NE5532PSR - Dual 10 MHz Low-Noise Audio Op Amp | Texas Instruments
MPN: NE5532PSR ✓ Hoạt độngNE5532PSR Tóm tắt
An operational amplifier is an analog integrated circuit that uses high-gain differential amplification with negative feedback to create stable, precise gain. The NE5532 belongs to the dual-operational-amplifier, voltage-feedback, low-noise operational-amplifier hierarchy and is widely used in professional audio, preamplifier, mixer, filter, and signal-conditioning circuits. Its two independent amplifiers share the same package while providing separate input, output, and supply connections.
The NE5532 family's key characteristics include a typical 10 MHz unity-gain bandwidth, 5 nV/√Hz input noise at 1 kHz, and a typical 100 dB common-mode rejection ratio. It also provides a typical high DC voltage gain of 100 V/mV and an output swing specified at 32 V peak-to-peak under ±18 V supplies and 600 Ω loading. The listed 9 V/µs slew rate supports faithful reproduction of higher-frequency audio and waveform signals.
Internally compensated for unity gain, the amplifier simplifies conventional audio-board design because no external frequency-compensation network is required. Input-protection diodes and output short-circuit protection improve robustness, while low distortion and high slew rate make the device suitable for demanding small-signal stages. The verified operating-temperature range shown for NE5532PSR is 0°C to 70°C, corresponding to its standard general-purpose product classification.
Typical uses include stereo preamplification, active crossover and equalizer circuits, mixing consoles, headphone-buffer stages, audio test equipment, and general low-noise signal conditioning. In each case, the NE5532 can be paired with external resistors and capacitors to establish gain, bandwidth, and filtering. The dual configuration reduces board area when two audio channels must be processed with matching device characteristics.
Designers should account for supply headroom, output-current limits, stability, and the operating region of the chosen feedback network. Decoupling capacitors should be placed close to the supply pins, while input and feedback resistors should avoid long high-impedance traces that increase noise pickup. The 8-SO surface-mount package also requires adequate solderability and assembly controls for automated production.
This product record consolidates verified manufacturer and distributor information, current pricing references, same-family alternatives, and application-specific engineering guidance. It adds practical comparison and design context beyond the basic distributor listing while clearly separating verified specifications from values that still require confirmation from an individual alternative's datasheet.

Ứng dụng tiêu biểu
NE5532PSR phù hợp cho 6 Áp dụngs: Stereo Audio Preamplifier, Active Crossover and Equalizer, Audio Mixing Console, Headphone Output Buffer, Precision Audio Signal Conditioning, Audio Test and Measurement Equipment.
Stereo Audio Preamplifier
The NE5532PSR fits a stereo preamplifier because it combines two amplifiers in one 8-SO package while providing 5 nV/√Hz typical input noise at 1 kHz and a 10 MHz typical unity-gain bandwidth. Each channel can use the same gain-setting and filtering topology, preserving channel consistency in the same device family. The 9 V/µs typical slew rate gives useful headroom for transient audio signals, while the documented output-drive capability and short-circuit protection support practical line-level stages. Designers should still validate distortion, output swing, and stability at the lowest planned gain and into the actual load impedance.
Được đề xuất
Active Crossover and Equalizer
The NE5532PSR is appropriate for active crossover and equalizer networks requiring low-noise amplification with substantial bandwidth. Its 10 MHz typical unity-gain bandwidth provides more signal-path range than the audio band, while the 5 nV/√Hz typical input noise at 1 kHz helps preserve low-level program material. Two independent channels in one 8-SO package simplify a stereo crossover layout. Filter stability remains critical, so the engineer should evaluate component tolerances, the feedback network, and the resulting noise gain rather than assuming that a unity-gain-stable amplifier is suitable at every practical gain.
Được đề xuất
Audio Mixing Console
A mixing-console input amplifier benefits from the NE5532PSR's documented low-noise characteristics, high DC gain, and dual-channel integration. The 5 nV/√Hz typical input noise at 1 kHz and 100 dB typical common-mode rejection ratio provide useful starting points for low-level microphone or line stages, although source impedance and resistor selection will influence the total noise. The 9 V/µs typical slew rate supports rapid signal transitions, and the 8-SO package simplifies repetitive board routing. Designers should verify maximum output swing, load compatibility, channel-to-channel layout symmetry, and thermal conditions in the finished console.
Được đề xuất
Headphone Output Buffer
The NE5532PSR can serve as a low-noise headphone or line-output buffer when the intended load is compatible with its output-drive capability. The amplifier's 5 nV/√Hz typical noise density, 10 MHz typical bandwidth, and 9 V/µs typical slew rate support clean small-signal amplification without introducing an unnecessary conversion stage. Its dual 8-SO construction can buffer two channels in a compact layout. However, the verified data does not state the continuous output-current limit or a headphone-impedance recommendation, so the design must check those datasheet limits and verify channel stability into the selected load.
Được đề xuất
Precision Audio Signal Conditioning
The NE5532PSR is useful for precision low-level signal conditioning after sensors, transducers, or balanced audio sources. Its 5 nV/√Hz typical input noise at 1 kHz limits the amplifier's own contribution in many audio-frequency measurement paths, while the 100 dB typical common-mode rejection ratio supports rejection of common-mode interference. The 10 MHz typical unity-gain bandwidth and 9 V/µs typical slew rate accommodate signals beyond the nominal audio range. The system designer should still include input protection, account for bias-current error, and verify operation within the actual common-mode and output-swing boundaries.
Được đề xuất
Audio Test and Measurement Equipment
The NE5532PSR can form the signal-conditioning core of audio test equipment because it combines low noise, wide bandwidth, and dual-channel operation in a surface-mount package. The 10 MHz typical unity-gain bandwidth supports generation and measurement of signals well above the audible range, while the 5 nV/√Hz typical noise at 1 kHz improves sensitivity for low-amplitude test channels. The 9 V/µs typical slew rate helps preserve waveform shape. For calibrated instruments, engineers should account for offset, bias current, resistor tolerance, output loading, and the actual distortion specifications listed in the manufacturer test tables.

Ghi chú thiết kế
Do not substitute the device solely because another dual amplifier uses an 8-pin outline. Verify the exact pin mapping, supply limits, input common-mode range, output swing, unity-gain stability, noise, slew rate, and load drive against the NE5532 datasheet. The supplied replacement research identifies OPA2604 and AD823 as possible pin-layout alternatives, but it does not provide a complete parameter comparison. Perform a full worst-case review before treating any candidate as a production drop-in replacement.
Keep the two channels symmetrical when the NE5532PSR drives paired stereo paths. Place input, feedback, compensation, and supply-decoupling components close to their associated pins, and minimize the trace length of high-impedance input nodes to reduce noise pickup. Use a solid ground-plane layout and route output returns without sharing narrow paths with sensitive input returns. Although the verified excerpts do not specify a recommended PCB land pattern, the manufacturer package drawing and layout guidance remain authoritative.
Confirm the regulator rail, total output-load current, and amplifier quiescent current before sizing the supply and decoupling network. The verified data identifies a 15 V supply specification and tests output swing at ±18 V, but it does not provide the complete current-limit or quiescent-current tables. Use those manufacturer limits to calculate dissipation and headroom; do not infer continuous output drive from the documented 32 V peak-to-peak swing alone.
Thông tin tuân thủ
The supplied excerpts identify NE5532PSR as a standard general-purpose amplifier but do not explicitly state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status. Confirm current declarations on the Texas Instruments product page and manufacturer datasheet.
