Product details
Overview
RC4580ID from Texas Instruments is a dual audio operational amplifier optimized for tone control, preamplification, and headphone drive in ±2V to ±18V supply systems. It delivers 12MHz gain-bandwidth product, 0.8μVrms input noise, 5V/μs slew rate, 0.0005% THD at 1kHz, and ±13.5V output swing into 2kΩ - enabling high-fidelity analog signal conditioning in compact audio front-ends.
For engineers reviewing the RC4580ID datasheet, RC4580ID pinout, RC4580ID application, or RC4580ID equivalent, key selection criteria include low-noise audio performance, dual-channel symmetry, SOIC-8 compatibility with legacy 4580-family layouts, and operation across industrial temperature (–40°C to 125°C) without derating.
Technical Context
The RC4580ID implements two matched, internally compensated op-amps in a single SOIC-8 package, each featuring rail-to-rail input common-mode range (±13.5V) and high open-loop gain (110dB). Its architecture supports both dual-supply (±2V to ±16V) and single-supply configurations, with CMRR and PSRR both rated at 110dB over temperature.
Designed specifically for audio signal chains, the device uses a low-noise bipolar input stage and high-output-current output stage (±50mA), allowing direct headphone driving without external buffers. Its 12MHz unity-gain bandwidth and 5V/μs slew rate support wideband active filters and line-level signal processing up to ~100kHz with minimal phase distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2V to ±16V operating; ±18V absolute max - supports battery-powered portable audio and industrial ±15V rails |
| Gain-Bandwidth Product | 12MHz - enables stable unity-gain active filters and 20kHz audio amplifiers with >60dB loop gain margin |
| Slew Rate | 5V/μs - preserves transient fidelity for 10Vpp signals up to ~800kHz without slewing-induced distortion |
| Input Noise Voltage | 0.8μVrms (RIAA-weighted, 30kHz LPF) - ensures <100nV/√Hz spectral density for phono-stage and mic-pre applications |
| Total Harmonic Distortion | 0.0005% at 1kHz, 5Vpp, 2kΩ load - meets high-end consumer audio THD+N requirements below –106dB |
| Output Voltage Swing | ±13.5V into 2kΩ - delivers full dynamic range in ±15V systems with <1.5V headroom |
| Input Offset Voltage | 3mV typical - minimizes DC error in DC-coupled tone controls and active crossover networks |
Pinout & Package
RC4580ID is packaged in an 8-pin SOIC (D package), 3.9mm × 4.9mm body size, with standard JEDEC MS-012AC footprint and 1.27mm pitch. The package supports automated assembly and meets IPC/JEDEC J-STD-020 moisture sensitivity Level-1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier A output - drives tone-control networks or active filter feedback paths with ±50mA capability |
| 2 | IN1– | Inverting input of Amp A - accepts feedback resistor for precision gain-setting in inverting configurations |
| 3 | IN1+ | Noninverting input of Amp A - connects to sensor, source, or reference for unity-gain buffering or differential sensing |
| 4 | VCC– | Negative supply rail - must be decoupled with 0.1μF ceramic capacitor placed ≤2mm from pin |
| 5 | IN2+ | Noninverting input of Amp B - enables dual-channel stereo processing or independent signal paths |
| 6 | IN2– | Inverting input of Amp B - used for matched gain stages in balanced line drivers or dual active filters |
| 7 | OUT2 | Amplifier B output - identical performance to OUT1; supports stereo headphone drive or dual-channel instrumentation |
| 8 | VCC+ | Positive supply rail - requires local 0.1μF bypass to ground; shared rail design simplifies power layout |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise audio optimization | 0.8μVrms input noise enables phono preamp use without additional low-noise front-end stages |
| Dual-channel matching | Matched offset, gain, and bandwidth between channels ensures consistent stereo imaging and crosstalk < –90dB |
| High-output current | ±50mA per channel allows direct 32Ω headphone drive at 100mW without external transistors |
| Wide supply flexibility | Operates from ±2V to ±16V - supports single-cell Li-ion (3.3V) to industrial ±15V systems without redesign |
| Drop-in replacement capability | Pins 1–8 match LM833, NE5532, NJM4558/9, and NJM4560/2/5 - enables legacy board reuse |

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 input bias current (300nA vs 500nA max), same 12MHz GBW and 5V/μs slew rate; wider VCC range (±5V to ±20V) | Better suited for high-source-impedance sensor interfaces; less optimal for ultra-low-noise phono stages | Select NE5532DR when sourcing impedance exceeds 10kΩ or supply rails exceed ±16V |
| NJM4580D | Identical pinout and electrical specs; lower production volume and limited industrial temp support (–20°C to 75°C only) | Acceptable for commercial audio gear but not qualified for extended temperature industrial use | Select NJM4580D only for cost-sensitive consumer products with ambient temp < 75°C |
Compared with NE5532DR and NJM4580D, RC4580ID provides guaranteed industrial temperature operation (–40°C to 125°C), tighter input offset voltage (3mV typ vs 5mV typ), and TI's long-term supply commitment - making it preferred for embedded audio in automotive infotainment, medical monitors, and industrial test equipment.

FAQ
What is the maximum operating supply voltage for RC4580ID?
The RC4580ID has an absolute maximum supply voltage rating of ±18V, but its recommended operating range is ±2V to ±16V. Operating beyond ±16V risks exceeding thermal limits and may reduce long-term reliability. The RC4580ID datasheet specifies all electrical characteristics at ±15V, and performance remains stable down to ±2V for low-power portable audio designs.
Is RC4580ID pin-compatible with NE5532 and LM833?
Yes, RC4580ID is pin- and function-compatible with NE5532, LM833, NJM4558/9, and NJM4560/2/5 devices in SOIC-8 packaging. All share identical pin 1–8 assignments: OUT1, IN1–, IN1+, VCC–, IN2+, IN2–, OUT2, VCC+. This allows direct substitution on existing PCBs without layout changes, provided supply decoupling and thermal management meet RC4580ID's specifications.
Does RC4580ID support single-supply operation?
Yes, RC4580ID supports true single-supply operation from +4V to +32V (VCC+ to GND), with input common-mode range extending to within 1.5V of either rail and output swing to within 1.5V of each rail. For single-supply use, bias the noninverting inputs at mid-rail (e.g., VCC/2) using a low-impedance divider, and AC-couple inputs/outputs where DC offset is unacceptable.
What is the thermal resistance (RθJA) of RC4580ID in SOIC-8 package?
The junction-to-ambient thermal resistance (RθJA) of RC4580ID in the SOIC-8 (D) package is 109°C/W under standard JEDEC test conditions (1squared inch 2oz copper). With 2cm² of 2oz copper pour connected to VCC– and VCC+ pins, RθJA can be reduced to ~55°C/W - enabling continuous operation at 9mA supply current up to 125°C ambient without thermal shutdown.
Can RC4580ID drive 32Ω headphones directly?
Yes, RC4580ID can drive 32Ω headphones directly with ≤0.001% THD+N at 100mW output. Each amplifier delivers ±50mA output current and ±13.5V swing into 2kΩ; into 32Ω, it sustains ±1.6V at 50mA with <0.0005% THD at 1kHz. For stereo headphone output, configure both channels in parallel or use one per ear with appropriate DC-blocking capacitors.
