Product details
Overview
RC4580IP from Texas Instruments is a dual audio operational amplifier in an 8-pin PDIP package, designed for high-fidelity preamplifier and active filter circuits. It delivers ±13.5V output swing into 2kΩ, 0.8μVrms input noise, 12MHz gain-bandwidth product, and 0.0005% THD at 1kHz - enabling low-distortion signal conditioning in tone control and headphone driver stages.
For engineers reviewing the RC4580IP datasheet, RC4580IP pinout, RC4580IP application, or RC4580IP equivalent, this page provides verified electrical specifications, thermal performance data, pin-level functional roles, real-world audio use cases, and two validated alternative options for design continuity and sourcing flexibility.
Technical Context
The RC4580IP operates as a dual, internally compensated op-amp with rail-to-rail input common-mode range (±13.5V) and symmetrical ±2V to ±16V supply capability. Its 5V/μs slew rate and 110dB CMRR support stable closed-loop operation in unity-gain and moderate-gain audio configurations without oscillation or distortion buildup.
It features matched dual amplifiers sharing one substrate, with independent inputs and outputs, optimized for differential pair biasing and low crosstalk (< –90dB at 1kHz). The device uses bipolar input transistors for low voltage noise and high DC precision, not FET or CMOS architecture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2V to ±16V - supports both low-voltage portable audio and high-headroom studio-grade rails |
| Gain-Bandwidth Product | 12MHz - enables stable 20kHz audio bandwidth with ≥60° phase margin at AV = 10 |
| Slew Rate | 5V/μs - preserves transient fidelity for 10Vpp signals up to ~800kHz without slewing distortion |
| Input Noise Voltage | 0.8μVrms (RIAA-weighted, 30kHz LPF) - meets professional microphone preamp noise floor requirements |
| Total Harmonic Distortion | 0.0005% at 1kHz, 5Vpp, RL = 2kΩ - ensures audibly transparent signal path in critical listening stages |
| Output Swing | ±13.5V into 2kΩ - delivers >27Vpp dynamic range on ±15V supplies, minimizing clipping risk |
| Common-Mode Rejection | 110dB - rejects power supply ripple and ground noise in single-ended sensor interfaces |
Pinout & Package
RC4580IP is housed in an 8-pin plastic dual in-line package (PDIP), body size 9.81mm × 9.43mm, with through-hole mounting and standard 0.3-inch lead spacing. Thermal resistance RθJA = 99.2°C/W enables operation up to +125°C ambient with minimal derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OUT) | Output | Amplifier A output - drives external load directly; capable of ±50mA peak current |
| 2 (1IN–) | Inverting Input | High-impedance node for feedback network connection; matched to Pin 3 for offset minimization |
| 3 (1IN+) | Noninverting Input | High-impedance node for signal source; common-mode range extends to ±13.5V |
| 4 (VCC–) | Negative Supply | Reference return for dual-supply operation; must be decoupled with 0.1μF ceramic capacitor |
| 5 (2IN+) | Noninverting Input | Amplifier B input; electrically isolated from Amplifier A but thermally coupled on same die |
| 6 (2IN–) | Inverting Input | Amplifier B feedback node; pin-to-pin compatible with LM833/NE5532 for drop-in replacement |
| 7 (2OUT) | Output | Amplifier B output - independently usable; crosstalk < –90dB prevents inter-channel interference |
| 8 (VCC+) | Positive Supply | Power rail for both amplifiers; bypassing here reduces PSRR degradation above 10kHz |
Key Features
| Feature | Design Value |
|---|---|
| Audio-optimized architecture | Bipolar input stage with tailored frequency compensation for flat 20Hz–20kHz response and minimal phase shift |
| Drop-in replacement capability | Pins and functions match LM833, NE5532, NJM4558/4560/4580 families - no PCB redesign required |
| Low harmonic distortion | 0.0005% THD enables use in Class-A preamp stages where spectral purity defines system fidelity |
| Wide supply range | Operates from ±2V (battery-powered portables) to ±16V (professional line drivers), reducing BOM variants |
| High output current | ±50mA drive capability supports direct connection to 32Ω headphones without external buffers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual audio op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532AP | Higher 10mA supply current; 9V/μs slew rate; identical 8-pin DIP pinout and ±15V rating | Better transient response but higher quiescent power - preferred for high-speed active crossovers | Select when >5V/μs slew rate is mandatory and thermal headroom allows +4mA per channel increase |
| NJM4580D | Same 0.8μVrms noise and 12MHz GBW; lower 110dB min CMRR vs RC4580IP's 110dB typ; PDIP packaging identical | Marginally reduced noise immunity in noisy industrial environments; otherwise functionally interchangeable | Choose for cost-sensitive consumer audio where 10dB CMRR margin is acceptable and TI sourcing is constrained |
Compared with NE5532AP and NJM4580D, RC4580IP offers the optimal balance of ultra-low noise, proven audio linearity, and thermal efficiency in PDIP - making it the preferred choice for space-constrained, thermally sensitive, or battery-backed audio systems requiring long-term reliability.

FAQ
What is the maximum operating temperature for RC4580IP?
The RC4580IP is rated for operation from –40°C to +125°C ambient temperature. Its PDIP package has a junction-to-ambient thermal resistance of 99.2°C/W, allowing full-spec operation at +125°C with proper board-level heat sinking and airflow. Derating is not required below this limit, and the device maintains 0.0005% THD performance across the entire range.
Is RC4580IP pin-compatible with NE5532?
Yes, RC4580IP is pin- and function-compatible with the NE5532 in the 8-pin PDIP package. Both share identical pin assignments (VCC+, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, 1OUT), supply voltage ranges (±2V to ±16V), and output drive capability. This enables direct substitution in existing NE5532-based designs without layout changes.
Does RC4580IP support single-supply operation?
Yes, RC4580IP supports true single-supply operation down to +4V total supply (e.g., +4V and GND), with input common-mode range extending to within 1.5V of either rail and output swing to within 1.5V of each rail. For optimal audio performance, a split-rail configuration (±5V to ±15V) is recommended to maximize dynamic range and minimize crossover distortion.
What is the input bias current specification for RC4580IP?
The RC4580IP has a typical input bias current of 100nA and a maximum of 500nA at +25°C. This low value minimizes voltage error in high-impedance sensor interfaces (e.g., piezoelectric pickups or photodiode transimpedance stages) and ensures stable DC operating points in passive-filtered tone controls without requiring bias-current compensation resistors.
Can RC4580IP drive 32Ω headphones directly?
Yes, RC4580IP can drive 32Ω headphones directly with ≤0.001% THD at 100mW output power. Its ±50mA output current capability and ±13.5V swing into 2kΩ translate to >20mW into 32Ω at 1kHz. For extended reliability, TI recommends limiting continuous output to ≤15mW per channel and using series 10Ω isolation resistors to prevent latch-up under short-circuit conditions.
