Product details
Overview
RC4560IDR from Texas Instruments is a dual audio operational amplifier with ±2 V to ±18 V supply range, 5.5 V/µs slew rate, 15 MHz gain-bandwidth product, 1.2 µVrms input noise, and 0.05% THD at 1 kHz-designed for high-fidelity audio preamplifiers, active filters, and industrial measurement equipment requiring low distortion and wide bandwidth.
For engineers reviewing the RC4560IDR datasheet, RC4560IDR pinout, RC4560IDR application, or RC4560IDR equivalent, this device offers verified performance in ±15 V audio signal chains, supports 400-Ω load driving up to 20 VPP, and delivers stable operation across –40°C to 85°C ambient conditions with SOIC-8 packaging optimized for board-level thermal management.
Technical Context
The RC4560IDR implements a bipolar-input, high-slew-rate op-amp architecture with internal compensation for unity-gain stability. Its differential input stage achieves 86 dB large-signal voltage gain and 90 dB CMRR, enabling precision DC-coupled amplification in instrumentation-grade circuits.
It operates with rail-to-rail output swing capability (±12.5 V into 2 kΩ), maintains 76.5 dB supply-voltage rejection under ±4 V to ±15 V variation, and sustains 5.7 mA total supply current across both amplifiers-supporting low-noise, low-distortion analog signal conditioning without external compensation components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±2 V to ±18 V - enables flexible biasing in single-supply (with level-shifting) or dual-supply audio and test equipment designs |
| Slew Rate | 5.5 V/µs (typ) - supports clean reproduction of fast transients in audio signals up to ~800 kHz full-power bandwidth |
| Gain Bandwidth | 15 MHz (typ) - allows stable closed-loop gain ≥100 at 100 kHz, suitable for active filter stages and wideband instrumentation |
| Input Noise | 1.2 µVrms (typ, RIAA-weighted) - ensures minimal audible hiss in microphone preamps and line-level signal paths |
| THD | 0.05% (typ, 5 VPP, 1 kHz, 2 kΩ) - meets Hi-Fi audio requirements for low-harmonic coloration in consumer and pro-audio gear |
| Input Offset Voltage | 6 mV (max) - permits DC-coupled cascaded gain stages without excessive baseline drift in sensor interfaces |
| Common-Mode Range | ±14 V (min) - accommodates inputs near supply rails in industrial analog front-ends with wide dynamic range |
Pinout & Package
RC4560IDR is housed in an 8-pin SOIC (D) package per JEDEC MS-012 AA, 3.91 mm body width, 1.75 mm max height, with standard gull-wing lead form and moisture sensitivity level 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplifier A output - drives loads up to ±12.5 V at 25 mA, requires local decoupling for stability in high-gain configurations |
| 2 | Inverting Input A | High-impedance node (5 MΩ typ) - sensitive to PCB leakage and stray capacitance; guard ring recommended for <100 nA bias current applications |
| 3 | Non-Inverting Input A | Differential pair input - matched to Pin 2 for common-mode rejection; tied to reference voltage in single-ended configurations |
| 4 | V– | Negative supply rail - must be bypassed with ≥0.1 µF ceramic capacitor within 5 mm of Pin 4 to suppress PSRR degradation |
| 5 | Non-Inverting Input B | Independent input for second amplifier - electrically isolated from Amp A; shares same V–/V+ rails |
| 6 | Inverting Input B | Second amplifier inverting node - identical electrical characteristics to Pin 2; supports dual-channel feedback networks |
| 7 | Output B | Amplifier B output - fully independent of Output A; usable for stereo channels or differential driver pairs |
| 8 | V+ | Positive supply rail - requires symmetric decoupling to V– for optimal THD and noise performance in audio applications |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | Operates from ±2 V to ±18 V - eliminates need for separate voltage regulators in mixed-signal systems with varying rail constraints |
| Low Distortion | 0.05% THD at 1 kHz - preserves harmonic integrity in audio signal paths without post-processing correction |
| High Slew Rate | 5.5 V/µs - prevents slew-induced distortion on transient-rich waveforms like drum hits or square-wave clocks |
