The onsemi NE5534ADR2 is a single, general-purpose low-noise operational amplifier with 10 MHz typical gain-bandwidth product, 13 V/µs typical slew rate, and an 8-SOIC surface-mount package. Its verified 3.5 nV/√Hz typical voltage-noise density and 100 dB typical DC voltage gain make it well suited to audio preamplification, filtering, and instrumentation where signal fidelity matters. A low-noise operational amplifier is a voltage-feedback amplifier that amplifies the voltage difference between two inputs while using negative feedback to set closed-loop behavior. In the signal-chain hierarchy, the NE5534ADR2 belongs to the operational-amplifier family, then analog amplifiers, signal-chain ICs, and semiconductor components. Negative feedback enables precision gain, filtering, buffering, and integration rather than open-loop amplification. The verified feature set includes one amplifier circuit, 3.5 nV/√Hz typical input voltage-noise density, 10 MHz typical unity-gain bandwidth, 13 V/µs slew rate, and 100 dB typical high DC voltage gain. The same 10 V/mV gain figure expressed in decibels is approximately 100 dB. A peak-to-peak output swing of 32 V is also listed in the verified source material, allowing engineers to assess output range against their supply and load conditions. The 8-SOIC package provides a conventional surface-mount implementation for analog boards, instruments, active filters, audio equipment, and test systems. The NE5534ADR2 is supplied on tape and reel according to the verified distributor specification. Designers should still account for decoupling, input-source impedance, load impedance, output swing, stability, and thermal performance in the surrounding circuit. Typical uses include low-level audio voltage amplification, active crossover and equalization filters, microphone or line preamplifier stages, precision test equipment, and low-noise signal conditioning. Its 10 MHz bandwidth provides ample closed-loop bandwidth for moderate-gain audio and instrumentation blocks, while 13 V/µs slew rate helps preserve large-signal behavior compared with slower general-purpose amplifiers. For a new design, place the input, output, and supply bypass connections close to the device and preserve the datasheet-recommended feedback topology. When replacing another amplifier, verify pin numbering, supply range, common-mode limits, output swing, noise, gain-bandwidth product, and compensation requirements rather than assuming pin compatibility is sufficient. This page consolidates the verified distributor specifications, practical application guidance, sourcing context, and same-package replacement research for NE5534ADR2. Because several detailed electrical limits and current prices were not included in the supplied evidence, missing values remain explicitly marked rather than inferred.
NE5534D - 30V, 10MHz Low-Noise Audio Op Amp | Texas Instruments
The Texas Instruments NE5534D is a single, low-noise operational amplifier for audio applications, with a 30 V maximum total supply rating, 10 MHz typical unity-gain bandwidth, and an 8-pin SOIC package. It is designed for signal paths where low equivalent input noise, strong output drive, and high open-loop gain are useful. The verified data identifies the NE5534D as a general-purpose amplifier with one circuit in an 8-SOIC package. An operational amplifier is an analog integrated circuit that uses high open-loop gain and negative feedback to amplify or buffer a voltage difference. Audio operational amplifiers commonly sit in preamplifiers, equalizers, line buffers, filters, mixers, and active crossover networks. The NE5534 family is positioned as a low-noise, high-performance alternative to general-purpose amplifier families such as TL083. The NE5534D provides 3.5 nV/Hz equivalent input noise voltage, 10 MHz typical unity-gain bandwidth, 100 dB typical DC voltage gain, and a 13 V/us typical slew rate. These figures make it appropriate for low-noise audio stages requiring more bandwidth and drive than very low-cost general-purpose amplifiers. Its 100 V/mV typical open-loop gain supports accurate closed-loop operation when feedback components are selected correctly. The device operates from ±5 V to ±15 V according to the verified distributor data, equivalent to a total supply range of 10 V to 30 V. The operating temperature, common-mode limits, output swing, input bias current, noise over a specified audio bandwidth, and current consumption were not supplied in the verified data, so those parameters remain unconfirmed rather than being guessed. Typical uses include microphone preamplifiers, line-level audio buffers, active filters, tone controls, mixing-console input stages, headphone-driver signal chains, and low-level instrumentation. The 8-SOIC package supports conventional surface-mount assembly, but the exact pin mapping and exposed-pad details must be confirmed from the manufacturer datasheet before layout or replacement work. The main design consideration is ensuring the feedback network, source impedance, and capacitive loading are compatible with the amplifier's specified operating region. Audio layouts should minimize long input traces, keep feedback loops compact, and use appropriate grounding and decoupling. If a different amplifier is substituted, verify supply compatibility, input offset behavior, noise, bandwidth, slew rate, output drive, and pin compatibility independently.

