NE5532D8R2 - Dual Low-Noise Op Amp | onsemi | Audio
MPN： NE5532D8R2 ✗ 停產NE5532D8R2 概覽
An operational amplifier is an analog integrated circuit that uses high-gain differential amplification with negative feedback. A dual operational amplifier contains two amplifier channels in one package, allowing a circuit to process two related signals or to build stereo, differential, or multi-stage analog functions. The internally compensated architecture simplifies stable operation in typical closed-loop analog applications, while the low-noise characteristics make the device relevant to audio and measurement circuits.
The NE5532 family is commonly associated with audio preamplification, microphone stages, active filters, and general instrumentation. The verified search results specifically describe the NE5532D8R2 as an internally compensated dual low-noise operational amplifier and identify its package as 8-SOIC. They do not provide a complete manufacturer electrical table, so detailed values such as input noise density, slew rate, bandwidth, common-mode range, output swing, input bias current, and temperature limits are marked as data needed rather than inferred.
Typical circuit implementation places each amplifier channel in a feedback network, with external resistors setting closed-loop gain and filtering behavior. Decoupling capacitors should be placed close to the supply pins, and the unused channel should be configured according to the manufacturer’s recommended practice rather than left floating. The SOIC footprint supports conventional surface-mount assembly, although actual board layout, thermal behavior, and signal integrity still require validation.
NE5532D8R2 pricing and detailed electrical performance must be confirmed against current authorized distributor inventory and the manufacturer datasheet. The verified distributor page reports current purchasing access, but the supplied data does not include numeric prices, stock quantities, or lead times. This page therefore distinguishes verified catalog facts from specifications requiring datasheet confirmation.

典型應用
NE5532D8R2 適用於 7 應用s: Audio Preamplifier, Active Audio Filter, Instrumentation Signal Conditioning, Microphone and Line-Level Buffering, Test and Measurement Front End, Power-Supply Feedback and Control, Stereo Audio Electronics.
Audio Preamplifier
The NE5532D8R2 fits dual-channel audio preamplification because the verified source identifies a 2-circuit, internally compensated low-noise operational amplifier in an 8-SOIC package. The two channels can process left and right signals or form two gain stages. Use local supply decoupling and a feedback network selected for the source impedance and target gain. The verified data does not specify noise density, bandwidth, slew rate, output swing, or input bias current, so those values must be obtained from the manufacturer datasheet before setting gain-bandwidth or distortion targets.
推薦
Active Audio Filter
The NE5532D8R2 can implement active filtering stages where two amplifier channels provide convenient signal conditioning around a passive RC network. Its internally compensated architecture makes it a practical general-purpose choice, but the exact usable bandwidth and stability margin are not present in the supplied verified data. Design the filter using manufacturer-recommended compensation limits, check output loading, and simulate the complete network rather than relying only on nominal gain. Proper grounding and short feedback paths help preserve low-noise behavior.
推薦
Instrumentation Signal Conditioning
The dual-channel configuration is useful for instrumentation signal conditioning, including amplification, buffering, or active filtering of low-level analog signals. The verified catalog description supports a standard general-purpose dual amplifier, while the Rochester Electronics result identifies the device as an 8-pin low-noise operational amplifier. Because input offset, bias current, common-mode range, and noise specifications are not supplied, the circuit designer must verify source impedance, sensor grounding, and signal bandwidth against the manufacturer datasheet.
推薦
Microphone and Line-Level Buffering
A low-noise dual operational amplifier can buffer microphone or line-level signals in audio equipment, test systems, and analog front ends. The NE5532D8R2’s two channels allow related buffering or gain functions in one 8-SOIC package. The supplied sources do not confirm input-referred noise, input capacitance, or output-drive limits, so microphone impedance and cable capacitance should be checked experimentally and against the manufacturer’s recommended operating conditions.
推薦
Test and Measurement Front End
The NE5532D8R2 is suitable for generic analog front-end stages in test and measurement equipment, such as buffered inputs, gain blocks, or active filters. Its dual-channel 8-SOIC arrangement simplifies board organization when two signals must be conditioned. The verified data does not state input noise, offset voltage, common-mode range, or temperature limits; therefore, measurement accuracy specifications should be established from the official datasheet and validated with the actual source impedance, bandwidth, and supply arrangement.
推薦
Power-Supply Feedback and Control
The dual amplifier can be used in feedback, error-amplifier, and analog-control circuits where two related channels provide flexibility. Its internally compensated general-purpose topology is useful for closed-loop regulator and power-control experiments, but the supplied sources do not verify input common-mode limits, output swing, slew rate, or stability behavior. Keep the feedback loop short, provide local bypass capacitance, and verify the operating-point limits before using the device in a new power-conversion design.
推薦
Stereo Audio Electronics
The NE5532D8R2 is a natural fit for stereo analog paths where two channels share a package and the design requires low-noise general-purpose amplification. It can be used in preamplifier, line-stage, or active-filter blocks, provided the verified supply range and the datasheet’s electrical limits are respected. The 8-SOIC footprint supports compact surface-mount assembly, but pin orientation, exposed thermal behavior, and decoupling placement must be checked against the final PCB and assembly documentation.

- Audio replacement ecosystem (對比OPA2604)
設計說明
Place supply bypass capacitors close to the NE5532D8R2 supply pins and keep input, feedback, and output traces short. The verified data confirms an 8-SOIC surface-mount package but does not provide a manufacturer layout recommendation, so the final placement should follow the current ON Semiconductor datasheet and PCB stack-up. Short ground returns are particularly important when both channels amplify low-level audio or instrumentation signals.
Do not treat every dual amplifier with an 8-SOIC outline as a drop-in replacement. Confirm pin numbers, supply pins, input offsets, common-mode range, output swing, input bias current, noise, bandwidth, and stability requirements before substituting NE5532D, NE5532P, TL072, OPA2134, OPA2604, or AD826. The supplied alternatives data does not fully verify those electrical and pinout details.
Keep high-impedance input nodes physically small and away from supply, clock, and digital return paths. For microphone and sensor inputs, account for source capacitance, cable capacitance, and the amplifier’s input network before selecting feedback resistors or compensation capacitors. The supplied sources identify a low-noise dual amplifier but do not quantify noise or input capacitance, so PCB prototyping and measurement remain important.
合規資訊
The supplied verified results do not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status for NE5532D8R2. AEC-Q100 is recorded as not_applicable because no automotive qualification claim appears in the supplied data; this is not an automotive qualification statement.
