NE5532ADRE4 - Dual 10MHz Low-Noise Op Amp for Audio | TI
N.º da peça: NE5532ADRE4 ✓ AtivoNE5532ADRE4 Visão geral
A low-noise operational amplifier is an analog integrated circuit that amplifies voltage differences while contributing minimal intrinsic noise. The NE5532 belongs to the operational-amplifier hierarchy used for audio preamplification, mixing, buffering, filtering, and instrumentation. Its 5 nV/√Hz typical input-noise characteristic is especially relevant when the amplified signal is sourced from a high-impedance sensor or a low-level microphone.
The device provides 10 MHz typical unity-gain bandwidth, 9 V/µs typical slew rate, 100 dB typical common-mode rejection, and 100 V/mV typical DC voltage gain. These characteristics support audio-band operation with ample bandwidth for feedback networks and active filters. The dual configuration reduces component count in stereo circuitry, while the 8-SOIC package is compatible with automated surface-mount assembly.
The NE5532 uses a conventional voltage-feedback operational-amplifier architecture with two independent amplifiers. Each channel provides inverting and non-inverting inputs, an output, and a power-supply connection. Noise and common-mode rejection are important because they influence the signal-to-noise ratio and the degree to which unwanted supply or common-mode signals appear at the output. Operating from a dual supply also supports bipolar audio signals without biasing the source at mid-rail.
Typical applications include stereo audio preamplifiers, microphone amplifiers, line-level mixers, tone-control circuits, active crossover networks, and low-level audio buffers. In each case, the low-noise input stage helps preserve small signals, while the 10 MHz bandwidth and 9 V/µs slew rate provide margin for gain and phase shaping. Designers must still verify stability with the selected feedback network and load.
The principal design consideration is power-supply bypassing. Place the required input and output decoupling capacitors close to the device pins, keep output routing short, and avoid placing long traces beside noisy switching nodes. Decoupling values and stability guidance should be taken directly from the manufacturer datasheet and typical application circuit rather than inferred from the distributor summaries.
This page combines verified manufacturer information, distributor pricing, pin-compatible substitute references, and practical application guidance. The alternatives are explicitly limited to same-package drop-in candidates, while unavailable electrical details remain marked for validation against each candidate manufacturer’s current datasheet.

Aplicações típicas
NE5532ADRE4 é adequado para 6 aplicaçãos: Stereo Audio Preamplifier, Microphone Low-Noise Preamp, Audio Mixing Console, Active Tone-Control Network, Active Crossover and Filter, Line-Level Audio Buffer.
Stereo Audio Preamplifier
The NE5532ADRE4 fits a stereo audio preamplifier because its verified 5 nV/√Hz typical equivalent input noise at 1 kHz helps preserve low-level program material, while two amplifiers are integrated in one 8-SOIC package. The 10 MHz typical unity-gain bandwidth and 9 V/µs typical slew rate provide ample margin for typical audio gain and phase-shaping networks. Each channel can use inverting or non-inverting feedback arrangements, subject to the minimum stable gain specified by the manufacturer. The principal trade-off is that the NE5532x grade is specified from 0°C to 70°C, so extended-temperature industrial equipment should verify the appropriate grade or alternative.
Recomendado
Microphone Low-Noise Preamp
The NE5532ADRE4 is appropriate for a low-impedance or moderate-impedance microphone preamplifier when low input noise is important. Its 5 nV/√Hz typical equivalent input noise at 1 kHz provides a concrete basis for low-noise gain stages, while the 100 V/mV typical DC gain supports practical inverting stages with moderate feedback resistors. A 10 MHz unity-gain bandwidth can support audio-band filtering, although the chosen feedback network must preserve stability and the required signal bandwidth. Designers should minimize source resistance, maintain a clean return path, and confirm capacitor and bias-current requirements from the complete datasheet before production.
Recomendado
Audio Mixing Console
A NE5532ADRE4 can serve as a summing or mixing amplifier in an audio console because its dual-channel architecture reduces the component count for stereo or paired signal paths. The verified 9 V/µs slew rate and 10 MHz typical unity-gain bandwidth give designers margin for active gain stages, while the 100 dB typical common-mode rejection helps reduce unwanted common-mode pickup in balanced audio circuitry. Noise performance remains suitable for line-level processing at 5 nV/√Hz typical input noise. Feedback ratios, source impedances, and load impedances must be evaluated together to avoid compromising stability or headroom.
Recomendado
Active Tone-Control Network
The NE5532ADRE4 can implement active bass, treble, or midrange stages because its verified 10 MHz unity-gain bandwidth supports phase-shaping networks beyond the audible range, and its 9 V/µs slew rate reduces slew-related distortion on larger signals. Two channels allow linked stereo controls, while the low-noise input characteristic helps preserve program level through cascaded gain and summing stages. Component tolerances and the effective resistance seen by each amplifier should be calculated for the target frequency response. The ±5 V to ±15 V operating range also supports conventional bipolar audio rails, subject to output-swing and load requirements in the full datasheet.
Recomendado
Active Crossover and Filter
The NE5532ADRE4 is suitable for active crossover and audio-filter stages requiring more bandwidth than a basic general-purpose amplifier. Its 10 MHz typical unity-gain bandwidth allows the op amp to operate above audio frequencies while maintaining a 9 V/µs typical slew rate for signal transients. The 5 nV/√Hz typical input noise at 1 kHz is useful in low-level crossover channels where added noise would otherwise be exposed by subsequent gain. Each amplifier channel must remain within its stable feedback topology, and resistor and capacitor tolerances should be selected to control cutoff frequency and phase alignment between channels.
Recomendado
Line-Level Audio Buffer
The NE5532ADRE4 can buffer a line-level audio source before a longer cable, mixer input, or additional gain stage. Although the task is simpler than low-level preamplification, the verified 5 nV/√Hz typical input noise prevents the buffer from unnecessarily raising the system noise floor. The dual 8-SOIC package allows one part to buffer two channels, and its 10 MHz typical bandwidth provides more than enough bandwidth for conventional audio signals. Designers should check output-current capability, capacitive-load stability, and the required output swing against the load because those limits are not included in the supplied distributor summaries.

Notas de projeto
Place the manufacturer-recommended supply-bypass capacitors immediately adjacent to the power pins and use the shortest practical ground return. Keep both amplifier channels on the same side of the PCB where possible, minimize trace resistance in feedback networks, and avoid routing audio outputs near digital clocks, switching regulators, or inductors. Exact capacitance and layout dimensions should follow the current TI datasheet and its recommended land pattern.
Do not assume that any amplifier with eight pins is interchangeable: the NE5532ADRE4 is the 8-SOIC version of the NE5532x family, while NE5532x and SA5532x differ in specified temperature range. Also check the minimum stable gain, output-swing limits, load restrictions, and supply polarity against the original design. A substitute with the same outline is only a true drop-in candidate after its pin functions and electrical limits have been compared.
Keep feedback-loop geometry compact because the verified 10 MHz unity-gain bandwidth can make layout-induced phase shift significant. Use a stable feedback topology, avoid excessive capacitive loading on the output, and place channel-matching resistors and capacitors close to their associated amplifier pins. For low-level audio, use a quiet ground reference and avoid sharing high-current return paths with the input signal.
Informações de conformidade
The supplied excerpts do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals compliance. The NE5532x is an audio general-purpose amplifier, so AEC-Q100 qualification is not asserted.
