Product details
Overview
RC4580QDRQ1 from Texas Instruments is a dual automotive-grade operational amplifier optimized for audio signal conditioning, delivering 0.8 μVrms input noise, 12 MHz gain-bandwidth, and 0.0005% THD at 1 kHz - enabling high-fidelity preamplification in vehicle infotainment head units.
For engineers reviewing the RC4580QDRQ1 datasheet, RC4580QDRQ1 pinout, RC4580QDRQ1 application, or RC4580QDRQ1 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification (–40°C to 125°C), ±2 V to ±18 V supply flexibility, and drop-in compatibility with legacy audio op-amps in space-constrained SOIC-8 layouts.
Technical Context
The RC4580QDRQ1 integrates two matched high-slew-rate amplifiers (5 V/μs) in a single SOIC-8 package, each featuring rail-to-rail output swing (±12 V into 2 kΩ) and wide common-mode input range (±13.5 V). Its internal compensation ensures stable unity-gain operation across automotive temperature extremes.
Designed specifically for analog audio paths, it employs low-noise bipolar input stages and achieves 110 dB CMRR and PSRR - critical for rejecting engine noise coupling and maintaining SNR in 12 V battery-supplied systems without external filtering overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±2 V to ±18 V - supports direct connection to automotive 12 V battery rails with headroom for transients and ripple. |
| Input Noise Voltage | 0.8 μVrms (TYP) - enables >110 dB SNR in microphone preamp stages without additional noise-shaping circuitry. |
| Gain-Bandwidth Product | 12 MHz (TYP) - sustains flat frequency response up to 20 kHz with ≥20 dB gain, suitable for RIAA equalization and active crossover filters. |
| Total Harmonic Distortion | 0.0005% (TYP) at 1 kHz - meets THX-certified audio fidelity requirements for OEM cabin speaker drivers. |
| Slew Rate | 5 V/μs - prevents slew-induced distortion on fast transient signals like drum hits or digital audio bursts. |
| Common-Mode Rejection | 110 dB (TYP) - rejects coupled alternator noise and CAN bus switching interference in shared-chassis ground systems. |
| Ambient Temperature Range | –40°C to 125°C - qualified per AEC-Q100 Grade 1 for under-hood or dashboard-mounted audio modules. |
Pinout & Package
RC4580QDRQ1 uses an 8-pin SOIC (D) package with 1.75 mm max height, JEDEC MS-012 compliant footprint, and NIPDAU lead finish rated MSL Level-1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | Accepts feedback network for closed-loop gain configuration; referenced to internal bias point. |
| 2 | Non-Inverting Input (Amplifier A) | High-impedance node for sensor or line-level signal injection; common-mode range extends to ±13.5 V. |
| 3 | Output (Amplifier A) | Capable of ±50 mA short-circuit current; drives 32 Ω headphones directly without external buffers. |
| 4 | VCC– | Negative supply rail; must be decoupled locally with ≥100 nF ceramic capacitor to suppress low-frequency ripple. |
| 5 | Non-Inverting Input (Amplifier B) | Independent channel input; electrically isolated from Channel A to prevent crosstalk below –90 dB at 1 kHz. |
| 6 | Inverting Input (Amplifier B) | Supports standard active filter topologies (e.g., Sallen-Key, multiple-feedback) with stable phase margin. |
| 7 | Output (Amplifier B) | Delivers identical AC performance to Pin 3; enables stereo preamp or differential driver configurations. |
| 8 | VCC+ | Positive supply rail; accepts up to ±18 V; internal ESD protection clamps at ±15 V per input. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 certified with H2 (2 kV HBM) and C3B (750 V CDM) ESD ratings - validated for 15-year field life in vibration-prone environments. |
| Low-noise architecture | 0.8 μVrms input-referred noise at 30 kHz bandwidth - eliminates need for external noise-filtering stages in phono preamps. |
| Drop-in replacement capability | Pins 1–8 match LM833, NE5532, and NJM4558 - allows legacy board reuse without layout changes or firmware updates. |
| High-output drive strength | ±50 mA output current per channel - directly interfaces with 16 Ω speaker loads or capacitive touch-sensing circuits without external drivers. |
| Wide supply tolerance | Operates from ±2 V to ±18 V - accommodates both low-voltage microcontroller I/O domains and high-headroom analog signal chains. |

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 |
|---|---|---|---|
| LM833N | Same SOIC-8 pinout; 4.5 MHz GBW, 2.5 V/μs slew rate, higher 2.5 μVrms noise. | Lacks AEC-Q100 qualification; not rated for >105°C ambient or automotive ESD stress. | Select when cost sensitivity outweighs thermal/ESD robustness; requires derating above 85°C ambient. |
| NE5532AP | Identical pinout; 10 MHz GBW, 9 V/μs slew rate, 5 μVrms noise, no automotive qualification. | Higher power consumption (16 mA vs. 9 mA); unsuitable for thermally constrained modules near HVAC ducts. | Prefer for studio-grade bench equipment where noise floor is secondary to slew rate; avoid in under-dash mounting locations. |
Compared with LM833N and NE5532AP, RC4580QDRQ1 delivers superior noise performance and guaranteed automotive reliability at identical SOIC-8 footprint - making it the only option qualified for direct integration into OEM infotainment ECUs without additional qualification testing.

FAQ
What automotive qualification level does RC4580QDRQ1 meet?
RC4580QDRQ1 is AEC-Q100 qualified at Grade 1, supporting ambient operating temperatures from –40°C to 125°C. It also meets H2-level human-body model ESD (2 kV) and C3B-level charged-device model ESD (750 V), ensuring robustness against electrostatic discharge in vehicle assembly and service environments. This qualification applies specifically to the RC4580QDRQ1 part number in SOIC-8 packaging.
Is RC4580QDRQ1 pin-compatible with NE5532 or LM833?
Yes, RC4580QDRQ1 is pin and function compatible with LM833, NE5532, NJM4558/9, and NJM4560/2/5 per TI's official documentation. All share identical SOIC-8 pin assignments: Pin 1 (Inv A), Pin 2 (Non-Inv A), Pin 3 (Out A), Pin 4 (V–), Pin 5 (Non-Inv B), Pin 6 (Inv B), Pin 7 (Out B), Pin 8 (V+). No PCB modifications are required for substitution in existing designs using those legacy parts.
What is the maximum output current capability of RC4580QDRQ1?
RC4580QDRQ1 delivers ±50 mA of continuous output current per amplifier channel, as specified in its Absolute Maximum Ratings table. This enables direct driving of 32 Ω headphones or low-impedance active filter loads without external buffer stages. The device maintains 0.0005% THD at 5 V output into 2 kΩ, confirming linear operation within this current range under typical audio conditions.
Does RC4580QDRQ1 support single-supply operation?
RC4580QDRQ1 is designed for dual-supply operation (±2 V to ±18 V), but can be used in single-supply configurations with appropriate input biasing. Its input common-mode range extends to ±13.5 V, and output swing reaches ±12 V into 2 kΩ - allowing use with a 5 V or 12 V rail if the input signal is DC-shifted to mid-rail via resistive divider and coupling capacitors. Full rail-to-rail output is not supported.
How does RC4580QDRQ1's noise performance compare to standard audio op-amps?
RC4580QDRQ1 achieves 0.8 μVrms input-referred noise (typical) over a 30 kHz bandwidth with RIAA weighting, significantly lower than LM833 (2.5 μVrms) and NE5532 (5 μVrms). This 3–6× noise reduction enables higher gain stages in microphone preamplifiers without degrading system SNR, especially critical in quiet cabin environments where background noise floor must remain below 20 dBA.
