NE5532DX - Dual Low-Noise Op Amp, 8-SOIC | onsemi
N.º da peça: NE5532DX ✓ AtivoNE5532DX Visão geral
An operational amplifier is a high-gain, differential-input analog IC that uses external feedback to control gain, bandwidth, and signal conditioning. The NE5532 belongs to the broader hierarchy of operational amplifiers, analog signal-chain ICs, and semiconductors. Internally compensated dual amplifiers simplify closed-loop design because no external compensation network is required for ordinary voltage-feedback applications.
The verified device data identifies a gain-bandwidth product of 10 MHz, slew rate of 8 V/µs, and full-power bandwidth of 140 kHz. These figures make the part useful for high-quality audio preamplification, active filtering, microphone conditioning, and general instrumentation. Its dual configuration also reduces board area by placing two amplifiers in one package.
The NE5532 architecture provides improved noise performance, output-drive capability, and small-signal bandwidth compared with standard general-purpose amplifiers. Internal frequency compensation supports stable operation with conventional feedback networks, while the two amplifier channels can process independent signals or work together in differential and filtering circuits.
Typical uses include professional audio input stages, low-level sensor amplification, telephone-channel amplification, active crossover networks, and control circuits. When using the part in audio equipment, input impedance and source impedance should be considered alongside the gain-bandwidth product. Higher closed-loop gains reduce usable bandwidth, so the amplifier should not be treated as a wideband op amp merely because its gain-bandwidth product is 10 MHz.
For PCB implementation, decouple each power pin with a local high-frequency bypass capacitor and keep return-current paths short. Input and feedback traces should be physically separated to reduce parasitic coupling. The 8-SOIC package is leaded and readily hand-solderable, but careful thermal design is still required when driving low-impedance loads continuously.
This product record combines verified NE5532DX specifications, distributor availability references, package details, cross-reference alternatives, and application-focused design guidance. It distinguishes electrical compatibility from mere functional similarity and identifies where replacement parameters require verification before production use.

Aplicações típicas
NE5532DX é adequado para 6 aplicaçãos: Professional Audio Preamplifier, Microphone Preamplifier, Active Audio Filter, Precision Instrumentation Signal Conditioning, Telephone Channel Amplification, Industrial Control and Signal Amplification.
Professional Audio Preamplifier
The NE5532DX is well suited to professional audio preamplification because its verified 10 MHz gain-bandwidth product and 8 V/µs slew rate support low-level signal conditioning without the limitations of a basic general-purpose amplifier. Two internally compensated amplifiers can handle left and right channels in one 8-SOIC package. Designers should keep the feedback loop short, maintain symmetrical input routing, and verify source impedance against the input-bias specification in the complete datasheet. The 140 kHz full-power bandwidth supports audio-band amplification, while the dual format reduces PCB area. Thermal performance and output swing should be checked when driving unusually low-impedance mixer or headphone stages.
Recomendado
Microphone Preamplifier
For microphone preamplification, the NE5532DX combines a low-noise dual-amplifier architecture with a 10 MHz gain-bandwidth product and 8 V/µs slew rate. The two channels can support stereo microphones or separate signal paths while reducing component count. The verified full-power bandwidth of 140 kHz extends beyond the principal audio band, but achievable closed-loop gain remains constrained by the 10 MHz gain-bandwidth product. Input impedance, source impedance, and bias-current requirements should be confirmed before choosing the gain network. A local bypass capacitor at the positive supply pin and a short, quiet ground return are important because microphone signals are especially susceptible to supply and layout noise.
Recomendado
Active Audio Filter
The NE5532DX is appropriate for active audio crossover and equalization stages requiring low distortion and predictable closed-loop behavior. Its verified 10 MHz gain-bandwidth product leaves bandwidth margin above the audio range, while the internally compensated topology simplifies conventional voltage-feedback filter implementation. Each channel can implement an independent section or cooperate in a multi-stage filter. Component tolerances, loading, and the resulting closed-loop gain determine the actual response, so simulated values must be checked on the physical board. Keep the resistor and capacitor loop compact to minimize parasitic coupling, and use the 8 V/µs slew rate as an input when driving nearby filter stages with large low-frequency transients.
Recomendado
Precision Instrumentation Signal Conditioning
The NE5532DX can condition low-level instrumentation signals where low noise and useful high-frequency response are more important than minimum cost. Its 8 V/µs slew rate and 10 MHz gain-bandwidth product provide adequate small-signal performance for many sensor and test circuits, while the dual configuration supports two channels on a shared board. The supply-voltage range and input-offset specifications were not present in the supplied excerpts, so those parameters must be confirmed before selecting the device for precision measurements. Feedback resistors should use suitable tolerances, input traces should avoid switching nodes, and the bypass capacitor should be placed directly beside the device to prevent supply ripple from entering the analog signal path.
Recomendado
Telephone Channel Amplification
Telephone-channel amplification is a verified target application for the NE5532 family and is compatible with the NE5532DX’s combination of low noise, 10 MHz gain-bandwidth product, and 8 V/µs slew rate. The dual amplifier can process two channels or provide gain and filtering functions within one signal path. Interface protection should be added around externally connected line inputs because the supplied excerpts do not specify the input-protection structure or absolute maximum ratings. Keep the line-side network physically separated from sensitive amplifier feedback paths, and validate gain, bandwidth, and distortion against the actual telephone-channel source impedance. Local supply bypassing and a quiet return plane remain essential because the useful signal level can be small.
Recomendado
Industrial Control and Signal Amplification
The NE5532DX can amplify and shape low-level signals in industrial control boards when the operating supply range, input offset, output swing, and load capability have been verified. Its dual topology allows one channel to condition a sensor while the other handles a reference or feedback signal. The 10 MHz gain-bandwidth product and 8 V/µs slew rate are useful for modest closed-loop bandwidth and moderate edge rates, but they do not eliminate the need for protection in an industrial environment. Add input clamps or filtering as appropriate, route high-current outputs away from analog inputs, and maintain continuous ground references. Thermal analysis is essential if either amplifier continuously drives a lower-than-nominal load impedance.

Notas de projeto
Place the supply bypass capacitor immediately beside the NE5532DX power pins and connect it to a low-impedance ground return. Because the supplied excerpts do not specify the allowable supply-voltage range or input common-mode range, verify those limits against the manufacturer datasheet before applying a rail. This is particularly important in dual-supply audio, industrial, and telephone-channel circuits where incorrect rail selection can cause distortion or damage.
Keep each op-amp feedback loop compact and separate the input trace from the output trace to reduce parasitic oscillation and crosstalk. Route both amplifier grounds through a quiet return path rather than through switching or motor-current wiring. The verified 10 MHz gain-bandwidth product and internal frequency compensation support ordinary voltage-feedback layouts, but high loop gain still requires attention to board leakage, capacitance, and lead inductance.
Do not assume that every NE5532-family ordering code is a direct substitute for NE5532DX. Confirm the package suffix, pinout, supply range, common-mode range, output swing, offset voltage, noise, bandwidth, and slew rate. The verified NE5532DX figures are 10 MHz gain-bandwidth product, 8 V/µs slew rate, and 140 kHz full-power bandwidth. A different suffix can change qualification, packaging, temperature range, or electrical grade even when the amplifier family is similar.
Informações de conformidade
The supplied verified excerpts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the package or manufacturer.
