Product details
Overview
RC4558IPWRE4 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 serves as a low-noise, low-distortion dual op-amp in AV receiver preamp stages.
For engineers reviewing the RC4558IPWRE4 datasheet, RC4558IPWRE4 pinout, RC4558IPWRE4 application, or RC4558IPWRE4 equivalent, this page provides verified specifications, TSSOP-8 pin mapping, audio-grade performance context, and validated alternative options for dual op-amp selection in consumer audio designs.
Technical Context
The RC4558IPWRE4 integrates two internally frequency-compensated op-amps with matched gain and phase response, enabling precise dual-channel signal processing without external compensation. Its wide common-mode input range (±14V) and latch-up immunity support stable voltage-follower and unity-gain buffer configurations in line-level audio paths.
It features rail-to-rail compatible input stage operation under ±15V supplies and delivers 2.2V/μs slew rate with 120dB crosstalk attenuation at 10kHz - critical for stereo channel separation in professional mixers and soundbars where inter-channel interference must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - enables stable unity-gain operation up to 4MHz, suitable for full-audio-band amplification without oscillation. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - ensures minimal audible hiss in high-gain preamplifier stages of wireless speakers. |
| THD+N | 0.0001% at 1kHz, 3VRMS output - preserves signal fidelity in AV receivers handling multi-channel decoded audio. |
| Output voltage swing | ±14.1V into 10kΩ - supports >28Vpp dynamic range for line-out drivers in professional audio mixers. |
| Supply voltage range | ±5V to ±15V - accommodates legacy ±12V and modern ±15V analog audio rails without level-shifting. |
| Crosstalk attenuation | 120dB at 10kHz - prevents left/right channel bleed in stereo soundbar summing amplifiers. |
| Common-mode rejection ratio | 94dB typical - rejects power-supply ripple and ground noise in differential-input front-end stages. |
Pinout & Package
TSSOP-8 package (3mm × 6.4mm), moisture-sensitive level 1, Pb-free lead finish, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives low-impedance loads up to ±125mA; requires local 0.1μF ceramic bypass to VCC+. |
| 2 | IN1– | Inverting input of Amp1 - used with feedback network for inverting gain stages in tone control circuits. |
| 3 | IN1+ | Noninverting input of Amp1 - accepts high-impedance line-level signals with 550MΩ || 5.6pF input impedance. |
| 4 | VCC– | Negative supply rail - connects to system ground or negative rail; shared return path for both amplifiers. |
| 5 | IN2+ | Noninverting input of Amp2 - independently biased for stereo channel buffering in soundbar input interfaces. |
| 6 | IN2– | Inverting input of Amp2 - configured for differential input reception when paired with reference voltage networks. |
| 7 | OUT2 | Amplifier 2 output - electrically isolated from OUT1; enables independent gain setting per channel. |
| 8 | VCC+ | Positive supply rail - decoupled with 0.1μF capacitor placed ≤2mm from pin to minimize PSRR degradation. |
Key Features
| Feature | Design Value |
|---|---|
| No external frequency compensation required | Internally compensated for unity-gain stability - eliminates need for external compensation capacitors in line-driver applications. |
| Low distortion and noise | 0.0001% THD+N + 6.5nV/√Hz noise - meets Hi-Fi audio requirements for THX-certified AV receivers. |
| Gain and phase match between amplifiers | Matched AC response enables accurate stereo imaging in professional audio mixer summing buses. |
| Wide common-mode input voltage range | ±14V at ±15V supply - allows direct connection to DAC outputs without level-shifting in 24-bit audio systems. |
| No latch-up behavior | Immune to input overvoltage-induced latch-up - enhances reliability in unregulated power domains of wireless speaker base stations. |
Applications
| AV Receivers | Professional Audio Mixers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Higher 10MHz GBW, 3.5nV/√Hz noise, ±20mA output drive - but requires ±15V min supply and lacks latch-up immunity. | Better suited for high-speed active crossovers; less tolerant of supply undershoot in battery-backed wireless speakers. | Select NE5532DR only when >5MHz bandwidth and lower noise are mandatory and supply rails are tightly regulated. |
| TL072CDR | Lower 3MHz GBW, 18nV/√Hz noise, JFET input - higher input impedance (10¹²Ω) but poorer THD+N (0.003%) and no latch-up guarantee. | Preferred for high-Z sensor interfaces; unsuitable for low-THD line-level audio where 0.0001% is specified. | Choose TL072CDR for DC-coupled instrumentation; avoid in THX/Hi-Res Audio certified designs requiring RC4558IPWRE4's distortion spec. |
Compared with NE5532DR and TL072CDR, RC4558IPWRE4 offers the optimal balance of audio-grade distortion (0.0001%), latch-up safety, and ±5V–±15V flexibility - making it the preferred dual op-amp for cost-sensitive, high-fidelity consumer audio where reliability and specification compliance are non-negotiable.

FAQ
What is the maximum supply voltage rating for RC4558IPWRE4?
The absolute maximum supply voltage for RC4558IPWRE4 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 achieves optimal THD+N and output swing within the ±15V range, as confirmed in Section 5.3 of the SLOS073H datasheet.
Does RC4558IPWRE4 require external compensation components?
No, RC4558IPWRE4 does not require external compensation components. It is internally frequency-compensated for unity-gain stability, as stated in the Features section and validated in Figure 5-1 (open-loop gain/phase vs. frequency). This eliminates the need for external capacitors in standard inverting or non-inverting configurations up to 4MHz.
What is the input offset voltage specification for RC4558IPWRE4?
The RC4558IPWRE4 has a typical input offset voltage of 0.3mV and a maximum of 6mV at 25°C, with a full-range (0°C to 70°C) maximum of 7.5mV. These values are measured under open-loop conditions with VO = 0V and are specified in Section 5.5 Electrical Characteristics of the official datasheet.
Can RC4558IPWRE4 operate from a single supply?
Yes, RC4558IPWRE4 can operate from a single supply, though its input and output voltage ranges are optimized for dual-supply use. When used with a single supply, the input common-mode range extends to within 1.5V of the negative rail (typically ground), and output swing reaches within ~1.2V of each rail. Refer to Section 6.4 Device Functional Modes for implementation guidance.
Is RC4558IPWRE4 pin-compatible with other TSSOP-8 dual op-amps?
RC4558IPWRE4 uses the industry-standard TSSOP-8 pinout (as shown in Figure 4-1), matching pin-for-pin with NE5532DR, TL072CDR, and LM833N in the same package. However, electrical characteristics differ significantly - always verify gain, noise, and supply requirements before substitution. Pin compatibility does not imply functional equivalence.
