NE5532DG - Dual Low-Noise Op Amp, 10 MHz, 16-SOIC | onsemi
MPN： NE5532DG ✓ 啟用中NE5532DG 概覽
An operational amplifier is an analog signal-processing IC that uses high-gain differential feedback to amplify the voltage difference between its inputs. In this device category, the NE5532 family occupies the low-noise operational-amplifier tier of the broader voltage-amplifier and semiconductor hierarchy. It is intended for applications requiring cleaner signal amplification than standard general-purpose amplifiers while retaining the simplicity of an integrated, internally compensated dual amplifier.
The NE5532DG provides two amplifier channels in one package, reducing board area compared with two separate single-channel devices. Its internally compensated architecture is intended to simplify closed-loop operation without requiring an external compensation network. The verified product information identifies bipolar construction, a maximum input offset voltage of 5 mV, a 10 MHz bandwidth rating, and low-noise performance appropriate to professional audio and measurement equipment.
NE5532DG operates from a broad 3 V to 20 V supply range, allowing it to operate from conventional 5 V, 12 V, and 18 V analog rails. The wide supply range is useful in mixed industrial, consumer, and laboratory equipment, although the exact input and output swing limits must be taken from the manufacturer datasheet before finalizing a high-amplitude design. Because it is a bipolar amplifier, supply-current and common-mode behavior must also be checked against the system power budget.
Typical uses include stereo audio preamplification, active filters, mixer input stages, audio buffers, sensor signal conditioning, laboratory instrumentation, and general feedback control. In each case, the two channels can amplify related signals or perform separate functions, while the low-noise internal design helps preserve small signals through the analog chain. Output loading, stability, and allowable output swing remain application-dependent.
When placing NE5532DG on a PCB, place input, feedback, and decoupling connections to minimize parasitic pickup and maintain short feedback-loop paths. Follow the manufacturer’s recommended bypass capacitance and layout guidance, and verify stable operation with the actual source impedance, load, and supply configuration. Decoupling capacitors should be positioned close to the power pins to suppress supply ripple at the amplifier.
This product page combines the verified distributor identity, package information, operating-range details, cross-reference findings, and practical design considerations. It distinguishes verified NE5532DG attributes from missing manufacturer-specific values and highlights the need to confirm exact pin names, noise density, slew rate, input bias current, output current, and lifecycle status in the current manufacturer documentation.

典型應用
NE5532DG 適用於 6 應用s: Stereo Audio Preamplifier, Active Audio Filters, Audio Mixing and Buffering, Instrumentation Signal Conditioning, Test and Measurement Front Ends, Industrial Control and Sensor Interfaces.
Stereo Audio Preamplifier
The NE5532DG fits stereo audio preamplifier signal paths because it provides two amplifier channels, low-noise operation, and a 10 MHz bandwidth rating in one 16-SOIC package. Each channel can implement a conventional inverting or non-inverting gain stage ahead of a line-level output. The verified 3 V to 20 V supply range permits use with common 5 V, 12 V, and 18 V analog rails, although the exact output swing must remain within the device limits for the selected load. Keeping both audio channels on one package can simplify routing and reduce footprint, but layout symmetry and independent bypassing remain important. Confirm noise, distortion, slew rate, and output-current requirements against the manufacturer data before fixing the gain and load values.
推薦
Active Audio Filters
NE5532DG is well suited to active low-pass and high-pass filter stages used in audio crossovers, equalizers, and signal-conditioning networks. Its low-noise classification helps preserve small signals, while the verified 10 MHz bandwidth provides useful frequency-range headroom beyond audio frequencies. The dual-channel arrangement allows closely related filter sections to be implemented together and can improve matching when identical layouts are used. Component tolerances and op-amp behavior still influence cutoff accuracy and phase response, so the manufacturer’s recommended gain and stability conditions should be followed. Verify input and output swing at the maximum expected signal level, and place filter resistors and capacitors close enough to the amplifier pins to minimize parasitic feedback and noise pickup.
推薦
Audio Mixing and Buffering
The two channels in NE5532DG can provide independent buffering between a mixing stage and line-level outputs, reducing the risk of loading the preceding circuit. Low-noise operation is valuable when the mixed signal is relatively small, and the verified 3 V to 20 V range accommodates several conventional analog supply levels. The internally compensated architecture avoids requiring an external compensation network in conventional feedback configurations. Designers should still check the amplifier’s output-current capability and voltage swing against the mixer impedance and load. Feedback components should be placed close to the relevant input pins, while supply bypass capacitors should connect directly to the package power terminals with minimal loop area.
