Product details
Overview
RC4580IDRG4 from Texas Instruments is a dual audio operational amplifier optimized for high-fidelity preamplification, active filtering, and headphone drive applications. It delivers 12MHz gain-bandwidth product, 5V/μs slew rate, 0.8μVrms input noise voltage, 0.0005% total harmonic distortion at 1kHz, and operates from ±2V to ±16V supply rails.
For engineers reviewing the RC4580IDRG4 datasheet, RC4580IDRG4 pinout, RC4580IDRG4 application, or RC4580IDRG4 equivalent, key selection criteria include low-noise audio signal conditioning, rail-compatible dual-supply operation, and compatibility with legacy audio op-amp footprints including NE5532 and NJM4580.
Technical Context
The RC4580IDRG4 integrates two matched, internally compensated op-amps in a single SOIC-8 package. Its architecture supports both dual-supply (±2V to ±16V) and single-supply operation with common-mode input range extending to ±13.5V and output swing up to ±13.5V into 2kΩ loads.
It features unity-gain-stable design with 110dB CMRR and PSRR, 90–110dB open-loop gain, and 6–9mA total quiescent current across temperature. Input bias current remains below 500nA, enabling high-impedance sensor and tone-control interface use without significant DC error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain bandwidth product | 12MHz - enables stable closed-loop operation up to ~1MHz at gain ≥12, suitable for wideband audio and active filter design |
| Slew rate | 5V/μs - supports full-swing 20kHz sine output without slewing distortion at >10Vpp, critical for transient-rich audio signals |
| Input noise voltage | 0.8μVrms (RIAA-weighted, 30kHz LPF) - ensures negligible contribution to system noise floor in microphone and phono preamp stages |
| Total harmonic distortion | 0.0005% at 1kHz, 5Vpp, 2kΩ load - meets high-end audio line-level and headphone driver requirements |
| Supply voltage range | ±2V to ±16V - supports battery-powered portable audio (±3V) and professional gear (±15V), with absolute max ±18V |
| Output current | ±50mA - drives 32Ω headphones directly with <0.1% THD at 100mW, eliminating need for external buffer stages |
| Common-mode rejection | 110dB - rejects power supply ripple and ground noise in differential-input configurations and balanced interfaces |
Pinout & Package
RC4580IDRG4 is supplied in an 8-pin SOIC (D) package measuring 3.9mm × 4.9mm, RoHS-compliant with NiPdAu lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OUT) | Output | Amplifier A output - capable of ±50mA drive into 32Ω; requires local 0.1μF bypass to VCC+ for stability |
| 2 (1IN–) | Inverting input | Differential input node for Amplifier A - high-impedance (500nA max IB), sensitive to PCB layout parasitics |
| 3 (1IN+) | Noninverting input | Reference input for Amplifier A - common-mode range extends to ±13.5V, enabling rail-to-rail signal handling |
| 4 (VCC–) | Negative supply | Ground reference for dual-supply operation or negative rail in split-supply systems; must be decoupled |
| 5 (2IN+) | Noninverting input | Reference input for Amplifier B - electrically isolated from Amplifier A; shares same VCC+/VCC– rails |
| 6 (2IN–) | Inverting input | Differential input node for Amplifier B - matched to Pin 2 for dual-channel symmetry in stereo applications |
| 7 (2OUT) | Output | Amplifier B output - identical drive capability and noise performance as Pin 1; supports independent channel use |
| 8 (VCC+) | Positive supply | Power rail for both amplifiers - requires dedicated 0.1μF ceramic capacitor placed ≤2mm from pin per TI layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Audio-optimized architecture | Low 0.0005% THD+N and 0.8μVrms noise enable transparent signal path in phono, mic, and line preamps |
| Drop-in replacement capability | Pins 1–8 match LM833, NE5532, NJM4558/4560 families - allows direct substitution without PCB revision |
| Wide supply flexibility | Operates from ±2V to ±16V - supports 5V single-supply (with level-shifting) and ±15V professional audio rails |
| High-output-current drive | ±50mA per channel - directly powers 32Ω headphones at 100mW with <0.1% THD, eliminating discrete buffers |
| Thermal robustness | RθJA = 109°C/W in SOIC-8 - sustains continuous operation at 125°C ambient when properly heatsinked on 2-layer board |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual audio operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Higher 38V/μs slew rate but 5μVrms noise; wider ±20V abs max rating; higher 14mA ICC | Better for ultrasonic-capable active filters; less optimal for ultra-low-noise phono stages | Select NE5532DR when slew-limited distortion dominates; avoid where input-referred noise <1μVrms is mandatory |
| NJM4580D | Identical pinout and electrical specs; lower 105dB CMRR; not qualified for industrial temp range (–40°C to 125°C) | Limited to commercial-grade audio equipment; unsuitable for automotive or industrial environments | Choose NJM4580D only for cost-sensitive consumer audio; RC4580IDRG4 preferred for reliability-critical designs |
Compared with NE5532DR and NJM4580D, RC4580IDRG4 uniquely balances ultra-low noise (0.8μVrms), high slew (5V/μs), industrial temperature range, and drop-in compatibility-making it optimal for next-generation audio equipment requiring both fidelity and robustness.

FAQ
What is the maximum operating supply voltage for RC4580IDRG4?
The RC4580IDRG4 has an absolute maximum supply voltage rating of ±18V, but its recommended operating range is ±2V to ±16V. Operation beyond ±16V risks exceeding thermal limits and degrading long-term reliability. The RC4580IDRG4 achieves optimal THD and noise performance within ±15V, and remains fully functional down to ±2V for low-power portable audio applications.
Is RC4580IDRG4 pin-compatible with NE5532?
Yes, RC4580IDRG4 is pin- and function-compatible with NE5532 in SOIC-8 packaging. Both share identical pin assignments (1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+) and similar electrical behavior, enabling direct substitution in existing layouts. However, RC4580IDRG4 offers lower noise (0.8μVrms vs 5μVrms) and lower THD (0.0005% vs 0.0008%), making it preferable for high-fidelity upgrades.
Can RC4580IDRG4 drive 32Ω headphones directly?
Yes, RC4580IDRG4 can drive 32Ω headphones directly with <0.1% THD at 100mW output power. Its ±50mA output current capability, combined with ±13.5V output swing into 2kΩ and thermal protection, enables robust headphone amplification without external buffers. For best results, use ±5V supplies and implement local 0.1μF bypassing per TI layout guidelines.
What is the input common-mode voltage range of RC4580IDRG4?
The RC4580IDRG4 supports an input common-mode voltage range of ±13.5V under recommended operating conditions (VCC± = ±15V). This exceeds rail-to-rail input capability and allows full utilization of the ±15V supply in professional audio circuits. At lower supplies (e.g., ±5V), the common-mode range scales proportionally while maintaining >12V span, ensuring compatibility with DC-coupled tone control and active filter topologies.
Does RC4580IDRG4 require external compensation components?
No, RC4580IDRG4 is internally compensated and unity-gain stable. It does not require external capacitors or resistors for frequency compensation. Its 12MHz gain-bandwidth product and 5V/μs slew rate are guaranteed across –40°C to 125°C without added components. External feedback networks (e.g., RF, RG) are needed only for setting closed-loop gain and configuring filter responses per application requirements.
