NE5532AN - Dual Low-Noise 10 MHz Op Amp | onsemi
料号： NE5532AN ✓ 量产中NE5532AN 概述
A low-noise operational amplifier is an analog signal-conditioning device that amplifies the voltage difference between its two inputs while seeking low added noise and low distortion. In the product hierarchy, the NE5532AN belongs to the operational-amplifier family, which is part of amplifier ICs and, more broadly, analog semiconductors. Its two amplifiers share one package while providing independent input, output, and supply connections.
The principal verified characteristics include a dual amplifier configuration, internally compensated operation, a 10 MHz gain-bandwidth product, and an 8-DIP package. The associated NE5532x family is specified for operation over a ±5 V to ±15 V supply range. The commercial NE5532x temperature range is stated as 0°C to 70°C, while the SA5532x family is specified from -40°C to +85°C. Exact input-offset, input-bias-current, output-voltage, and output-current limits were not included in the supplied data and therefore remain unspecified on this page.
Internally compensated operation allows each amplifier to operate as a stable closed-loop stage without an external compensation network. This simplifies analog circuit design while preserving the low-noise characteristics valued in audio equipment. The stronger output-drive capability described in the manufacturer data helps the amplifier maintain low distortion when driving the next stage or a termination load. The 10 MHz gain-bandwidth figure provides useful bandwidth for low-frequency signal conditioning and audio preamplification rather than high-speed instrumentation applications.
Typical uses include stereo audio preamplifiers, active tone-control stages, mixer input stages, headphone-driver interfaces, active crossover filters, and low-level signal conditioning. Its dual configuration is particularly useful when a board needs two similar amplifier channels, such as left and right audio paths. For lower-voltage or extended-temperature requirements, the related SA5532x grade should be evaluated separately rather than assuming NE5532AN covers those conditions.
The primary design consideration is supply-headroom management: the stated family specification applies from ±5 V to ±15 V, so the circuit must remain within that operating range at every temperature and load condition. Decoupling capacitors should be placed close to the supply pins, and the unused amplifier in a dual package should be configured according to the manufacturer guidance rather than left floating.
This page consolidates the verified package, supply-range, temperature-class, bandwidth, and cross-reference information for the NE5532AN, then adds application guidance, strict same-package drop-in comparisons, and practical selection criteria for engineers evaluating this dual low-noise operational amplifier.

典型应用
NE5532AN 适用于 6 应用s: Stereo Audio Preamplifier, Active Audio Crossover, Audio Mixer Input Stage, Headphone Buffer, Low-Level Sensor Signal Conditioning, Test and Measurement Buffer.
Stereo Audio Preamplifier
The NE5532AN fits a stereo audio preamplifier because it combines two internally compensated low-noise amplifiers in one 8-DIP package. Its verified 10 MHz gain-bandwidth product provides bandwidth beyond typical audio-band signal shaping, while the family specification supports ±5 V to ±15 V supplies. Each channel can provide gain and buffering ahead of a line-level amplifier or mixer. Compared with a switching implementation, this analog topology does not introduce switching ripple into the audio path. The primary checks are the exact input-offset and noise limits, output swing, and stability at the intended closed-loop gain.
推荐
Active Audio Crossover
The NE5532AN can implement the two active filter sections required by a stereo crossover, with one amplifier assigned to each signal path. Its 10 MHz gain-bandwidth product leaves substantial loop-gain margin above audio crossover corner frequencies, while internal compensation simplifies stable filter implementation. The device is best placed in low-level mixers and line-stage crossovers where its low-noise behavior is useful. Component tolerances, filter-Q stability, and the target load determine whether the stage is adequate. Confirm output-drive and slew-rate data before using it to drive unusually low impedances.
推荐
Audio Mixer Input Stage
For an audio mixer input, the NE5532AN provides low-level amplification while presenting the dual-channel topology needed for stereo source conditioning. The verified 10 MHz gain-bandwidth product supports audio-frequency amplification, and the NE5532x ±5 V to ±15 V supply range covers conventional split-supply mixer rails. Placing the device close to the line input allows weak source signals to be amplified before later stages add noise. Its suitability for a particular mixer depends on source impedance, gain setting, output loading, and headroom. Exact input-bias-current and distortion figures were not supplied and should be reviewed before finalizing the gain network.
推荐
Headphone Buffer
The NE5532AN can buffer an audio source before a headphone or line driver when the amplifier is configured as a unity-gain follower. The verified stronger output-drive capability, relative to standard operational amplifiers, makes this use more practical than assuming an unspecified general-purpose amplifier can drive the required load. Its 10 MHz gain-bandwidth product also exceeds typical audio requirements. Nevertheless, headphone impedance, minimum stable gain, output-current limit, and distortion must be verified from the complete manufacturer data. The NE5532AN is preferable when low noise and conventional dual-DIP availability matter more than integrated rail-to-rail features.
推荐
Low-Level Sensor Signal Conditioning
The NE5532AN is suitable for low-level analog signal conditioning when the source bandwidth is well below its 10 MHz gain-bandwidth product and the system uses compatible supply rails. The low-noise operational-amplifier architecture can amplify sensor outputs before ADC or filtering stages, while internal compensation simplifies closed-loop design. Its conventional ±5 V to ±15 V family range favors industrial analog systems rather than modern single-rail portable systems. A practical design must check offset, bias current, common-mode range, output swing, and noise against the sensor. Those detailed limits were not included in the verified excerpt, so the manufacturer datasheet must complete the design review.
推荐
Test and Measurement Buffer
The NE5532AN can serve as a dual buffer in a low-frequency test and measurement front end when the measured signal is below the verified 10 MHz gain-bandwidth limit. The dual package provides channel economy for differential or paired instrumentation stages, and the improved output-drive capability described by the manufacturer helps preserve signal integrity at the buffer output. The design should minimize offset and noise error, use an appropriate gain network, and avoid loading the source beyond the amplifier's input and output capabilities. Because common-mode range, output swing, and output-current limits were not included in the supplied data, those values must be confirmed before accepting the buffer configuration.

设计说明
The verified NE5532x family range is ±5 V to ±15 V. Confirm the actual negative and positive rail voltages at the amplifier pins under minimum supply conditions, and do not assume that operation below ±5 V preserves the published performance. Place the supply-bypass capacitors close to pins 4 and 8 with a short, low-impedance ground return. This matters especially in audio boards because supply impedance can convert current transients into distortion that is not intrinsic to the amplifier.
Keep the two amplifier channels symmetrical when matching stereo gain and phase. Route each feedback component close to its corresponding input and output, avoid long traces around high-impedance inputs, and return the bypass-capacitor ground directly to the device ground pin. Since the NE5532AN is a through-hole DIP-8, keep the analog signal path away from switching-node copper and high-current return paths. Grounding and lead placement are especially valuable when the amplifier is used near a mixer bus.
Do not treat the family-level NE5532x temperature range as proof that every NE5532AN orderable variant has identical qualification or marking. Likewise, a shared 8-DIP outline does not automatically prove that a substitute has identical input-bias behavior, output swing, noise, distortion, or supply limits. Before substituting an alternative, compare pin functions, minimum stable gain, common-mode range, output-drive capability, and the unused-channel recommendation directly between the two manufacturer datasheets.
