NE5532NG - Dual Low-Noise 10 MHz Op Amp | onsemi
N.º de pieza: NE5532NG ✓ ActivoNE5532NG Descripción general
An operational amplifier is an analog integrated circuit that uses high-gain feedback to amplify the difference between voltages applied to its input terminals. The NE5532NG belongs to the operational-amplifier hierarchy: dual operational amplifier, voltage-feedback amplifier, amplifier IC, and ultimately analog semiconductor. Its internal compensation avoids an external compensation network in typical closed-loop configurations, which helps simplify designs while maintaining stable operation.
The verified manufacturer information identifies the NE5532NG as an internally compensated dual low-noise operational amplifier. The family is described as offering better noise performance than standard amplifiers such as the 1458, while also combining excellent DC and AC characteristics with high output-drive capability, high unity-gain and maximum-output-swing bandwidth, low distortion, high slew rate, and input-protection diodes. These characteristics suit precision audio stages, active filters, buffers, and general instrumentation.
The 10 MHz gain-bandwidth product provides useful bandwidth for audio-frequency and moderate-frequency signal paths. The 3 V to 20 V supply-voltage span accommodates conventional analog rails, although the selected dual-supply arrangement must remain within that range. Because the NE5532NG is supplied in an 8-pin PDIP package, it is particularly suitable for leaded through-hole assemblies, prototypes, repair work, and production boards designed around a DIP footprint.
Typical applications include stereo audio preamplification, microphone-stage amplification, active equalization filters, line-level buffers, tone-control circuits, and instrumentation signal conditioning. In dual-channel audio designs, both amplifier sections can be used symmetrically for left and right signal paths. The device is also useful where low distortion and low noise are more important than the very low power consumption or small footprint of newer CMOS amplifiers.
For a new design, confirm the exact load impedance, output swing, supply configuration, input common-mode range, input bias current, slew rate, and noise spectrum from the manufacturer datasheet before committing the circuit. Decoupling capacitors should be placed close to the supply pins, and the unused channel should be configured according to the datasheet rather than left floating.
This page consolidates verified distributor and manufacturer information, same-footprint replacement candidates, comparison parameters, and practical design cautions. It distinguishes confirmed values from parameters that still require verification, helping engineers move from part selection to a defensible circuit design without relying on unverified generic amplifier claims.

Aplicaciones típicas
NE5532NG es adecuado para 6 aplicacións: Stereo Audio Preamplifier, Active Equalization Filter, Microphone and Instrumentation Preamplifier, Line-Level Buffer, Tone-Control and Mixing Circuit, Test and Measurement Signal Conditioning.
Stereo Audio Preamplifier
The NE5532NG fits a stereo line-level preamplifier because its dual architecture provides two matched amplifier sections in one 8-pin PDIP package, while the verified family data emphasizes low noise, low distortion, high slew rate, and strong output-drive capability. Each channel can use the device as a voltage-feedback gain stage ahead of a line output or power amplifier. The confirmed 10 MHz gain-bandwidth product provides useful bandwidth beyond the core audio range, while the 3 V to 20 V supply span supports several conventional analog rail combinations. In a new design, verify the required closed-loop gain against the amplifier's gain-bandwidth curve, check output swing into the next stage, and confirm that the selected supply voltage remains within the stated operating range.
Recomendado
Active Equalization Filter
The NE5532NG is suitable for dual-section active equalization because it combines two amplifiers, internal compensation, a 10 MHz gain-bandwidth product, and a family description centered on low noise and low distortion. Each amplifier section can implement a first- or higher-order active filter with passive R and C networks, allowing left and right channels to share one package. Internal compensation simplifies feedback design, but stability, gain limits, and maximum output swing must still be respected at the target frequency. The verified 3 V to 20 V operating range permits common supply choices, yet the actual filter output amplitude should be kept below the datasheet limits. Component tolerances and the amplifier's gain-bandwidth behavior will determine whether precision response requires additional calibration.