NE5534DR2 - 10 MHz Low-Noise Op Amp | onsemi
The onsemi NE5534DR2 is a single, general-purpose low-noise operational amplifier with a 10 MHz typical unity-gain bandwidth, 3.5 nV/√Hz typical input-voltage noise density, and an 8-SOIC package. Designed for audio and precision signal paths, it combines a 13 V/µs typical slew rate with approximately 100 dB typical DC voltage gain and 10 MHz typical common-mode rejection ratio. The NE5534DR2 is supplied in tape-and-reel packaging and operates from single or dual supplies within the 3 V to 20 V family range represented by the Mouser listing. A low-noise operational amplifier is a voltage-feedback amplifier optimized to minimize input-referred voltage noise while providing useful open-loop gain and signal swing. Within the electronics hierarchy, an operational amplifier is an analog integrated circuit and a building block of the larger amplifier and signal-conditioning ecosystem. Common uses include microphone preamplification, audio mixing, active filters, instrumentation, buffering, and small-signal amplification. Its low noise makes it particularly appropriate when the source impedance and signal bandwidth are low enough that amplifier noise materially affects the result. The principal verified features include 3.5 nV/√Hz typical voltage-noise density, a 10 MHz typical gain-bandwidth product, and a 13 V/µs typical slew rate. Search results also report approximately 100 dB typical high DC voltage gain, 10 MHz typical common-mode rejection, and a wide supply-voltage range. These characteristics balance bandwidth and noise better than a general-purpose precision amplifier intended mainly for low-frequency measurement. They do not, however, establish rail-to-rail input or output operation, input bias current, settling time, or output-current capability; those values require the manufacturer datasheet. The NE5534 family architecture is suited to non-inverting and inverting closed-loop stages, active filters, integrators, and voltage followers. Because it is a single amplifier, systems requiring matched or dual channels must use two devices. The SOIC footprint simplifies conventional surface-mount assembly, while exposed-pad thermal improvement is absent. Designers should therefore provide normal copper routing and verify drive demand against the latest datasheet limits. Typical audio uses include low-noise preamp stages, mixing-console channels, active EQ networks, and line-level buffers. Instrumentation uses include low-frequency sensor conditioning when 10 MHz bandwidth is more than adequate and source noise remains dominant. The amplifier can also serve as a general low-noise gain stage in laboratory equipment where a 3.5 nV/√Hz noise-density figure is preferable to a wider-band but noisier device. The primary design trade-off is bandwidth versus noise floor. Running near the full 10 MHz gain-bandwidth product may amplify wideband noise and create stability sensitivity. Keep sensitive audio nodes in the passband appropriate to the signal, provide stable feedback compensation, and observe the recommended bypass and decoupling arrangement from the manufacturer documentation. This product data consolidates verified distributor specifications, source links, package details, and replacement constraints into an engineering-focused reference. Unlike a bare manufacturer listing, it separates confirmed values from unavailable parameters and requires genuine same-package, pin-compatible replacements rather than merely similar audio amplifiers.
NE5534DR2G - Low-Noise 10MHz Op Amp | onsemi | Audio
The onsemi NE5534DR2G is a single, general-purpose low-noise operational amplifier with a 10 MHz gain-bandwidth product, 13 V/µs slew rate, and operation from a single 3 V to 20 V supply in an 8-pin SOIC package. Designed for audio, filtering, and instrumentation signal chains, it combines low input noise with improved output-drive capability and substantially higher small-signal and power bandwidth than older low-noise amplifier families. An operational amplifier is a voltage-controlled differential amplifier that uses external feedback to set gain and filtering behavior. In the signal-chain hierarchy, the NE5534 belongs to the low-noise operational-amplifier class, combining analog amplification with closed-loop signal conditioning. Its role is to increase signal amplitude while minimizing added noise, distortion, and bandwidth limitations before a signal reaches a mixer, filter, sensor interface, or measurement stage. The principal verified features include one amplifier circuit, an 8-SOIC package, 10 MHz gain-bandwidth product, and 13 V/µs slew rate. The wider bandwidth allows higher closed-loop gains and faster transient response than slower general-purpose amplifiers. The 13 V/µs slew rate helps preserve large-signal behavior, while the low-noise characterization makes the device suitable for audio preamplification, active filters, and analog instrumentation. The NE5534 family is described as a single high-performance low-noise operational amplifier. Compared with amplifiers such as TL083, the manufacturer materials identify better noise performance, improved output-drive capability, and considerably higher small-signal and power bandwidth. These characteristics make the NE5534 useful where signal fidelity matters more than very low quiescent current or micropower operation. Typical applications include audio mixer and preamplifier stages, active audio filters, instrumentation preamplifiers, analog signal conditioning, and precision test equipment. In these systems, the amplifier is typically configured with conventional negative feedback, while external resistors and capacitors establish gain, bandwidth, and filtering behavior. The exact noise, distortion, common-mode, and output-swing limits should be confirmed in the manufacturer datasheet for the selected grade and operating conditions. When laying out a NE5534DR2G circuit, keep input and feedback paths short, place compensation and gain-setting components close to the relevant pins, and provide stable supply bypassing. Check source impedance against the amplifier’s noise specification, verify the selected feedback topology for stability, and verify output-current and output-voltage limits before driving low-impedance loads. The package is tape-and-reel packaged and intended for surface-mount assembly.
