Product details
Overview
RC4558IP from Texas Instruments is a dual general-purpose operational amplifier in 8-pin PDIP package, featuring ±15V supply operation, 4MHz gain-bandwidth product, 6.5nV/√Hz input voltage noise at 10kHz, 0.0001% THD+N at 1kHz, and rail-compatible common-mode input range up to ±14V - deployed in professional audio mixers and AV receivers for low-distortion signal conditioning.
For engineers reviewing the RC4558IP datasheet, RC4558IP pinout, RC4558IP application, or RC4558IP equivalent, this page delivers verified electrical specs, dual-amplifier pin mapping, audio-grade performance context, thermal derating guidance, and TI-validated alternative options for analog signal path design.
Technical Context
The RC4558IP integrates two internally frequency-compensated op-amps with matched gain and phase response, enabling stable unity-gain operation without external compensation. Its high common-mode input voltage range (±14V) and latch-up immunity support robust voltage-follower configurations in bipolar supply systems.
Each amplifier provides 2.2V/μs slew rate, 94dB CMRR, and 830V/mV large-signal open-loop gain - optimized for linear AC-coupled amplification in 20Hz–20kHz audio bands. Input bias current remains below 500nA across 0°C–70°C, ensuring minimal DC error in high-impedance sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4MHz typical - supports stable closed-loop gain ≥10 up to 400kHz, suitable for mid-band audio preamplification. |
| Input voltage noise density | 6.5nV/√Hz at 10kHz - enables <0.5µV RMS integrated noise in 20Hz–20kHz band with proper filtering. |
| THD+N | 0.0001% at 1kHz, 3VRMS output - meets professional audio line-level distortion requirements. |
| Common-mode input range | ±14V at ±15V supplies - allows direct interfacing with ±12V signal sources without level-shifting. |
| Slew rate | 2.2V/μs - supports full-scale 10Vpp output at ≤35kHz without slewing-induced distortion. |
| Supply current (dual) | 5.6mA typical at ±15V - enables low-power operation in multi-channel audio systems with thermal margin. |
| Input offset voltage | 6mV typical - ensures ≤10mV DC error in non-inverting gain-of-10 stages at room temperature. |
Pinout & Package
RC4558IP uses an 8-pin plastic dual in-line package (PDIP) measuring 9.81mm × 9.43mm, with through-hole mounting and standard 0.3-inch row spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Amplifier 1 output | Low-impedance buffered output node; drives 2kΩ loads to ±13.8V with <0.0001% THD+N. |
| 2 | Amplifier 1 inverting input | Differential input terminal; accepts feedback networks for precise gain control in inverting configurations. |
| 3 | Amplifier 1 noninverting input | High-impedance input node; supports voltage-follower use with ±14V common-mode range. |
| 4 | Negative supply (VCC−) | Reference return for dual-supply operation; must be decoupled with 0.1µF ceramic capacitor near pin. |
| 5 | Amplifier 2 noninverting input | Independent second amplifier input; electrically isolated from Channel 1 with >120dB crosstalk attenuation. |
| 6 | Amplifier 2 inverting input | Second differential input; supports independent gain-setting resistors without interaction with Channel 1. |
| 7 | Amplifier 2 output | Matched output stage; exhibits identical slew rate and noise performance as Pin 1 for stereo applications. |
| 8 | Positive supply (VCC+) | Power rail for dual-supply operation; rated for ±5V to ±15V; absolute max ±18V. |
Key Features
| Feature | Design Value |

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 |
|---|---|---|---|
| NE5532AP | Higher 10MHz GBW, 3.5V/μs slew rate, lower 5nV/√Hz noise, but requires ±15V min supply and draws 8mA. | Better suited for high-fidelity headphone amps; less ideal for cost-sensitive AV receivers due to higher power and price. | Select NE5532AP only when >5MHz bandwidth or sub-5nV/√Hz noise is mandatory; RC4558IP offers better cost/performance balance for line-level audio. |
| LM833N | Identical 4MHz GBW and 2.2V/μs slew rate, but higher 8nV/√Hz noise and 0.0002% THD+N at 1kHz. | Acceptable for consumer audio where 0.0002% THD+N is sufficient; lacks RC4558IP's ±14V common-mode range. | Choose LM833N for legacy designs or inventory reuse; RC4558IP delivers superior common-mode tolerance and lower distortion for new audio layouts. |
Compared with NE5532AP and LM833N, RC4558IP provides the optimal trade-off of low THD+N (0.0001%), wide common-mode range (±14V), and moderate power (5.6mA), making it the preferred choice for cost-sensitive, thermally constrained stereo line-level applications requiring proven reliability.

FAQ
What is the maximum supply voltage for RC4558IP?
The RC4558IP has an absolute maximum supply voltage rating of ±18V. For reliable operation, TI specifies recommended conditions of ±5V to ±15V. Exceeding ±18V risks permanent damage to the internal circuitry, and operation above ±15V may degrade THD+N and output swing performance beyond datasheet limits. Always use 0.1µF ceramic bypass capacitors at VCC+ and VCC− pins when operating RC4558IP.
Does RC4558IP require external compensation components?
No, RC4558IP does not require external frequency compensation components. It is internally compensated for unity-gain stability across its full operating temperature range (0°C to 70°C). This eliminates the need for external capacitors or resistors in standard non-inverting or inverting amplifier configurations, reducing bill-of-materials count and PCB area in audio preamp and buffer designs using RC4558IP.
What is the typical input offset voltage of RC4558IP?
The typical input offset voltage of RC4558IP is 6mV at 25°C, with a maximum of 7.5mV across the full 0°C to 70°C operating range. This value directly impacts DC accuracy in precision gain stages - for example, in a non-inverting amplifier with gain = 10, a 6mV offset produces ~60mV output error. RC4558IP's offset drift is specified in Figure 5-19, showing <500µV variation over temperature.
Can RC4558IP operate from a single supply?
Yes, RC4558IP can operate from a single supply by referencing VCC− to ground and applying a mid-rail bias (e.g., VCC+/2) to both noninverting inputs. However, its common-mode input range extends only to within ~3V of each rail, so input signals must be centered accordingly. The device's lack of rail-to-rail input/output limits single-supply headroom; for full 0–VCC swing, consider rail-to-rail alternatives - RC4558IP is optimized for ±5V to ±15V dual-supply audio use.
How does RC4558IP compare to RC4558P in terms of specifications?
RC4558IP and RC4558P share identical electrical specifications, pinout, and thermal characteristics. The "I" suffix denotes the industrial temperature grade (–40°C to +85°C), while the standard RC4558P is rated for 0°C to +70°C. Both use the same PDIP-8 package (P), and all key parameters - including 4MHz GBW, 6.5nV/√Hz noise, and 0.0001% THD+N - are identical at 25°C. RC4558IP is selected when extended temperature operation is required in demanding environments.
