Product details
Overview
NE5532PS from Texas Instruments is a dual low-noise operational amplifier in plastic small-outline (SOIC-8) package, delivering 5 nV/√Hz input noise voltage at 1 kHz, 10 MHz unity-gain bandwidth, and ±3 V to ±20 V supply range. It drives 600 Ω loads with 32 VPP output swing at ±18 V supplies and is specified for 0°C to 70°C operation in professional audio signal conditioning.
For engineers reviewing the NE5532PS datasheet, NE5532PS pinout, NE5532PS application, or NE5532PS equivalent, key selection criteria include input noise performance, output drive capability into low-impedance loads, thermal resistance (95°C/W), common-mode rejection (100 dB typ), and compatibility with legacy NE5532/NE5532A designs requiring SOIC packaging.
Technical Context
The NE5532PS integrates two internally compensated op-amps optimized for unity-gain stability, featuring input protection diodes and short-circuit protected outputs. Its bipolar input stage delivers low input bias current (200–800 nA typ) and high dc gain (100 V/mV typ), while the output stage supports rail-to-rail peak-to-peak swing up to 32 V under ±18 V supplies.
Designed for wide-bandwidth analog signal paths, it achieves 9 V/µs slew rate and maintains 110 dB crosstalk attenuation at 1 kHz. The device operates across ±3 V to ±20 V supplies, with common-mode input range extending to ±13 V and CMRR of 100 dB typical - enabling robust performance in differential and single-ended configurations.
Key Specifications

Pinout & Package
NE5532PS uses an 8-pin plastic small-outline integrated circuit (SOIC-8) package with standard pinout and gull-wing leads. Thermal resistance is 95°C/W (junction-to-ambient), and the device is available taped and reeled (suffix R).

| 3 | Amplifier 1 Non-Inverting Input | Differential input node referenced to common-mode range of ±13 V at ±15 V supply |
| 4 | Negative Supply (VCC–) | Return path for dual-supply operation; must be decoupled near pin |
| 5 | Amplifier 2 Non-Inverting Input | Independent input for second channel; shares same bias current and noise specs |
| 6 | Amplifier 2 Inverting Input | Second differential input with identical offset and CMRR characteristics as Pin 2 |
| 7 | Amplifier 2 Output | Matched output stage to Pin 1; crosstalk attenuation >110 dB at 1 kHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-noise operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532P | Dual-in-line (PDIP-8) package; θJA = 85°C/W; identical electrical specs | Through-hole assembly; higher thermal mass but larger footprint; no reflow compatibility | Select NE5532P only for prototyping, legacy repair, or through-hole production where SOIC is not supported |
| RC4558P | Higher input noise (10 nV/√Hz), lower slew rate (1.7 V/µs), narrower bandwidth (3 MHz), no input protection diodes | Cost-sensitive consumer audio; unsuitable for professional-grade mic preamps or line drivers | Choose RC4558P only when budget constraints outweigh noise and drive requirements |
Compared with NE5532P and RC4558P, the NE5532PS provides SOIC-8 surface-mount compatibility with identical low-noise and high-drive performance, while RC4558P trades off critical audio specifications for cost - making NE5532PS optimal for space-constrained, high-fidelity analog signal chains.

FAQ
What is the maximum supply voltage rating for NE5532PS?
The NE5532PS has absolute maximum supply voltage ratings of +22 V on VCC+ and –22 V on VCC–, per the official Texas Instruments datasheet SLOS075C. Operation beyond ±20 V is not recommended, and the recommended operating range is ±3 V to ±20 V. Exceeding these limits risks permanent damage, especially under sustained load or elevated temperature conditions. Always observe derating curves and ensure proper decoupling when operating near maximum ratings. The NE5532PS must never be operated outside its specified absolute maximums.
Does NE5532PS require external compensation capacitors?
No, the NE5532PS is internally compensated for unity-gain stability and does not require external compensation capacitors. This simplifies PCB layout and eliminates tuning dependencies across temperature and unit-to-unit variation. The internal compensation ensures stable closed-loop operation down to gain = 1 across the full specified temperature range (0°C to 70°C). External capacitors may be added only for specialized applications like decompensation or bandwidth limiting, but doing so voids guaranteed stability per the datasheet. The NE5532PS remains fully functional without any external compensation components.
Is NE5532PS pin-compatible with NE5532APS?
Yes, NE5532PS is pin-compatible with NE5532APS - both use identical SOIC-8 (PS) packaging and share the same pinout, electrical interface, and mechanical footprint. The primary difference lies in specification: NE5532APS guarantees maximum input noise voltage (≤6 nV/√Hz), whereas NE5532PS specifies typical noise (5 nV/√Hz) without maximum limits. For designs requiring guaranteed noise ceiling, NE5532APS is preferred; otherwise, NE5532PS offers identical functionality and layout compatibility in cost-sensitive applications.
What is the thermal resistance (θJA) of NE5532PS?
The junction-to-ambient thermal resistance (θJA) of NE5532PS is 95°C/W, as specified in the Texas Instruments datasheet SLOS075C. This value applies to the plastic small-outline (PS) package mounted on a standard JEDEC 2-layer test board with 1 in² copper area per side. Actual θJA in end-user PCBs depends on copper pour, via count, and airflow; designs dissipating >300 mW should include thermal relief pads and additional copper to approach the 95°C/W baseline. The NE5532PS thermal performance is distinct from the PDIP-8 version (NE5532P), which has θJA = 85°C/W.
Can NE5532PS operate from a single supply?
The NE5532PS is designed for dual-supply operation (±3 V to ±20 V) and is not characterized for true single-supply use. While it can function with a split virtual ground (e.g., using resistive divider + decoupling cap), its input common-mode range extends only to ±13 V at ±15 V supplies and does not include the negative rail - limiting headroom in true single-rail configurations. Input protection diodes also assume symmetrical supplies. For dedicated single-supply applications, TI recommends alternatives like TL072 or OPA2134. The NE5532PS performs optimally and reliably only in properly implemented dual-supply systems.
