NE5534P - 30V, 10MHz Low-Noise Op Amp | Texas Instruments
MPN: NE5534P ✓ Hoạt độngNE5534P Tóm tắt
An operational amplifier is an analog integrated circuit that uses high-gain differential amplification to increase a voltage difference between its input terminals. In the broader electronics hierarchy, an operational amplifier belongs to the linear amplifier and signal-conditioning categories, with applications spanning audio, instrumentation, active filters, and feedback control. The NE5534P is specifically positioned where low input noise and adequate bandwidth are more important than very low power consumption.
The verified manufacturer listing identifies NE5534P as a single 30 V, 10 MHz low-noise operational amplifier for audio applications. The supplied search data also identifies a 13 V/µs slew rate, a 3.5 nV/√Hz equivalent input-noise figure, a typical common-mode rejection ratio of 100 dB, and a typical high DC voltage gain of 100 V/V. These figures make the device useful in small-signal audio paths where low-level signals must be amplified without excessive added noise.
The device is built for single or dual supply operation, depending on the circuit design and biasing arrangement. Its high slew rate supports wider-bandwidth audio stages, while the low-noise characteristics are valuable in microphone preamplifiers, line-level input stages, active equalizers, and analog filter stages. Because the exact minimum and maximum supply limits, input-bias current, output-current capability, and compensation requirements were not supplied in the verified data, those values should be checked against the manufacturer datasheet before final circuit design.
Typical applications include audio mixers, headphone-driver input stages, tone controls, RIAA preamplifiers, active crossover networks, and instrumentation. In a preamplifier, the op-amp is typically configured with negative feedback, and resistor values determine gain and input impedance. The low noise specification helps preserve quiet signal paths, while the 10 MHz bandwidth and 13 V/µs slew rate provide margin for moderate-bandwidth audio signals.
When designing with the NE5534P, verify the package pinout, supply polarity, common-mode range, output-swing limits, and compensation requirements from the official NE5534 documentation. Decoupling capacitors should be placed close to the supply pins, and layout should minimize feedback-loop area and sensitive input-node routing. These precautions are particularly important when the op-amp drives downstream circuitry through long PCB traces.
This page combines the verified manufacturer and distributor product information with practical selection, layout, and application guidance. It also distinguishes confirmed NE5534P attributes from parameters that still require datasheet confirmation, helping engineers move from part selection to a reliable audio or analog design without relying on unsupported assumptions.

Ứng dụng tiêu biểu
NE5534P phù hợp cho 6 Áp dụngs: Audio Microphone Preamplifier, Active Audio Equalizer, Mixer Input Stage, Active Crossover and Filter, Headphone Driver Input, Precision Audio Signal Conditioning.
Audio Microphone Preamplifier
The NE5534P fits low-level microphone and instrument preamplifiers because the verified data identifies it as a low-noise audio operational amplifier and lists equivalent input noise of 3.5 nV/√Hz. Configure it with negative feedback and resistor-defined gain, while checking the source impedance and complete input-noise curve. Its 10 MHz typical unity-gain bandwidth provides more bandwidth than many audio-focused stages require, and the 13 V/µs typical slew rate helps preserve larger signals. The key trade-off is that the exact bias current, common-mode range, and output-swing limits were not supplied, so microphone biasing and headroom must be verified against the datasheet before production.
Được đề xuất
Active Audio Equalizer
The NE5534P is appropriate for active equalizer and tone-control sections because its listed 3.5 nV/√Hz noise supports quiet signal amplification while the 10 MHz typical bandwidth covers moderate audio frequencies. Use the op-amp in a standard inverting or non-inverting feedback topology, with resistor and capacitor values setting the filter response. Confirm whether the exact circuit requires the device’s offset or compensation connections and verify stability with the selected gain and load. Compared with a slower precision op-amp, the NE5534P offers more bandwidth, but the actual audible benefit depends on the filter topology, source impedance, and overall system noise.
