Product details
Overview
RC4580QPWRQ1 from Texas Instruments is a dual automotive-grade operational amplifier optimized for high-fidelity audio signal conditioning. It delivers 12 MHz gain-bandwidth, 0.8 μVrms input noise, 0.0005% THD at 1 kHz, ±2 V to ±18 V supply operation, and AEC-Q100 Grade 1 qualification (–40°C to 125°C), enabling use in automotive preamplifiers and active filters.
For engineers reviewing the RC4580QPWRQ1 datasheet, RC4580QPWRQ1 pinout, RC4580QPWRQ1 application, or RC4580QPWRQ1 equivalent, this device serves as a drop-in replacement for NJM4580 and is pin- and function-compatible with LM833, NE5532, and NJM4558/9 - critical for legacy audio system upgrades and AEC-Q100-compliant design reuse.
Technical Context
The RC4580QPWRQ1 integrates two matched op-amps in a single monolithic die with rail-to-rail output swing capability (±12 V into 2 kΩ) and wide common-mode input range (±13.5 V). Its internal architecture supports low-noise audio amplification without external compensation, maintaining stability at unity gain and up to 20 dB closed-loop gain.
It features HBM ESD rating of 2 kV (Level H2) and CDM rating of 750 V (Level C3B), alongside thermal resistance θJA = 163°C/W in the TSSOP-8 (PW) package - confirming suitability for thermally constrained automotive cabin modules and industrial measurement front-ends operating across full Grade 1 temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±2 V to ±18 V - supports both low-voltage portable audio and high-headroom automotive line-level stages. |
| Gain-Bandwidth Product | 12 MHz (TYP) - enables stable 20× gain at 600 kHz, sufficient for RIAA equalization and ultrasonic filter roll-off. |
| Input Noise Voltage | 0.8 μVrms (TYP, RIAA-weighted) - preserves dynamic range in microphone preamp and phono stage designs. |
| Total Harmonic Distortion | 0.0005% (TYP, 5 VPP, 1 kHz, 2 kΩ load) - meets THD requirements for premium automotive infotainment DAC output buffering. |
| Slew Rate | 5 V/μs (TYP) - ensures faithful reproduction of fast transients in headphone driver and active crossover applications. |
| Common-Mode Rejection | 80–110 dB - rejects engine noise coupling in differential sensor interfaces and balanced line receivers. |
| Ambient Temperature Range | –40°C to 125°C - certified per AEC-Q100 Grade 1 for under-hood and dashboard-mounted electronics. |

| 3 | Output (Channel A) | Capable of ±12 V swing into 2 kΩ; drives capacitive loads ≤100 pF without oscillation. |
| 4 | V– | Negative supply rail connection; must be decoupled locally with ≥0.1 μF ceramic capacitor. |
| 5 | Non-Inverting Input (Channel B) | Independent input for second channel; electrically isolated from Channel A except shared supply rails. |
| 6 | Inverting Input (Channel B) | Supports independent feedback loop; pin-compatible with LM833 and NE5532 for dual-channel routing. |
| 7 | Output (Channel B) | Matches Channel A performance; enables stereo preamp or dual-path active filtering without layout redesign. |
| 8 | V+ | Positive supply rail connection; requires local 0.1 μF ceramic + 10 μF tantalum decoupling for low-THD operation. |

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 |
|---|---|---|---|
| LM833N/NOPB | Higher input bias current (800 nA vs. 500 nA max), same GBW and THD; no AEC-Q100 qualification. | Lacks automotive temperature and reliability validation; suitable only for commercial-grade audio equipment. | Select LM833N/NOPB only for non-automotive prototypes where cost is prioritized over qualification compliance. |
| NE5532AP | Higher noise (5 nV/√Hz vs. 3.5 nV/√Hz typical), identical pinout and gain-bandwidth; not AEC-Q100 qualified. | Not rated for 125°C operation; limited to under-dash or non-critical cabin modules with forced cooling. | Choose NE5532AP only if legacy board reuse mandates exact footprint and no thermal stress testing is required. |

FAQ
What is the maximum operating temperature for RC4580QPWRQ1?
The RC4580QPWRQ1 is qualified per AEC-Q100 Grade 1 with an ambient operating temperature range of –40°C to 125°C. This specification is validated across process corners and lifetime reliability testing, ensuring stable operation in engine bay proximity and unventilated dashboard enclosures. The RC4580QPWRQ1 maintains specified THD, GBW, and output swing within this full range.
Is RC4580QPWRQ1 pin-compatible with NE5532?
Yes, RC4580QPWRQ1 is pin- and function-compatible with NE5532, LM833, NJM4558, and NJM4580, as confirmed in the TI datasheet SLOS707A. All share identical TSSOP-8 (PW) pin assignments: Pin 1 (–IN A), Pin 2 (+IN A), Pin 3 (OUT A), Pin 4 (V–), Pin 5 (+IN B), Pin 6 (–IN B), Pin 7 (OUT B), Pin 8 (V+). No PCB changes are needed for direct substitution of RC4580QPWRQ1 into NE5532-based layouts.
What is the typical input noise voltage of RC4580QPWRQ1?
The RC4580QPWRQ1 delivers a typical input noise voltage of 0.8 μVrms, measured under RIAA weighting with RS ≤ 2.2 kΩ and a 30-kHz low-pass filter. This value reflects integrated broadband noise across the audio band (20 Hz–20 kHz) and enables >110 dB SNR in high-resolution audio signal chains. The RC4580QPWRQ1 achieves this while maintaining 12 MHz GBW and 0.0005% THD - a combination rare among automotive op-amps.
Does RC4580QPWRQ1 require external compensation?
No, RC4580QPWRQ1 is unity-gain stable and does not require external compensation components. Its internal frequency compensation ensures stability for closed-loop gains ≥ 1 V/V across all load conditions up to 100 pF. This simplifies design of active filters, tone controls, and preamplifiers using standard RC networks - a key advantage over decompensated op-amps like OPA1612, where RC4580QPWRQ1 offers plug-and-play usability.
What packaging and reel specifications apply to RC4580QPWRQ1?
RC4580QPWRQ1 is supplied in TSSOP-8 (PW) package with 2000 units per large tape-and-reel (reel diameter 330 mm, width 12.4 mm). The device uses NiPdAu (NIPDAU) lead finish, complies with RoHS, and carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH). Pin 1 orientation follows quadrant Q1 per JEDEC MO-153, and the RC4580QPWRQ1 marking is "R4580Q" on the top surface.
