degrading long-term reliability. The RC4558PWR achieves optimal THD+N and output swing performance within the ±15V specification, and all published electrical characteristics assume VCC+ = +15V and VCC− = −15V.
Does RC4558PWR require external compensation capacitors?
No, the RC4558PWR features internal frequency compensation and is stable at unity gain without external components. This eliminates layout sensitivity and saves board space in compact audio designs. The RC4558PWR's 4MHz gain-bandwidth product is specified under open-loop conditions with zero external compensation, and TI confirms stability across all standard closed-loop configurations up to G = 100.
What is the input offset voltage specification for RC4558PWR?
The RC4558PWR has a typical input offset voltage of 6mV and a maximum of 7.5mV over the 0°C to 70°C temperature range. At room temperature (25°C), the typical value is 0.3mV. This parameter directly impacts DC accuracy in summing or integrator circuits - for example, in a noninverting amplifier with G = 100, a 6mV offset produces up to 0.6V output error, necessitating calibration or AC coupling in precision applications.
How does RC4558PWR perform in terms of power supply rejection?
The RC4558PWR exhibits 92dB typical PSRR at 1kHz, improving to >100dB below 100Hz. This means that 100mV of ripple on the ±15V supply contributes less than 10µV of error at the output - critical for maintaining SNR in noisy switch-mode power supply environments. The RC4558PWR's PSRR remains effective across its full operating temperature range, supporting robust performance in thermally varying audio enclosures.
Can RC4558PWR be used in single-supply configurations?
Yes, the RC4558PWR supports single-supply operation with appropriate biasing - for example, using a mid-rail virtual ground at VCC/2. Its wide common-mode input range (±14V) and output swing (±14.1V into 10kΩ) allow it to function effectively with 30V total supply (e.g., 0V to +30V). In such setups, the RC4558PWR maintains 0.0001% THD+N and 6.5nV/√Hz noise, provided input signals remain within the valid common-mode window and output load is properly referenced.