Recomendado
Microphone and Instrumentation Preamplifier
The NE5532NG can be used in microphone or instrumentation preamplifier stages where low input-referred noise, adequate bandwidth, and dual-channel economy are valuable. The verified datasheet description specifically identifies the device as a dual low-noise operational amplifier and states that it provides better noise performance than standard amplifiers such as the 1458. Its 10 MHz gain-bandwidth product supports gain calculations above the audio band, although the exact voltage-noise density, input bias current, and common-mode range are not available in the supplied excerpts and must be checked before biasing a high-impedance source. The 8-PDIP package also simplifies through-hole prototyping and repair. Keep the input network close to the amplifier pins and verify the source impedance because resistor thermal noise and input capacitance can influence the practical noise floor.
Recomendado
Line-Level Buffer
The NE5532NG works as a line-level buffer when the source and destination require low noise, low distortion, and reliable drive rather than minimum power. The verified family characteristics include high output-drive capability, high slew rate, high unity-gain and maximum-output-swing bandwidth, and input-protection diodes. These attributes are valuable when driving a downstream impedance that is heavier than the source can accommodate directly. The internally compensated dual device can provide one unity-gain buffer per channel, reducing package count in stereo equipment. Before implementation, check the exact output-current and capacitive-load limits, because the supplied excerpts do not provide numeric drive ratings. Keep the input at a defined voltage, connect the unused amplifier according to the datasheet, and avoid assuming that high slew rate alone guarantees stability with every load or cable.
Recomendado
Tone-Control and Mixing Circuit
The NE5532NG is well matched to passive tone-control and audio-mixing circuits because its dual sections can process two signal paths while preserving low noise and low distortion. A Baxandall-style or passive summing design can place the amplifier at the end of the network, where low-noise gain and output-drive characteristics help retain the original signal quality. The confirmed 10 MHz gain-bandwidth product is substantially above the principal audio band, while the 3 V to 20 V supply range supports common analog operating voltages. The practical limitation is output swing: attenuating the signal before amplification can avoid clipping in the active path. Verify offset, bias current, and output swing for the specific network, and keep the dual sections arranged symmetrically when channel matching is important.
Recomendado
Test and Measurement Signal Conditioning
The NE5532NG can support low-noise signal conditioning in test and measurement equipment when a through-hole dual amplifier and audio-grade characteristics are preferable to a very small CMOS device. The verified 10 MHz bandwidth supports common low-frequency measurement paths, while low noise, low distortion, and high output-drive capability help preserve weak source signals. Each amplifier section can provide gain, inversion, buffering, or active filtering. Its 3 V to 20 V operating range allows several supply configurations, but the exact input common-mode range and output-swing boundaries must be checked before setting the operating point. Use short, guarded signal traces, provide local supply bypassing, and verify ground-return paths so that the practical noise floor reflects the amplifier rather than the PCB or supply network.

Notas de diseño
Confirm the complete supply arrangement against the verified 3 V to 20 V operating range before powering the board. Place the required bypass capacitors close to pins 4 and 8, with the ground return kept short. The supplied material does not specify capacitor values, input common-mode range, quiescent current, or output-swing limits, so those figures must be taken from the manufacturer datasheet rather than inferred. In dual-rail operation, verify that the total rail span and each node's absolute voltage remain acceptable.
Treat pin 8 as the positive supply and pin 4 as the negative supply according to the displayed 8-PDIP dual-op-amp pinout. Keep input traces short, separate from output routing, and use a stable ground reference around pins 4 and 8. Because the device is a sensitive audio amplifier, avoid long loops and shared high-current return paths. The unused amplifier section should be configured according to the manufacturer guidance rather than allowing an input to float.
Do not treat a cross-reference name as proof of identical electrical behavior. NJM5532, NL8802, LM833NG, and SA5532P appear in the supplied NE5532 comparison material, but the excerpts do not provide complete offset, noise, bias-current, slew-rate, output-swing, or temperature data. Before substituting any candidate, compare pin functions, supply range, common-mode range, load capability, noise density, and stability with the NE5532NG datasheet. Also confirm whether the exact suffix denotes commercial or extended-temperature grade.
