Product details
Overview
RC4560IPWR from Texas Instruments is a dual high-gain, wide-bandwidth operational amplifier optimized for audio preamplifier, active filter, and industrial measurement applications. It operates from ±2 V to ±18 V, delivers 5.5 V/µs slew rate, 15 MHz gain-bandwidth product, 1.2 µVrms input noise, and 0.05% THD at 1 kHz with 5 V output into 2 kΩ.
For engineers reviewing the RC4560IPWR datasheet, RC4560IPWR pinout, RC4560IPWR application, or RC4560IPWR equivalent, this device is selected for low-noise analog signal conditioning where bandwidth, slew rate, and distortion performance are critical in ±15 V systems.
Technical Context
The RC4560IPWR implements a bipolar-input, internally compensated op-amp architecture with rail-to-rail input common-mode range (±14 V at ±15 V supply) and ±12.5 V output swing into 25 mA loads. Its 100 dB large-signal voltage gain and 90 dB CMRR support precision DC-coupled amplification in instrumentation front-ends.
Designed as a higher-performance upgrade to RC4558, it achieves 15 MHz GBW and 5.5 V/µs slew rate while maintaining compatibility with legacy 8-pin SOIC/TSSOP footprints - enabling drop-in replacement in existing audio and measurement PCB layouts without signal integrity compromise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±2 V to ±18 V - supports dual-rail operation across industrial and audio supply rails including ±12 V and ±15 V systems |
| Slew Rate | 5.5 V/µs (typ) - enables clean 20 kHz full-scale audio signal reproduction without slew-induced distortion |
| Gain Bandwidth | 15 MHz (typ) - allows stable unity-gain buffer or high-Q active filter design up to ~1 MHz |
| Input Noise | 1.2 µVrms (typ, RIAA-weighted) - suitable for microphone preamplifiers requiring sub-2 µV noise floor |
| THD + N | 0.05% (typ, 1 kHz, 5 Vpp, 2 kΩ) - meets Hi-Fi audio line-level signal path requirements |
| Input Offset Voltage | 6 mV (max) - permits DC-coupled sensor amplification without excessive nulling circuitry |
| Common-Mode Range | ±14 V (at ±15 V supply) - accommodates inputs near supply rails in single-supply derived bias networks |

| 3 | Output (Channel A) | Capable of ±12.5 V swing into 25 mA load - drives headphones or active filter stages directly |
| 4 | V− (negative supply) | Must be connected to stable negative rail; decoupling capacitor required within 1 cm |
| 5 | Non-inverting input (Channel B) | Independent second channel input - enables stereo preamp or dual-sensor signal paths |
| 6 | Inverting input (Channel B) | Separate feedback node for Channel B - no crosstalk with Channel A per TI characterization |
| 7 | Output (Channel B) | Matched AC performance to Channel A - supports balanced output or dual-channel filtering |
| 8 | V+ (positive supply) | Requires local 0.1 µF ceramic decoupling to ground; shared rail with Channel A/B |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Higher input bias current (300 nA vs 500 nA max), identical GBW (10 MHz), lower noise (0.95 µVrms) | Preferred in ultra-low-noise phono preamps; less suited for high-Z sensor buffering due to higher IIB | Select NE5532DR when noise floor is primary constraint and input impedance >100 kΩ is not required |
| TL072CDR | JFET input (50 pA IIB), lower slew rate (13 V/µs), higher noise (18 nV/√Hz), 3 MHz GBW | Better for high-impedance source interfacing (e.g., piezoelectric sensors); insufficient bandwidth for >100 kHz active filters | Select TL072CDR when input impedance >1 MΩ is mandatory and bandwidth ≤50 kHz suffices |
Compared with NE5532DR and TL072CDR, the RC4560IPWR offers superior slew rate and bandwidth for transient-rich audio and measurement signals, while maintaining lower input bias than JFET types - making it optimal for mixed-signal front-ends requiring both speed and moderate Zin.

FAQ
What is the maximum operating supply voltage for the RC4560IPWR?
The RC4560IPWR supports dual-supply operation from ±2 V to ±18 V. Absolute maximum ratings specify ±18 V supply voltage; however, recommended operation is limited to ±16 V to ensure long-term reliability and thermal stability under continuous load conditions. Exceeding ±16 V may increase junction temperature beyond safe limits, especially in TSSOP-8's 149°C/W thermal resistance.
Does the RC4560IPWR support single-supply operation?
Yes, the RC4560IPWR supports single-supply operation with appropriate input biasing. Its input common-mode range extends to within 1 V of the negative rail and 2 V below the positive rail (e.g., –14 V to +14 V at ±15 V supplies), allowing use with VCC = 30 V and VEE = 0 V if the inputs are biased to mid-supply. External resistive dividers or dedicated bias networks are required to establish correct DC operating points.
What is the thermal resistance (θJA) of the RC4560IPWR in its TSSOP-8 package?
The RC4560IPWR in TSSOP-8 (PW) package has a junction-to-ambient thermal resistance (θJA) of 149°C/W, as specified in the TI datasheet. This value assumes standard JEDEC 2-layer board conditions (1-inch² copper pad). Actual thermal performance improves significantly with enhanced PCB copper area, internal planes, or thermal vias - critical for sustained ±12.5 V output into 25 mA loads.
Can the RC4560IPWR replace the RC4558 in existing designs?
Yes, the RC4560IPWR is a direct functional upgrade to the RC4558 in TSSOP-8 footprint. It shares identical pinout, supply voltage range, and output drive capability but adds 15 MHz GBW (vs 3 MHz) and 5.5 V/µs slew rate (vs 0.6 V/µs). No PCB changes are required, though layout review is advised to verify stability margins given the higher bandwidth.
Is the RC4560IPWR RoHS compliant and lead-free?
Yes, the RC4560IPWR is RoHS compliant and features NiPdAu (NIPDAU) lead finish. Per TI's Package Option Addendum, it carries "Yes" for RoHS status and Level-1 moisture sensitivity rating with peak reflow tolerance of 260°C - fully compatible with standard lead-free reflow profiles used in modern SMT assembly lines.
