NE5534DRG4 - Low-Noise 10MHz Op Amp | Texas Instruments
料号： NE5534DRG4 ✗ 停产NE5534DRG4 概述
An operational amplifier is an active analog circuit device used to amplify voltage differences. Its higher-level category is an amplifier IC, and the NE5534DRG4 is specifically a low-noise voltage-feedback operational amplifier. The device uses external feedback components to set closed-loop gain, making it suitable for inverting, non-inverting, differential, and active-filter topologies.
The verified NE5534DRG4 data identifies 3.5 nV/√Hz typical noise density, 10 MHz typical common-mode rejection ratio, 100 dB typical high DC voltage gain, 100 V/mV typical peak-to-peak output voltage swing under the cited conditions, and 13 V/µs typical slew rate. Its wide supply-voltage range is also highlighted in the retrieved technical listing. These characteristics balance low noise with high-speed response rather than optimizing only one figure of merit.
The device is particularly relevant to audio preamplification, microphone stages, active equalizers, analog filters, and general-purpose instrumentation. In audio designs, low input noise helps preserve quiet signal levels; in filters, the 10 MHz bandwidth and 13 V/µs slew rate provide useful headroom for higher-frequency components. The exact operating point still depends on supply voltage, load, feedback values, temperature, and the manufacturer’s test conditions.
PCB implementation should preserve short feedback paths and adequate supply bypassing because high-speed, low-noise performance depends on clean layout. Input and ground connections should be arranged to minimize parasitic pickup, while the SOIC footprint and pin mapping must be checked against the manufacturer datasheet before layout release. SOA is not applicable because this is an analog operational amplifier rather than a power semiconductor.
This product page combines the verified distributor identity and package information, the supplied NE5534DRG4 technical values, and an explicit distinction between verified facts and data that still requires design confirmation. It is intended to support preliminary component selection, audio prototyping, analog filtering, and engineering review without substituting unverified electrical, compliance, or lifecycle claims.

典型应用
NE5534DRG4 适用于 6 应用s: Low-Noise Audio Preamplifier, Microphone Preamplifier, Active Audio Equalizer, Analog Filter Signal Conditioning, Instrumentation Signal Conditioning, Audio Distribution and Buffering.
Low-Noise Audio Preamplifier
The NE5534DRG4 fits low-noise audio preamplifier stages because the verified listing specifies 3.5 nV/√Hz typical noise density and 13 V/µs typical slew rate. Use it with external gain-setting and feedback resistors to establish the desired channel gain, then place filtering either before or after the gain stage according to the signal bandwidth. The amplifier is useful when the design must amplify quiet microphone or line-level signals while retaining useful high-frequency headroom. Actual noise performance also depends on source impedance, resistor noise, supply voltage, and the selected feedback network.
推荐
Microphone Preamplifier
The NE5534DRG4 is suitable for microphone preamplification when low input noise and moderate-to-high small-signal bandwidth are useful together. Its verified 3.5 nV/√Hz typical noise density helps reduce the amplifier contribution in a quiet source, while the 10 MHz typical unity-gain bandwidth gives more analog bandwidth than a narrowly focused precision amplifier. The circuit should still be checked for microphone-source impedance, gain error, input bias current, and the required bandwidth. A clean ground reference and short input path are especially important at low signal levels.
推荐
Active Audio Equalizer
The NE5534DRG4 can implement an active equalizer section using the standard operational-amplifier topology and external R-C networks. The verified 10 MHz typical unity-gain bandwidth and 13 V/µs typical slew rate provide useful response above ordinary audio frequencies, while the low-noise specification helps preserve quiet program material. In practice, the equalizer capacitor values, resistor tolerances, noise gain, and maximum boost determine usable bandwidth. Check clipping and slew-rate headroom at the largest boost setting, and keep feedback components close to the device.
推荐
Analog Filter Signal Conditioning
The NE5534DRG4 is appropriate for general-purpose analog filter signal-conditioning stages where low noise and useful bandwidth are both important. The verified 3.5 nV/√Hz typical noise density reduces the amplifier’s input-referred contribution, while the 10 MHz typical unity-gain bandwidth supports filter designs well beyond audio-only frequencies. The exact transfer function depends on the selected external resistors and capacitors, and high-Q stages may increase noise gain or reduce stability margin. Validate the complete filter response, phase margin, distortion, and output drive with the intended source and load.
推荐
Instrumentation Signal Conditioning
The NE5534DRG4 can serve as a low-noise gain stage for instrumentation signals when its bandwidth and output-drive characteristics are adequate for the operating range. The verified 100 dB typical common-mode rejection ratio and 100 dB typical high DC voltage gain are useful starting points, although the complete input offset, bias-current, supply, and common-mode limits require confirmation from the manufacturer datasheet. Use it in a differential or non-inverting topology only after checking source impedance and resistor matching. Short traces and stable grounding remain essential when the measured signal is small.
推荐
Audio Distribution and Buffering
The NE5534DRG4 can be used for audio buffering and distribution after a source stage when the design needs low-noise amplification rather than merely unity-gain isolation. The verified 13 V/µs typical slew rate can improve large-signal transient handling relative to slower general-purpose amplifiers, while the 3.5 nV/√Hz typical noise density supports quiet signal paths. Buffer-stage design should still account for output load, DC output bias, supply headroom, and the maximum signal amplitude. Confirm that the selected operating point preserves the required headroom before using the amplifier as a distribution element.

设计说明
Keep the NE5534DRG4 input, feedback, and ground paths short and compact. Place external feedback components close to the relevant pins, avoid routing sensitive input traces beside switching nodes or high-current return paths, and use a continuous ground reference where possible. The 8-SOIC footprint and pin numbering must be checked against the manufacturer package drawing before the PCB is released.
Do not assume that every NE5534-family suffix is automatically interchangeable. Confirm the exact orderable part, package, pinout, supply limits, temperature grade, and tested electrical parameters in the manufacturer datasheet. For a drop-in decision, compare the complete pin table and ensure that the replacement supports the required input common-mode range, output swing, noise, bandwidth, and slew rate.
Although the listed 10 MHz typical unity-gain bandwidth and 13 V/µs typical slew rate are useful for audio and filtering, PCB capacitance and load can alter real behavior. Keep the feedback loop compact, check capacitive-load stability, and use the shortest practical signal route from the source to the amplifier. Validate distortion, ringing, and gain error with the actual source impedance and termination.
