Product details
Overview
RC4558IPWRG4 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 (RL = 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 RC4558IPWRG4 datasheet, RC4558IPWRG4 pinout, RC4558IPWRG4 application, or RC4558IPWRG4 equivalent, key selection criteria include dual-channel matching, wide common-mode input range (±14V), no external frequency compensation requirement, internal unity-gain stability, and SOIC-8 packaging compatibility with legacy audio designs.
Technical Context
The RC4558IPWRG4 integrates two independent high-fidelity op-amps on a single die, each featuring internally compensated dominant-pole architecture enabling stable unity-gain operation without external components. Its input stage supports rail-to-rail common-mode voltage (±14V) and exhibits no latch-up under overvoltage conditions.
Each amplifier provides 830 V/mV (94 dB) large-signal voltage gain, 94 dB CMRR, 2.2 V/μs slew rate, and 120 dB crosstalk attenuation at 10kHz - enabling precise differential signal generation and low-interference stereo channel processing in analog audio paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4 MHz - enables stable closed-loop operation up to 100 kHz at gain ≥ 40, suitable for full-audio-band filtering and buffering. |
| Input voltage noise density | 6.5 nV/√Hz at 10 kHz - ensures minimal audible hiss in line-level preamplifier and tone-control stages. |
| THD+N | 0.0001% at 1 kHz, 3 VRMS, RL = 2 kΩ - meets high-fidelity audio requirements for consumer and prosumer equipment. |
| Output voltage swing | ±14.1 V (RL = 10 kΩ) - supports >28 VPP dynamic range into high-impedance loads, preserving headroom in 30 V supply systems. |
| Common-mode input range | ±14 V - allows direct interface with ±12 V reference circuits and DC-coupled sensor outputs without level-shifting. |
| Slew rate | 2.2 V/μs - prevents slew-induced distortion on transients up to ~350 kHz at unity gain, covering full audio spectrum. |
| Supply current (both amps) | 5.6 mA typical (±15 V) - enables dual-channel amplification with <60 mW quiescent power, suitable for thermally constrained PCBs. |
Pinout & Package
RC4558IPWRG4 is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with 4.9 mm × 6.0 mm footprint, surface-mount compatible, and rated for industrial temperature range (0°C to 70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OUT) | Amplifier 1 output | Low-impedance buffered output capable of sourcing/sinking ±125 mA; requires local 0.1 µF bypass capacitor. |
| 2 (1IN–) | Amplifier 1 inverting input | Differential input node; sensitive to layout parasitics - must be routed short and away from noisy traces. |
| 3 (1IN+) | Amplifier 1 noninverting input | High-impedance input (550 MΩ || 5.6 pF); accepts DC-coupled signals within ±14 V common-mode range. |
| 4 (VCC–) | Negative supply rail | Reference return for both amplifiers; must be decoupled independently from VCC+ to minimize ground bounce. |
| 5 (2IN+) | Amplifier 2 noninverting input | Matched to Pin 3; enables synchronous dual-channel operation such as stereo buffering or differential driver pairs. |
| 6 (2IN–) | Amplifier 2 inverting input | Matched to Pin 2; supports identical feedback network design across both channels for gain and phase alignment. |
| 7 (2OUT) | Amplifier 2 output | Electrically isolated from Pin 1; 120 dB crosstalk attenuation enables independent signal paths without coupling. |
| 8 (VCC+) | Positive supply rail | Accepts ±5 V to ±15 V dual supply; absolute max rating ±18 V - exceeding risks permanent damage. |
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. |
| Gain and phase match between amplifiers | Typical channel-to-channel gain mismatch <0.1 dB and phase deviation <0.5° - critical for stereo imaging and balanced output generation. |
| Wide common-mode input voltage range | ±14 V at ±15 V supply - enables direct connection to ±12 V DAC outputs or op-amp-based level shifters without attenuation. |
| No latch-up behavior | Immune to input overvoltage-induced latch-up - improves reliability in systems with hot-plug or transient-prone signal sources. |
| Low distortion and noise | 0.0001% THD+N + 6.5 nV/√Hz noise floor - preserves signal integrity in high-resolution audio signal chains up to 24-bit/192 kHz playback. |

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 (9 V/μs), lower input noise (5 nV/√Hz), but higher supply current (8 mA) and narrower common-mode range (±12 V). | Better suited for high-speed active filters and low-impedance line drivers; less tolerant of wide common-mode excursions. | Select NE5532DR when higher bandwidth and lower noise outweigh power and common-mode constraints. |
| LM833N | Identical pinout and basic specs (4 MHz GBW, 0.0001% THD+N), but wider operating temperature range (−40°C to +85°C) and higher input bias current (500 nA typical). | Preferred for automotive or extended-temperature industrial audio interfaces where ambient exceeds 70°C. | Choose LM833N for designs requiring industrial temperature qualification without layout changes. |
Compared with RC4558IPWRG4, NE5532DR offers superior speed and noise performance at higher quiescent power, while LM833N provides extended temperature capability with slightly degraded input bias characteristics - both require validation of common-mode and output swing margins in target circuitry.

FAQ
What supply voltage range does the RC4558IPWRG4 support?
The RC4558IPWRG4 operates from ±5 V to ±15 V dual supplies, with absolute maximum ratings of ±18 V. Operation outside this range risks permanent damage. The device maintains specified performance across the full recommended range, including 30 V total supply (±15 V), and supports stable operation down to ±5 V for low-power audio monitoring applications. RC4558IPWRG4 data sheet Section 5.3 confirms these limits.
Does the RC4558IPWRG4 require external frequency compensation?
No, the RC4558IPWRG4 features internal frequency compensation optimized for unity-gain stability, eliminating the need for external compensation capacitors in standard inverting, noninverting, or voltage-follower configurations. This simplifies board layout and reduces BOM count. RC4558IPWRG4 datasheet Section 6.3.1 and Figure 5-2 confirm stable closed-loop response up to 4 MHz without added components.
What is the input voltage noise specification for RC4558IPWRG4?
The RC4558IPWRG4 has a typical input voltage noise density of 6.5 nV/√Hz at 10 kHz and 7 nV/√Hz at 1 kHz, with 0.38 µVPP integrated noise from 0.1 Hz to 10 Hz. These values are measured under standard conditions (±15 V supplies, TA = 25°C) and make RC4558IPWRG4 suitable for low-noise preamplifier and line-level audio stages where audible hiss must be minimized.
How does RC4558IPWRG4 perform in terms of channel matching?
The RC4558IPWRG4 provides tightly matched gain and phase between its two amplifiers, with typical crosstalk attenuation of 120 dB at 10 kHz and guaranteed gain-bandwidth and slew rate uniformity across channels. This matching ensures consistent stereo imaging and balanced differential signal generation - critical in applications like dual-channel tone control or active crossover networks using RC4558IPWRG4.
Is RC4558IPWRG4 suitable for single-supply operation?
Yes, the RC4558IPWRG4 can operate from a single supply (e.g., 10 V to 30 V) with appropriate input/output biasing, though its specified common-mode and output swing performance is optimized for dual-supply use. When used single-supply, designers must ensure input signals remain within the valid common-mode range (typically 3 V above VCC– and 3 V below VCC+) and implement proper DC offset handling. RC4558IPWRG4 datasheet Section 6.4 confirms functional single-supply capability.
