Product details
Overview
RC4580IDG4 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 RC4580IDG4 datasheet, RC4580IDG4 pinout, RC4580IDG4 application, or RC4580IDG4 equivalent, key selection criteria include low-noise audio signal conditioning, rail-compatible dual-channel topology, thermal performance in VSSOP-8 packages, and compatibility with legacy 4580-family designs requiring minimal layout changes.
Technical Context
The RC4580IDG4 integrates two matched, internally compensated op-amps with independent input stages and shared biasing. Its architecture supports both single-supply (e.g., +15V with ground) and split-supply (±15V) operation, with common-mode input range extending to ±13.5V and output swing reaching ±13.5V into 2kΩ loads.
It features unity-gain-stable design with 110dB CMRR and PSRR, enabling precise DC-coupled audio paths and robust rejection of supply ripple and interference-critical for tone control circuits and industrial measurement front-ends where offset drift and noise floor directly impact dynamic range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain bandwidth product | 12MHz - enables stable unity-gain amplification up to audio frequencies without phase margin loss |
| Slew rate | 5V/μs - supports full-scale 20kHz sine wave output without slewing distortion at ±12V swing |
| Input noise voltage | 0.8μVrms (RIAA-weighted, 30kHz LPF) - ensures negligible contribution to system noise floor in phono preamp stages |
| Total harmonic distortion | 0.0005% at 1kHz, 5VOUT, 2kΩ load - meets Hi-Fi line-level signal integrity requirements |
| Supply voltage range | ±2V to ±16V - allows use in battery-powered portable audio (±3V) and professional rack gear (±15V) |
| Output current | ±50mA - drives 32Ω headphones directly without external buffers |
| Input offset voltage | 3mV typical - minimizes DC error in DC-coupled active filters and instrumentation interfaces |
Pinout & Package
VSSOP-8 (DGK) package: 3.0mm × 3.0mm body, 0.5mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives preamp stage or filter network; capable of ±13.5V swing into 2kΩ |
| 2 | IN1– | Inverting input - accepts feedback network for gain-setting; high impedance (>100kΩ) minimizes loading |
| 3 | IN1+ | Noninverting input - referenced to ground or bias network; common-mode range extends to ±13.5V |
| 4 | VCC– | Negative supply rail - must be decoupled with 0.1μF ceramic capacitor placed ≤2mm from pin |
| 5 | IN2+ | Noninverting input - independent channel; enables stereo or differential signal processing |
| 6 | IN2– | Inverting input - supports identical feedback configuration as Channel 1 for matched gain/phase response |
| 7 | OUT2 | Amplifier 2 output - synchronous with OUT1; supports dual-channel headphone drive or stereo active crossover |
| 8 | VCC+ | Positive supply rail - shares same bypassing requirement as VCC–; enables rail-to-rail output swing symmetry |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise audio optimization | 0.8μVrms input noise enables <100dB SNR in phono preamps without additional gain-stage noise penalty |
| Drop-in replacement capability | Pins 1–8 match LM833, NE5532, NJM4558/9, and NJM4560/2/5 - allows direct substitution in legacy PCBs |
| High-output-current drive | ±50mA per channel sustains 32Ω headphone loads at >1Vrms without clipping or thermal shutdown |
| Wide supply flexibility | Operates from ±2V to ±16V - supports 5V single-supply systems via level-shifting or virtual-ground biasing |
| Thermal robustness | RθJA = 160.5°C/W in VSSOP-8 - maintains <85°C junction rise at 9mA ICC under 25°C ambient |

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 |
|---|---|---|---|
| NE5532DR | Higher 10V/μs slew rate but 5μVrms input noise; wider 20MHz GBW; requires ≥±5V supply | Better transient response in ultrasonic sensor drivers; less suitable for ultra-low-noise phono stages | Select when speed outweighs noise floor; verify PCB layout supports higher bandwidth stability |
| NJM4580D | Identical pinout and electrical specs; lower 100dB CMRR; 10nA max IIB vs RC4580IDG4's 500nA | Cost-optimized for consumer audio; reduced rejection of power supply ripple in sensitive measurement | Acceptable for non-critical stereo preamps; avoid in DC-coupled industrial signal chains |
Compared with NE5532DR and NJM4580D, RC4580IDG4 offers the optimal balance of low noise (0.8μVrms), high GBW (12MHz), and wide supply range (±2V to ±16V) for dual-channel audio signal chains where fidelity, flexibility, and drop-in compatibility are jointly required.

FAQ
What is the maximum operating supply voltage for RC4580IDG4?
The RC4580IDG4 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, even if within absolute ratings. For designs targeting ±15V rails, the RC4580IDG4 delivers full specified performance including ±13.5V output swing and 0.0005% THD.
Is RC4580IDG4 pin-compatible with NE5532 and LM833?
Yes, RC4580IDG4 is pin- and function-compatible with NE5532, LM833, NJM4558/9, and NJM4560/2/5 devices in SOIC-8, TSSOP-8, VSSOP-8, and SOT-23-8 packages. This allows direct PCB replacement without layout modification. However, note that RC4580IDG4's VSSOP-8 (DGK) footprint differs mechanically from SOIC-8, so physical interchangeability requires matching package types.
Does RC4580IDG4 support single-supply operation?
Yes, RC4580IDG4 supports single-supply operation by biasing both inputs at mid-rail (e.g., VCC/2) using resistive dividers or dedicated reference ICs. Its input common-mode range extends to within 1.5V of either rail, and output swing reaches within 1.5V of each supply-enabling functional 5V or 3.3V single-rail designs for portable audio interfaces and sensor signal conditioners.
What thermal considerations apply to RC4580IDG4 in VSSOP-8 packaging?
RC4580IDG4 in VSSOP-8 (DGK) has RθJA = 160.5°C/W. At 9mA total supply current and 25°C ambient, junction temperature rises ~1.4°C-well within safe limits. For sustained high-output-current operation, ensure the exposed thermal pad is soldered to ≥1cm² copper pour connected to internal ground plane to reduce RθJB from 95.6°C/W to <40°C/W.
How does RC4580IDG4's noise performance compare to NJM4580D in audio applications?
RC4580IDG4 specifies 0.8μVrms input noise (RIAA-weighted), while NJM4580D typically measures 2–3μVrms. This 15–20dB lower noise floor makes RC4580IDG4 preferable in phono preamplifiers and microphone preamps where signal levels are sub-millivolt. Both share identical pinout and gain-bandwidth, but RC4580IDG4's tighter noise spec directly improves system SNR without circuit redesign.
