NE5534ADR2G - 13V/us Low-Noise Op Amp | onsemi | Audio
Teilenummer: NE5534ADR2G ✓ AktivNE5534ADR2G Übersicht
An operational amplifier is an analog integrated circuit that amplifies the voltage difference between its inverting and non-inverting inputs. The NE5534 family belongs to the broader hierarchy of operational amplifiers, analog amplifiers, linear ICs, and semiconductors. Its low-noise characteristics make it useful where small signals must be amplified without adding excessive broadband noise, while its relatively high slew rate supports audio-frequency waveforms and other signals that require faithful reproduction.
The NE5534ADR2G provides one amplifier circuit per package and operates across a 3 V to 20 V supply. According to the available product information, its slew rate is 13 V/us. Compared with amplifiers such as the TL083, the NE5534/5534A family is described as offering better noise performance, improved output-drive capability, and considerably higher small-signal and power bandwidths. These characteristics distinguish it from a basic precision-voltage amplifier intended primarily for instrumentation rather than audio bandwidth.
A single low-noise amplifier in an 8-SOIC package simplifies one-amplifier-per-board designs while preserving the pin arrangement associated with the NE5534 family. Tape-and-reel packaging supports automated assembly, while the commercial-temperature classification targets standard commercial equipment rather than an explicitly AEC-Q100-qualified automotive design. Availability, lifecycle status, and exact operating-temperature limits should therefore be confirmed against the current onsemi product documentation before production release.
Typical uses include microphone preamplification, audio mixer input stages, active equalization filters, musical-instrument signal conditioning, low-level sensor amplification, and test equipment. In each case, the amplifier should be supported by appropriate input and output impedance, power-supply bypassing, stable feedback compensation, and careful grounding. The broad supply range permits operation from single 5 V systems through higher-voltage analog rails, subject to the device-specific common-mode and output-swing limits.
The primary design consideration is stability. The amplifier must be used with feedback networks and load conditions compatible with its compensation, and decoupling capacitors should be placed close to the supply pins. Input bias-current error and source impedance can also dominate noise in high-impedance stages, making source resistance and grounding as important as the amplifier's headline noise rating.
This page consolidates the verified package, supply, slew-rate, amplifier-type, and sourcing information with application guidance, comparison parameters, and design cautions. It also distinguishes directly evidenced specifications from parameters that remain to be confirmed from the full manufacturer datasheet or current distributor inventory.

Typische Anwendungen
NE5534ADR2G ist geeignet für 6 Anwendungs: Low-Noise Audio Preamplifier, Audio Mixing Console Input, Active Equalization Filter, Musical Instrument Signal Conditioning, Precision Sensor Signal Conditioning, Test and Measurement Buffer.
Low-Noise Audio Preamplifier
The NE5534ADR2G fits low-level audio preamplification because it is a dedicated low-noise operational amplifier with a 13 V/us slew rate and improved output-drive capability. It can amplify microphone, line, or instrument signals before a volume control or mixer stage while preserving small-signal detail. The 3 V to 20 V supply range supports 5 V portable systems as well as higher-voltage analog rails. Designers should keep source impedances controlled, provide adequate supply bypassing, and reserve amplifier headroom because the available verified data does not quantify input noise voltage or exact small-signal bandwidth.
Empfohlen
Audio Mixing Console Input
NE5534ADR2G is applicable to an audio mixing-console input because one low-noise amplifier is provided in an 8-SOIC package and the family is described as having improved output drive compared with traditional TL083-type devices. A balanced or unbalanced input can be conditioned with feedback-defined gain before routing into a summing stage. The 13 V/us slew rate supports audio-rate waveforms, while the 3 V to 20 V supply flexibility permits use across compact and higher-voltage analog systems. Stable feedback design and adequate grounding are essential to prevent oscillation and preserve low-level channel performance.
Empfohlen
Active Equalization Filter
The NE5534ADR2G can implement an active bass, treble, or shelving filter where low noise and practical audio bandwidth are more important than minimal quiescent current. Its 13 V/us slew rate helps maintain low distortion for moderate-level signals, and the single-amplifier SOIC package allows each filter section to use a dedicated device. Component tolerances and the amplifier's exact gain-bandwidth value must be checked in the manufacturer datasheet before setting a high-Q corner. Standard unity-gain-stable compensation and conservative output loading are recommended during prototype validation.
Empfohlen
Musical Instrument Signal Conditioning
NE5534ADR2G is suitable for conditioning pickups and low-level instrument signals because low-noise amplification helps preserve quiet passages while the 13 V/us slew rate accommodates higher-level transients. It can serve as a preamp or active input buffer ahead of a mixing console or audio converter. The 3 V minimum supply is useful for compact battery-powered equipment, although designers should confirm output swing at the selected load. Input protection, phantom-power interaction, grounding, and decoupling must be considered because the supplied data does not specify maximum input voltage or common-mode range.
Empfohlen
Precision Sensor Signal Conditioning
NE5534ADR2G can amplify low-level outputs from sensors when the signal bandwidth remains compatible with the amplifier's small-signal bandwidth and output-drive limits. Its low-noise classification is valuable for strain, pressure, or position sensing, while the broad 3 V to 20 V supply range simplifies analog rail selection. Source resistance and input bias current must be evaluated because they can create offset or noise that dominates the sensor signal. The supplied excerpts do not provide input-offset voltage, bias current, or common-mode limits, so final sensor accuracy calculations require the full onsemi datasheet.
Empfohlen
Test and Measurement Buffer
NE5534ADR2G can serve as a buffer or gain stage in general-purpose test equipment when low-level signals require amplification without a dedicated instrumentation amplifier. The single-amplifier 8-SOIC arrangement provides a straightforward implementation for one channel, while the 13 V/us slew rate is useful for moderate-bandwidth waveforms. Designers must verify input bias-current error, input common-mode range, output swing, and stability with the intended source and load because those values are not quantified in the supplied excerpts. Low-noise grounding and short feedback paths are particularly important when the measured signal is small.

Designhinweise
Place the supply-bypass capacitor close to pins 4 and 7 and keep the return path short to the circuit ground reference. The verified 3 V to 20 V supply range is the total rail span, not permission to exceed either pin's voltage limits. Because the exact quiescent current and absolute maximum ratings are absent from the supplied excerpts, verify them in the manufacturer datasheet before estimating dissipation or selecting a bypass capacitor voltage rating.
Do not connect an external signal to pin 5 merely because it is adjacent to the negative supply in the SOIC outline. Pin 5 is the offset-null terminal, and the NE5534 single-amplifier pinout places the output at pin 6. Using the standard NE5534 socket pattern without checking the exact suffix and datasheet prevents confusion between the dual NE5532 and single NE5534 layouts, which can result in oscillation, incorrect output routing, or damage.
For low-level audio or sensor inputs, minimize source impedance and keep input traces away from the slew-rate-limiting output and supply paths. Use a stable feedback network and avoid excessive capacitive loading on pin 6. The verified data identifies low-noise operation and a 13 V/us slew rate but does not provide input bias current, noise density, or exact gain-bandwidth product, so those values should be obtained from the onsemi datasheet before setting gain, source resistance, or filter bandwidth.
Compliance-Informationen
The supplied excerpts identify a commercial-temperature NE5534ADR2G but do not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 information. AEC-Q100 is recorded as not applicable because this order code is identified as commercial-grade rather than an automotive-qualified variant.
