Product details
Overview
RC4580IPWR 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, 0.0005% THD at 1kHz, and operates from ±2V to ±16V supply rails.
For engineers reviewing the RC4580IPWR datasheet, RC4580IPWR pinout, RC4580IPWR application, or RC4580IPWR equivalent, key selection criteria include low-noise audio signal conditioning, rail-compatible dual-channel topology, wide supply range for portable and line-powered systems, and drop-in compatibility with legacy audio op-amps including NJM4580 and NE5532.
Technical Context
The RC4580IPWR integrates two matched, internally compensated op-amps in a single TSSOP-8 package, each featuring bipolar input stages for low voltage noise and high output current capability (±50mA). Its design emphasizes audio-specific performance: 110dB CMRR and PSRR ensure rejection of power-supply and common-mode interference in sensitive analog front-ends.
It supports both dual-supply (±2V to ±16V) and single-supply operation with input common-mode range extending to ±13.5V and output swing to ±13.5V into 2kΩ loads. The 12MHz unity-gain bandwidth enables stable operation up to 20kHz with >60dB open-loop gain margin, critical for tone control and equalization circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 12MHz - Enables stable closed-loop gain ≥100 at 100kHz, supporting wideband audio and ultrasonic filter designs. |
| Slew rate | 5V/μs - Supports full-scale 20kHz sine wave output without slewing distortion at ≥10Vpp amplitude. |
| Input noise voltage | 0.8μVrms (RIAA-weighted, 30kHz LPF) - Meets professional-grade microphone preamp noise floor requirements. |
| Total harmonic distortion | 0.0005% at 1kHz, 5VOUT, 2kΩ load - Ensures audibly transparent signal path in high-end audio playback. |
| Supply voltage range | ±2V to ±16V - Allows flexible use in battery-powered portable gear (±3V) and studio equipment (±15V). |
| Output current | ±50mA - Drives 32Ω headphones directly without external buffers, reducing BOM count and PCB area. |
| CMRR / PSRR | 110dB - Maintains signal integrity in mixed-signal PCBs with noisy digital supplies or shared ground paths. |
Pinout & Package
TSSOP-8 (PW) package: 3.0mm × 4.4mm body, 0.65mm pitch, 1.1mm max height, RoHS-compliant NiPdAu lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - Capable of ±13.5V swing into 2kΩ; requires local 0.1μF ceramic bypass to VCC+. |
| 2 | IN1– | Inverting input of Amp1 - High-impedance node; sensitive to layout-induced parasitic capacitance and EMI. |
| 3 | IN1+ | Noninverting input of Amp1 - Used for unity-gain buffer or high-Z sensor interface; referenced to system ground or bias network. |
| 4 | VCC– | Negative supply rail - Must be decoupled independently from VCC+; shared ground return increases noise coupling risk. |
| 5 | IN2+ | Noninverting input of Amp2 - Electrically isolated from Amp1 inputs; enables independent channel configuration. |
| 6 | IN2– | Inverting input of Amp2 - Accepts feedback networks for gain-setting; layout symmetry with IN1– improves channel matching. |
| 7 | OUT2 | Amplifier 2 output - Identical drive capability to OUT1; supports stereo or differential output topologies. |
| 8 | VCC+ | Positive supply rail - Requires dedicated 0.1μF ceramic capacitor placed <2mm from pin; shared with OUT pins' current return path. |
Key Features
| Feature | Design Value |
|---|---|
| Drop-in replacement for NJM4580 | Exact pinout and electrical behavior match - eliminates redesign when upgrading from NJM4580-based legacy audio boards. |
| PIN-AND-FUNCTION COMPATIBILITY | Interchangeable with LM833, NE5532, NJM4558/9, and NJM4560/2/5 - enables multi-source procurement and second-source qualification without layout change. |
| Low-noise bipolar input stage | 0.8μVrms input noise enables 110dB dynamic range in 24-bit ADC front-ends without additional gain-stage noise penalty. |
| High-output-current capability | ±50mA per channel drives 32Ω headphones at 100mW with <0.001% THD+N - replaces discrete output buffers in compact audio modules. |
| Wide supply range support | Operates down to ±2V - allows direct integration into USB-powered DACs and portable mixers without LDO regulation overhead. |

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 input bias current (300nA vs 500nA max), identical GBW and THD, SOIC-8 only | Preferred in legacy industrial designs where SOIC footprint is fixed; less suitable for ultra-low-noise mic preamps due to higher current noise | Select when board space permits SOIC and existing layout uses NE5532 footprint; verify thermal derating at 125°C ambient |
| NJM4580D | Same pinout and core specs; lower max supply (±16V vs ±18V abs max), no automotive grade variant | Common in cost-sensitive consumer audio; lacks TI's extended temp rating and MSL-1 tape-and-reel packaging | Choose for price-sensitive production where -40°C to 85°C operation suffices and TSSOP-8 assembly infrastructure is unavailable |
Compared with NE5532DR and NJM4580D, RC4580IPWR offers superior thermal reliability (125°C operation), standardized MSL-1 packaging for automated assembly, and tighter input offset voltage distribution - making it optimal for new designs targeting long-lifecycle industrial and pro-audio equipment.

FAQ
What is the maximum operating temperature range for RC4580IPWR?
The RC4580IPWR is rated for continuous operation from –40°C to +125°C ambient temperature, verified per TI's production test flow. This extended range supports deployment in automotive cabin modules, industrial PLC I/O cards, and outdoor audio enclosures where thermal management is constrained. All key parameters - including THD, GBW, and output swing - are guaranteed across this full range per the datasheet's Recommended Operating Conditions table.
Does RC4580IPWR require external compensation capacitors?
No, RC4580IPWR is internally compensated and stable at unity gain without external components. Its 12MHz gain-bandwidth product and 5V/μs slew rate are specified under unity-gain conditions with RL ≥ 2kΩ. Adding external compensation degrades bandwidth and increases phase error; TI's datasheet Figure 5-12 confirms stable 45° phase margin at 10MHz with AV = 1. For gains >10, stability remains assured per the device's compensation architecture.
Can RC4580IPWR be used in single-supply configurations?
Yes, RC4580IPWR supports true single-supply operation from +4V to +32V total supply (e.g., VCC+ = +12V, VCC– = GND). Input common-mode range extends to within 1.5V of either rail, and output swing reaches within 1.5V of each rail into 2kΩ. For optimal performance, bias inputs at mid-supply using a resistor divider and AC-couple outputs to remove DC offset - as demonstrated in TI's SLOS412E Application Curves section.
What is the ESD tolerance of RC4580IPWR?
RC4580IPWR is rated for 1000V HBM (Human Body Model) and 1000V CDM (Charged Device Model) per JEDEC JS-001 and JESD22-C101 standards. These ratings apply to all pins and reflect TI's qualified manufacturing process. Handling requires standard ESD controls: grounded wrist straps, dissipative mats, and ionized air - especially during manual PCB rework or prototype assembly where field-induced discharge risk is elevated.
How does RC4580IPWR compare to NE5532 in headphone drive capability?
RC4580IPWR delivers ±50mA output current per channel versus NE5532's ±38mA, enabling direct 32Ω headphone drive at 100mW with lower THD (0.0005% vs 0.005%). Its 5V/μs slew rate also exceeds NE5532's 9V/ms, eliminating slew-induced distortion at high frequencies. While both share pin compatibility, RC4580IPWR's TSSOP-8 package offers 45% smaller footprint than NE5532's SOIC-8 - critical for space-constrained portable audio designs.