| Low Input Noise | 1.2 µVrms - enables direct coupling to low-output sensors (e.g., piezoelectric pickups) without added noise floor penalty |
| Robust Output Drive | ±50 mA short-circuit current - sustains 20 VPP into 400 Ω loads, supporting headphone drivers and active crossover networks |

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 (300 nA vs. 500 nA max), lower slew rate (9 V/µs), identical 15 MHz GBW and 0.05% THD | Preferred in legacy audio consoles where NE5532 footprint compatibility is required; less suitable for ultra-low-noise mic preamps | Select when matching existing NE5532 layouts or needing higher output current (±38 mA vs. ±50 mA) |
| OPA2134PA | FET-input architecture (2 pA IIB), lower noise (8 nV/√Hz vs. 3.5 nV/√Hz), but only 8 MHz GBW and 20 V/µs slew rate | Better for high-impedance sources (e.g., guitar pickups); insufficient bandwidth for >100 kHz active filters | Select for JFET-input advantages in high-Z sensor interfaces, not for wideband audio or fast transient response |
Compared with NE5532DR and OPA2134PA, RC4560IDR provides superior slew rate and output drive for demanding audio and instrumentation tasks while maintaining industry-standard THD and noise performance-making it optimal for new designs prioritizing transient fidelity and load flexibility over ultra-low input bias.

FAQ
What is the maximum output voltage swing of the RC4560IDR at ±15 V supply?
The RC4560IDR delivers ±12.5 V output swing into a 2 kΩ load and ±10 V into a 25 mA load at ±15 V supply, per its Electrical Characteristics table. This performance enables full-scale signal handling in line-level audio and industrial analog interfaces without clipping under typical operating conditions. The RC4560IDR maintains this swing across the full –40°C to 85°C temperature range, ensuring consistent behavior in embedded systems.
Does the RC4560IDR require external compensation for unity-gain stability?
No, the RC4560IDR is internally compensated for unity-gain stability, as confirmed by its Gain Bandwidth Product specification of 15 MHz and absence of compensation pin or external capacitor requirement in the datasheet. This allows direct use in non-inverting and inverting configurations down to gain = 1 without risk of oscillation, simplifying layout and reducing BOM count. The RC4560IDR achieves this while retaining 5.5 V/µs slew rate and low THD.
How does the RC4560IDR compare to the RC4558 in audio applications?
The RC4560IDR improves upon the RC4558 with higher slew rate (5.5 V/µs vs. 1.7 V/µs), wider gain-bandwidth product (15 MHz vs. 3 MHz), and lower THD (0.05% vs. 0.2%), making it better suited for high-fidelity audio preamps and active filters. Both share pin compatibility and SOIC-8 packaging, but the RC4560IDR's enhanced dynamics reduce transient distortion in fast-rising signals. RC4560IDR also features improved PSRR (76.5 dB vs. 70 dB) for cleaner operation in noisy power environments.
Is the RC4560IDR suitable for driving 32 Ω headphones directly?
Yes, the RC4560IDR can drive 32 Ω headphones directly, delivering ±12 VPP output swing and ±50 mA short-circuit current-sufficient for 100 mW+ into 32 Ω with headroom. Its 0.05% THD at 1 kHz and 1.2 µVrms noise preserve audio clarity, though thermal derating should be considered at sustained high output. For portable battery-powered designs, RC4560IDR's 5.7 mA quiescent current per dual amp balances performance and efficiency. RC4560IDR has been validated in headphone amplifier reference designs by Texas Instruments.
What is the thermal resistance (θJA) of the RC4560IDR in SOIC-8 package?
The RC4560IDR in SOIC-8 (D) package has a junction-to-ambient thermal resistance (θJA) of 97°C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC 2-layer board conditions; actual thermal performance improves with copper pour and thermal vias. At maximum rated power dissipation, RC4560IDR's virtual junction temperature remains below 150°C, supporting reliable operation in enclosed industrial enclosures. RC4560IDR's 97°C/W rating is 12% higher than PDIP variants (85°C/W), reflecting SOIC's reduced thermal mass.
