Product details
Overview
RC4558PWRE4 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 dual-channel performance are required.
For engineers reviewing the RC4558PWRE4 datasheet, RC4558PWRE4 pinout, RC4558PWRE4 application, or RC4558PWRE4 equivalent, this page provides verified specifications, TSSOP-8 package details, dual op-amp functional context, and real-world audio design implementation guidance - all grounded in TI's SLOS073H production data sheet (October 2024 revision).
Technical Context
The RC4558PWRE4 integrates two independent high-fidelity op-amps on a single die with internal frequency compensation, eliminating external stability components. Its wide common-mode input range (±14V) and latch-up immunity support robust voltage-follower and unity-gain buffer configurations in analog front-ends.
Each amplifier features matched gain and phase response, enabling precise differential signal generation and stereo channel processing. The device supports both dual-supply (±5V to ±15V) and single-supply operation, with rail-compatible input stage design and 2.2V/μs slew rate ensuring fidelity up to ~100kHz for audio-band signals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - enables stable closed-loop gain of 100 at 40kHz, suitable for full-range audio amplification without peaking. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - ensures minimal audible hiss in line-level preamplifier stages. |
| THD+N | 0.0001% at 1kHz, 3VRMS output - meets high-fidelity audio requirements for professional mixers and soundbars. |
| Output voltage swing | ±14.1V into 10kΩ - delivers >28Vpp dynamic range from ±15V supplies, preserving headroom in analog signal chains. |
| Common-mode rejection ratio | 94dB typical - suppresses power supply ripple and ground noise in balanced-input configurations. |
| Supply current (dual) | 5.6mA typical - enables low-power operation in multi-channel audio systems without thermal derating. |
| Slew rate | 2.2V/μs - supports clean transient response for 20kHz sine waves (required ≥1.26V/μs), minimizing slew-induced distortion. |
Pinout & Package
TSSOP-8 (PW) package: 3mm × 6.4mm body, 0.65mm pitch, exposed pad optional, RoHS-compliant, surface-mount compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OUT) | Amplifier 1 output | Drives external load or feedback network; capable of ±125mA short-circuit current. |
| 2 (1IN–) | Amplifier 1 inverting input | Accepts feedback signal; high-impedance node requiring guard ring layout for low-noise designs. |
| 3 (1IN+) | Amplifier 1 noninverting input | High-impedance signal input; common-mode range extends to ±14V, supporting rail-to-rail sensing. |
| 4 (VCC–) | Negative supply rail | Reference for dual-supply operation; must be bypassed with 0.1μF ceramic capacitor near pin. |
| 5 (2IN+) | Amplifier 2 noninverting input | Independent input for second channel; gain and phase match within 0.1dB/0.5° vs Amplifier 1. |
| 6 (2IN–) | Amplifier 2 inverting input | Supports inverting configuration; matched input bias current (80nA typ.) minimizes offset drift between channels. |
| 7 (2OUT) | Amplifier 2 output | Electrically isolated from 1OUT; crosstalk attenuation ≥120dB at 10kHz enables stereo separation. |
| 8 (VCC+) | Positive supply rail | Power source for both amplifiers; requires local 0.1μF ceramic decoupling to suppress PSRR-related noise. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation | Internally compensated for unity-gain stability across temperature and supply variations - eliminates risk of oscillation in standard gain configurations. |
| Low distortion + noise | 0.0001% THD+N and 6.5nV/√Hz noise enable transparent audio reproduction in line drivers and tone control circuits. |
| Matched dual-channel performance | Gain and phase tracking <0.1dB/0.5° ensures consistent stereo imaging and accurate differential signal generation. |
| Wide supply voltage range | Operates from ±5V to ±15V - supports legacy 12V audio systems and modern ±15V professional gear without redesign. |
| Latch-up immunity | Guaranteed no destructive latch-up under overvoltage or ESD stress - critical for field-repairable audio equipment reliability. |

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 10MHz GBW, 3.5nV/√Hz noise, but higher 8mA supply current and narrower ±22V abs max supply. | Better suited for ultra-low-noise microphone preamps; less optimal for battery-constrained portable audio. | Select NE5532DR when THD+N <0.00005% and bandwidth >8MHz are mandatory; verify PCB layout supports tighter decoupling. |
| TL072CDR | Lower 3MHz GBW, JFET input (50pA bias), higher 18V/μs slew rate, but 18nV/√Hz noise and no guaranteed latch-up immunity. | Preferred for high-impedance sensor interfaces; not recommended for low-distortion audio line stages. | Choose TL072CDR for high-Z source buffering where noise is secondary; avoid in THD-sensitive consumer audio paths. |
Compared with NE5532DR and TL072CDR, RC4558PWRE4 offers the best balance of audio-grade distortion (0.0001%), supply flexibility (±5V to ±15V), latch-up safety, and TSSOP-8 footprint - making it ideal for cost-sensitive, production-ready audio equipment where reliability and consistency outweigh marginal noise or speed gains.

FAQ
What is the maximum operating supply voltage for RC4558PWRE4?
The RC4558PWRE4 has an absolute maximum supply voltage rating of ±18V, but its recommended operating range is ±5V to ±15V per the datasheet. Operating at ±15V delivers full specified performance including ±14.1V output swing into 10kΩ and 0.0001% THD+N. Exceeding ±18V risks permanent damage due to junction breakdown, and operation outside the recommended range may degrade CMRR, PSRR, or noise performance.
Does RC4558PWRE4 require external compensation capacitors?
No, RC4558PWRE4 does not require external compensation capacitors. It features internal frequency compensation optimized for unity-gain stability across its full operating temperature and supply range. This eliminates the need for external components in standard non-inverting, inverting, or voltage-follower configurations - simplifying layout and improving reliability in production audio systems.
Is RC4558PWRE4 pin-compatible with other dual op-amps in TSSOP-8 packages?
RC4558PWRE4 uses the industry-standard TSSOP-8 pinout (pin 1 = OUT1, pin 2 = IN1–, pin 3 = IN1+, pin 4 = V–, pin 5 = IN2+, pin 6 = IN2–, pin 7 = OUT2, pin 8 = V+), matching NE5532DR, TL072CDR, and LM833N in the same package. However, electrical characteristics differ significantly - always verify gain, noise, and supply requirements before substitution.
What is the typical input offset voltage of RC4558PWRE4?
The typical input offset voltage of RC4558PWRE4 is 6mV at 25°C, with a maximum of 7.5mV over the full 0°C to 70°C operating range. This value is measured under open-loop conditions with zero common-mode input voltage. For precision DC-coupled applications, system-level trimming or AC coupling may be required to mitigate offset impact.
How does RC4558PWRE4 perform in single-supply configurations?
RC4558PWRE4 supports single-supply operation by biasing inputs and outputs around mid-rail (e.g., VCC/2). Its common-mode input range extends to within 1.5V of either rail, and output swing reaches within 1.2V of each rail under light loads. When used with proper decoupling and reference generation, it functions reliably in 5V–30V single-rail audio line drivers and active filters.
