Product details
Overview
RC4558IPW from Texas Instruments is a dual general-purpose operational amplifier in TSSOP-8 package, delivering 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 internal frequency compensation for unity-gain stability - deployed in professional audio mixers and AV receivers.
For engineers reviewing the RC4558IPW datasheet, RC4558IPW pinout, RC4558IPW application, or RC4558IPW equivalent, key selection criteria include dual-channel matching, rail-compatible common-mode range (±14V), low-noise audio signal conditioning, and ±5V to ±15V dual-supply operation without external compensation components.
Technical Context
The RC4558IPW integrates two independent high-fidelity op-amps sharing a single silicon die, with matched gain and phase response enabling stereo channel synchronization. Its internal compensation eliminates need for external capacitors across all gains ≥1, supporting stable noninverting and inverting configurations up to 4MHz.
Designed for dual-supply audio front-ends, it accepts ±5V to ±15V rails and delivers ±14.1V output swing into 10kΩ while maintaining 94dB CMRR and 830V/mV open-loop gain. The absence of latch-up and wide common-mode input range (±14V) support robust voltage-follower and active filter implementations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - enables stable unity-gain amplification up to 4MHz without external compensation |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - supports low-noise preamplifier stages in high-fidelity audio paths |
| THD+N | 0.0001% at 1kHz, 3VRMS, RL = 2kΩ - ensures minimal harmonic distortion in line-level audio processing |
| Output voltage swing | ±14.1V into 10kΩ - provides headroom for ±12V signal handling in consumer and pro-audio equipment |
| Common-mode input range | ±14V - allows direct interface with signals referenced to mid-rail in single-supply systems |
| Supply current (both amps) | 5.6mA typical - enables dual-channel amplification within 10mW per channel at ±15V |
| Slew rate | 2.2V/μs - supports full-scale transient response for 20kHz audio signals without 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 | OUT1 | Amplifier 1 output - drives loads up to ±125mA, requires local 0.1μF bypass to VCC+ |
| 2 | IN1− | Inverting input of Amp1 - forms feedback node in inverting configurations; sensitive to PCB layout parasitics |
| 3 | IN1+ | Noninverting input of Amp1 - accepts common-mode voltages up to ±14V relative to VCC− |
| 4 | VCC− | Negative supply rail - must be decoupled with 0.1μF ceramic capacitor near pin |
| 5 | IN2+ | Noninverting input of Amp2 - electrically isolated but thermally coupled to Amp1 for gain/phase matching |
| 6 | IN2− | Inverting input of Amp2 - shares same input bias current spec (80–500nA) as IN1− |
| 7 | OUT2 | Amplifier 2 output - crosstalk attenuation >120dB at 10kHz enables independent channel operation |
| 8 | VCC+ | Positive supply rail - connects to 0.1μF bypass capacitor; shared rail supports dual-supply symmetry |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532AP | Higher 10MHz GBW, 3.5nV/√Hz noise, ±20V supply max, DIP-8 only | Better suited for ultra-low-noise microphone preamps; not pin-compatible with RC4558IPW TSSOP-8 | Select NE5532AP when noise floor <4nV/√Hz is required and through-hole assembly is acceptable |
| TL072CDR | Lower 3MHz GBW, 18nV/√Hz noise, JFET input, SOIC-8 only | Higher input impedance (10¹²Ω) benefits high-Z sensor interfaces; less suitable for low-distortion audio line drivers | Choose TL072CDR for high-impedance source buffering where THD+N >0.003% is acceptable |
Compared with NE5532AP and TL072CDR, RC4558IPW offers optimal balance of audio-grade distortion (0.0001%), moderate noise (6.5nV/√Hz), TSSOP-8 footprint, and guaranteed dual-channel matching - making it preferred for space-constrained stereo line-level signal chains requiring production consistency.

FAQ
What supply voltage range does the RC4558IPW support?
The RC4558IPW operates from ±5V to ±15V dual supplies, with absolute maximum ratings of ±18V. It is not rated for single-supply operation below ±5V; however, mid-rail biasing enables use with 10V–30V total supply span. The RC4558IPW maintains specified performance across this full recommended range, including 0.0001% THD+N and 6.5nV/√Hz noise at ±15V.
Is the RC4558IPW pin-compatible with other dual op-amps in TSSOP-8?
No - the RC4558IPW uses standard dual-op-amp pinout (OUT1, IN1−, IN1+, VCC−, IN2+, IN2−, OUT2, VCC+), but it is not pin-compatible with industry-standard alternatives like TL072 or NE5532 due to differing package offerings (TL072CDR is SOIC-8; NE5532AP is PDIP-8). The RC4558IPW TSSOP-8 footprint requires dedicated layout; no drop-in replacement exists in identical PW package.
Does the RC4558IPW require external frequency compensation?
No - the RC4558IPW features internal frequency compensation optimized for unity-gain stability. It remains stable in noninverting and inverting configurations with gain ≥1 without external capacitors. This eliminates layout sensitivity and reduces bill-of-materials cost. The RC4558IPW achieves 4MHz gain-bandwidth product while maintaining phase margin >60° across all recommended operating conditions.
How does the RC4558IPW perform in terms of channel matching?
The RC4558IPW provides guaranteed gain and phase matching between its two amplifiers due to monolithic integration on a single die. Electrical characteristics such as input offset voltage (max 7.5mV), input bias current (max 800nA), and slew rate (min 1.1V/μs) are characterized for both channels simultaneously. This matching enables precise stereo signal processing and differential driver applications where inter-channel coherence is critical - a key differentiator of the RC4558IPW versus discrete dual-op-amp solutions.
What thermal considerations apply to the RC4558IPW in TSSOP-8 package?
The RC4558IPW in PW (TSSOP-8) package has RθJA = 173.1°C/W and RθJB = 112.5°C/W. At 5.6mA quiescent current and ±15V supplies, power dissipation is ~170mW, resulting in ~30°C junction rise above ambient in still air. For continuous operation above 70°C ambient, PCB copper area under the exposed pad (if used) and airflow must be optimized. Thermal derating is required above 70°C ambient per TI's recommended operating conditions - the RC4558IPW is specified for 0°C to 70°C commercial temperature range.