推薦
Instrumentation Signal Conditioning
NE5532DG can condition low-level signals from sensors and measurement circuits when a low-noise dual amplifier is preferred over a general-purpose device. Its verified 10 MHz bandwidth supports higher-frequency measurement signals than basic audio-only requirements, and the two channels can amplify or buffer complementary inputs. The bipolar architecture and maximum input offset voltage of 5 mV make careful DC-error budgeting important in precision measurements; the complete offset and bias-current specifications must be obtained from the datasheet. Use a clean reference or regulated supply, decouple the device locally, and avoid long high-impedance traces that increase leakage and interference. Gain, common-mode range, and output swing must be validated before installation in a precision instrument.
推薦
Test and Measurement Front Ends
The NE5532DG is applicable to buffer and gain stages in test equipment because its low-noise characteristics and 10 MHz bandwidth can preserve small signals ahead of an ADC, comparator, or measurement block. Two channels permit related differential or sequential functions to share one package, although the available results do not provide a verified differential-output architecture. The designer should use suitable resistors to set gain, confirm input bias-current effects, and verify that the operating point remains inside the common-mode and output-swing limits. PCB leakage and contamination can dominate very-high-impedance measurements, so guard techniques and clean boards may be more important than the amplifier itself. Follow the manufacturer’s application examples for stable feedback and decoupling.
推薦
Industrial Control and Sensor Interfaces
NE5532DG can serve in low-level industrial control paths when the signal bandwidth is below 10 MHz and the circuit requires a low-noise dual amplifier. The wide 3 V to 20 V supply range supports multiple industrial analog rails, while the internally compensated configuration simplifies closed-loop implementation. In sensor interfaces, the designer must verify input bias current, common-mode voltage range, offset voltage, and output swing rather than assuming that a wide supply rating covers all operating conditions. Protection, filtering, and grounding are especially important near sensors and switching equipment. Keep sensitive input traces away from high-current paths, use local supply bypassing, and ensure that connected loads remain compatible with the amplifier’s output-drive capability under worst-case temperature and supply conditions.

- Internally compensated implementation (對比AD823)
設計說明
Place the input, inverting-input, feedback-resistor, and bypass-capacitor connections close to NE5532DG to minimize parasitic feedback and noise pickup. Keep each feedback loop compact and route it away from power-switching nodes and high-current return paths. Use a continuous ground plane where appropriate, but avoid creating accidental copper loops beneath sensitive amplifier inputs. Because the supplied material identifies a 16-SOIC package but does not provide the authoritative terminal map, use the current onsemi package drawing before assigning PCB pads or routing signals.
Decouple the NE5532DG close to its power pins and verify bypass values against the manufacturer guidance. The part supports 3 V to 20 V supplies, but the usable input range, output swing, common-mode range, and supply-current limits are separate constraints. Check quiescent-current demand at the actual operating voltage and add margin for the source supply’s tolerance and transient response. Use a stable, low-noise supply when the signal chain depends on low-noise amplification; regulator noise cannot be corrected merely by choosing a low-noise amplifier.
Do not treat package-family similarity or an online equivalence claim as proof of drop-in compatibility. The verified search results discuss AD823, OPA2604, and OPA2134, but they do not establish orderable suffixes in the same 16-SOIC footprint. Before replacing NE5532DG, compare the exact pin map, supply range, input offset, input bias current, noise, bandwidth, slew rate, output swing, output-current capability, and thermal limits. Also account for different loading, biasing, and stability behavior even when the final pin names appear identical.
The verified 10 MHz bandwidth identifies useful small-signal capability, but it does not guarantee stable operation at every closed-loop gain or with every load. Evaluate noise and distortion together because a wide-bandwidth amplifier can amplify high-frequency interference as well as the desired signal. For audio and instrumentation paths, use short traces, adequate return paths, and input filtering where needed. Confirm capacitive-load stability and output-swing margin in the actual configuration, especially when driving long cables, analog-to-digital converter inputs, or downstream connector stages.
合規資訊
The supplied search results do not provide authoritative compliance declarations for NE5532DG. Compliance must be confirmed using the current onsemi product page or declaration documents. The component is identified as commercial temperature, but that description alone does not establish AEC-Q100 qualification.