Được đề xuất
Mixer Input Stage
The NE5534P can serve as a mixer input amplifier when the design needs low noise, moderate bandwidth, and a single-channel signal path. Its listed 13 V/µs slew rate helps handle larger transients while the 3.5 nV/√Hz input-noise figure helps avoid raising the mixer’s noise floor. Place the feedback network close to the amplifier and keep the input trace away from switching and motor-control paths. The part’s single-amplifier configuration means a stereo mixer may require multiple devices or a dual amplifier such as NE5532D. Check the NE5534P’s exact pinout, supply limits, and load capability before finalizing the mixer schematic.
Được đề xuất
Active Crossover and Filter
The NE5534P is a reasonable candidate for active crossover, anti-aliasing, and small-signal audio filter circuits because its 10 MHz typical unity-gain bandwidth provides useful headroom above the audible range. The 3.5 nV/√Hz noise specification helps maintain low-level signal integrity, while the 13 V/µs typical slew rate can improve large-signal behavior in higher-order filter stages. Component tolerances, op-amp gain-bandwidth behavior, and stability determine the final response. Verify the exact compensation arrangement and maximum output swing for the selected supply rails. The verified data does not establish guaranteed AC parameters, so design calculations should use the manufacturer’s complete test conditions.
Được đề xuất
Headphone Driver Input
The NE5534P is useful as an input or voltage-gain stage ahead of a headphone amplifier because it provides low noise and a higher typical slew rate than a basic general-purpose op-amp. The verified specifications show 10 MHz typical unity-gain bandwidth and 13 V/µs typical slew rate, which help preserve signal shape in moderate-bandwidth audio paths. The device does not replace a power headphone driver by itself; it should drive a suitable output buffer or power stage. Check output-current capability and voltage swing, which are marked as data-needed, before selecting the gain and load. Use short, quiet routing between the NE5534P and the downstream driver.
Được đề xuất
Precision Audio Signal Conditioning
The NE5534P can be used for general audio signal conditioning when low input noise and moderate bandwidth are more important than minimum power or rail-to-rail operation. The verified manufacturer description specifically positions it for audio applications, while the supplied technical data lists 100 dB typical common-mode rejection and 100 V/V typical high DC voltage gain. Those figures can help reject common-mode disturbances and amplify small differential signals in suitable bias conditions. Verify the common-mode input range, output swing, offset, and bias current before using it with sensor-level or battery-powered signals. Stable feedback layout and local supply decoupling are important for preserving low-noise performance.

Ghi chú thiết kế
Place the NE5534P close to the signal source and feedback components, and keep the input node short and isolated from switching-node copper. The device is an 8-pin PDIP, so lead inductance and long analog traces are more significant than they would be in a compact surface-mount implementation. Route the feedback loop as short as practical, maintain a stable return path, and place supply-decoupling capacitors close to the supply pins. The verified data does not provide a manufacturer-specific layout drawing, so use the official datasheet for pin-specific guidance.
Verify the supply arrangement, input common-mode range, and output-swing limits before selecting the NE5534P supply voltage. The verified data gives a 30 V maximum device rating and a 32 V peak-to-peak typical output swing under a specified ±18 V test condition, but it does not provide all operating limits for every use case. Do not interpret the 30 V rating as permission to operate at 30 V regardless of load or package conditions. Confirm absolute maximum ratings and thermal limits in the current manufacturer datasheet.
Do not substitute NE5532D or another dual amplifier solely because it has a similar low-noise description. NE5534P is a single amplifier in an 8-pin PDIP package, and the complete NE5534 pin map may include package-specific connections that differ from other families. Before redesigning or substituting, compare pin numbers, offset or compensation pins, supply requirements, noise, bandwidth, slew rate, output current, and stability. The verified cross-reference data identifies related alternatives but does not prove universal PCB-level drop-in compatibility.
