NE5534AP - 30V 10MHz Low-Noise Op Amp | Texas Instruments
MPN： NE5534AP ✓ 啟用中NE5534AP 概覽
An operational amplifier is a voltage-controlled differential amplifier used to amplify the voltage difference between its two inputs. Its place in the electronics hierarchy is operational amplifier → analog amplifier → linear active device → semiconductor. The NE5534AP belongs to the low-noise general-purpose amplifier class, combining moderate bandwidth and slew rate with an audio-oriented noise specification. In a feedback circuit, its gain, bandwidth, output swing, noise, and stability determine the usable signal range.
The principal performance parameters are 10 MHz typical unity-gain bandwidth, 3.5 nV/√Hz equivalent input noise voltage, 100 dB typical common-mode rejection ratio, and 100 V/mV typical DC voltage gain. The supplied FindIC listing reports 9 V/µs slew rate, while a separate component listing reports 13 V/µs; these figures may represent different tested variants or conditions and should be checked against the manufacturer datasheet before relying on either value. A 32 V typical peak-to-peak output swing is listed at ±18 V supplies.
Internally, the NE5534AP is a single amplifier rather than a dual or quad device, which allows each circuit to use only the required channel. Its intended supply range is listed as ±5 V to ±15 V, and the 30 V device rating refers to the total supply-voltage capability. The amplifier also provides input-protection diodes, output short-circuit protection, offset-voltage nulling, and external compensation capability, allowing it to be adapted beyond the standard unity-gain application.
Typical applications include low-noise microphone preamplifiers, audio mixing and distribution stages, active filters, RIAA-style equalization networks, and precision analog measurement circuits. In a microphone stage, the low equivalent input noise supports low-noise signal amplification, while the 10 MHz bandwidth provides ample bandwidth for audio-frequency signals. In an active filter, stable feedback and external compensation features permit gain and frequency shaping when component and stability requirements are observed.
Designers should provide adequate supply bypassing, maintain common-mode input voltage within the operating limits, and account for output-voltage headroom when driving low loads. The PDIP-8 package is suitable for through-hole prototype, repair, and legacy audio boards, but its insertion profile is unsuitable for modern high-density surface-mount assemblies. Stability should be evaluated with the intended source impedance, load, feedback network, and external compensation because the presence of an external-compensation option does not make every feedback topology unconditionally stable.
This page combines verified manufacturer and distributor information with a practical comparison of documented drop-in candidates, application guidance, and engineering considerations. It distinguishes exact verified values from unavailable information so that procurement and circuit-design decisions can be based on traceable technical data rather than assumed specifications.

典型應用
NE5534AP 適用於 6 應用s: Low-Noise Microphone Preamplifier, Audio Mixing and Distribution Stage, Precision Active Audio Filter, RIAA and Equalization Network, Precision Analog Signal Conditioning, Legacy Audio Equipment Repair.
Low-Noise Microphone Preamplifier
The NE5534AP fits a low-level microphone preamplifier because its specified equivalent input noise voltage is 3.5 nV/√Hz and its 10 MHz unity-gain bandwidth is substantially greater than the audio band. The amplifier can provide voltage gain in a conventional inverting or non-inverting feedback network while preserving headroom for the source signal. Its major trade-off is the power dissipation and output-voltage limitation at the extreme end of the ±5 V to ±15 V supply range, so the microphone level, input bias, and required gain should be established before fixing the gain network.
推薦
Audio Mixing and Distribution Stage
The NE5534AP is suitable for an audio summing, buffering, or distribution stage because it combines a 3.5 nV/√Hz typical noise specification with a 10 MHz typical unity-gain bandwidth and 100 V/mV typical DC gain. In a mixer channel, it can drive a controlled impedance while preserving the low-frequency and midrange audio content. Because it is a single amplifier, one package provides only one signal path; a dual-device approach may be preferable when two closely related channels must fit within a restricted board area.
推薦
Precision Active Audio Filter
The NE5534AP can implement an active low-pass or band-pass section when its 10 MHz typical unity-gain bandwidth and low-noise characteristics are suitable for the filter. The amplifier's documented external-compensation capability provides design flexibility, but stability still depends on the selected topology, resistor ratios, source impedance, and load. Designers should use a stable feedback configuration and verify both frequency response and distortion. The device's 32 V typical peak-to-peak output swing is specified at ±18 V supplies, so the actual output range must be reduced when operating from lower rails.
推薦
RIAA and Equalization Network
The NE5534AP is appropriate for a low-noise RIAA or general equalization network because its 3.5 nV/√Hz typical equivalent input noise voltage helps limit added noise in the low-amplitude signal path. A 10 MHz unity-gain bandwidth gives substantial margin above the audio frequencies typically handled by passive or active equalization networks. The passive network determines the intended frequency response, while the amplifier must maintain adequate phase margin with the selected resistor and capacitor values. Input bias and output-loading requirements should be evaluated against the actual cartridge or source impedance.
推薦
Precision Analog Signal Conditioning
The NE5534AP can amplify or buffer modest differential signals in instrumentation when the signal bandwidth is below its 10 MHz typical unity-gain bandwidth and its supply requirements are satisfied. Its listed 100 dB typical common-mode rejection ratio is useful when the wanted differential signal is smaller than common-mode interference. The amplifier should be treated as a general-purpose precision analog building block rather than an instrumentation amplifier, so source balancing, input filtering, and offset or bias-current compensation remain important parts of the complete signal chain.
推薦
Legacy Audio Equipment Repair
The 8-pin PDIP package makes NE5534AP particularly useful for repairing or maintaining older audio equipment that uses a through-hole NE5534 socket. The 3.5 nV/√Hz typical noise specification and 10 MHz bandwidth are appropriate for many line-level and preamplifier stages. Before powering a repaired board, compare the replacement's offset, bias current, output swing, and compensation requirements with the original device. The DIP outline makes mechanical replacement straightforward, but pin-one orientation and socket artwork still require verification.

主要差異化特點
- Verified low-noise A-grade device selection (對比NE5534P)

- Documented 10 MHz bandwidth for audio and precision analog use (對比TL972IP)
設計說明
Do not treat the 30 V rating as the preferred operating voltage. The verified listing identifies ±5 V to ±15 V as the nominal supply range, and the 32 V typical output swing is stated at ±18 V. At lower supplies, usable output swing is reduced. Before substituting a listed alternative, also compare offset voltage, input bias current, noise density, output current, and compensation requirements; matching an 8-pin PDIP outline does not by itself prove equivalent performance.
For a new PCB, preserve the standard 8-pin PDIP footprint and verify pin-one orientation against the official manufacturer drawing. In a repair or retrofit, inspect the socket for corrosion and confirm that the replacement's offset-null and compensation pins correspond to the original schematic. The verified excerpts confirm the package but do not provide the terminal names, so the official pin drawing must be used before drilling, wiring, or socket replacement.
Place the device's supply-decoupling network close to its pins and keep the ground return short to reduce the impedance seen by transient supply current. Because the NE5534AP is intended for bipolar supplies up to ±15 V, check the absolute maximum total supply voltage and power dissipation against the lowest available supply rail tolerances. The verified excerpts do not specify manufacturer-recommended capacitor values, so use the official application guidance rather than an assumed universal value.
合規資訊
The supplied excerpts identify a general-purpose audio operational amplifier but do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable to the stated general-purpose application rather than an extracted qualification claim.