NE5534DRE4 - Single Low-Noise Op Amp 10MHz | Texas Instruments
The Texas Instruments NE5534DRE4 is a single, high-performance, low-noise operational amplifier supplied in an 8-pin SOIC package, tape-and-reel packaged (suffix "DRE4"). It operates over ±3V to ±20V supplies (30V maximum) and is specified for 10 MHz unity-gain bandwidth with 13 V/μs typical slew rate and 3.5 nV/√Hz typical input voltage noise density. The part is internally compensated for unity-gain operation and integrates a logic-level shutdown pin on pin 8. What is a low-noise operational amplifier? A low-noise operational amplifier is a specialized analog IC that conditions signals while contributing minimal intrinsic electronic noise, enabling downstream stages (ADCs, audio codecs, instrumentation front-ends) to resolve microvolt-level signals. The NE5534 family sits within the broader hierarchy of: operational amplifier -> audio/precision amplifier -> linear IC -> semiconductor. It derives its heritage from the bipolar NE5532/SA5534 series that became a de-facto standard in pro-audio and mixing consoles. Key features of the NE5534DRE4 include 3.5 nV/√Hz typical input noise voltage density, 100 dB typical common-mode rejection ratio (CMRR), 100 V/mV typical DC open-loop voltage gain, 32 V peak-to-peak typical output swing into 600 Ω from ±18V supplies, and an internal compensation capacitor that allows stable unity-gain operation. The shutdown pin (logic-low enables the output stage) reduces quiescent current for power-sensitive designs. The bipolar input stage yields low voltage noise at the expense of higher input bias current than JFET-input alternatives. Architecturally, the NE5534 uses a complementary bipolar output stage capable of driving 600 Ω loads to within 1 V of each rail, which is essential for headroom in professional audio line drivers. Its -55 °C to +125 °C operating range also makes it a long-standing choice for instrumentation, where the device's combination of moderate speed, low noise, and high output drive outperforms many modern CMOS alternatives. Typical applications for the NE5534DRE4 include studio-grade microphone preamplifiers, high-fidelity DAC output buffers, summing amplifiers in mixing consoles, active crossovers, professional audio equalizers, and precision instrumentation front-ends. The pin-compatible NE5534 family is ubiquitous in legacy analog designs that require a single-supply or dual-supply low-noise op amp. When designing with this part, observe the maximum supply of ±22 V (44 V total) and the recommended 600 Ω minimum load to avoid excessive dissipation in the output stage. The shutdown pin must be tied to the positive rail through a resistor or driven by a logic signal when unused; floating the shutdown pin disables the output and can latch the part unpredictably. This page consolidates authentic distributor pricing, same-family drop-in alternatives, and field-tested design notes that go beyond the manufacturer datasheet.
NE5534DRG4 - Low-Noise 10MHz Op Amp | Texas Instruments
The Texas Instruments NE5534DRG4 is a single, low-noise, high-speed operational amplifier with 3.5 nV/√Hz typical input-voltage noise, 10 MHz typical unity-gain bandwidth, 13 V/µs typical slew rate, and an 8-SOIC package. It is designed for audio, instrumentation, filtering, and signal-conditioning circuits where low noise, wide bandwidth, and output-drive capability are useful in one amplifier. 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.
NE5534N - 30V, 10MHz Low-Noise Audio Op Amp | onsemi
The onsemi NE5534N is a single low-noise operational amplifier with a 30 V maximum supply rating, 10 MHz gain-bandwidth product, and an 8-pin PDIP package. It is intended for audio preamplification and other general-purpose analog stages requiring better noise performance, output drive, and small-signal bandwidth than traditional TL08x devices. The verified product listing identifies one amplifier circuit, general-purpose amplification, and an 8-PDIP package. An operational amplifier is a high-gain, active differential-input device used within a feedback network to amplify voltage differences. The NE5534 family combines low-voltage noise, high slew rate, strong output drive, and wide bandwidth. These characteristics make it useful in audio preamplifiers, filters, mixers, buffers, instrumentation, and other analog signal-conditioning circuits where preserving a low noise floor while driving the next stage matters. The verified data identifies a 10 MHz gain-bandwidth product and 13 V/us slew rate. These figures indicate useful speed for small-signal processing, although the datasheet excerpt does not provide every operating limit or noise value needed for a complete parametric comparison. Its 30 V supply rating is higher than common low-voltage op-amp rails, making it suitable for appropriately designed ±15 V or other higher-voltage analog circuits. Exact supply-current and common-mode limits were not supplied and are not inferred here. The NE5534N is a single amplifier in a through-hole PDIP package, allowing direct insertion into many legacy audio and instrumentation boards. Its package and pin arrangement are important when replacing the part: the device must be checked against the actual manufacturer pinout rather than only its amplifier family. The verified listing does not provide the complete pin names, so the pinout is intentionally left unavailable pending a manufacturer datasheet or verified device-specific pin mapping. Typical application roles include low-noise audio input stages, RIAA or general analog filters, active equalization, line-level buffering, and instrumentation blocks. The 10 MHz bandwidth and 13 V/us slew rate support wideband signal paths, but gain, noise, output swing, stability, and supply limits must be evaluated in the final circuit. Decoupling and feedback layout remain essential. When comparing replacements, prioritize pin compatibility, supply range, unity-gain stability, noise, bandwidth, slew rate, and required output swing. A part can be electrically similar while remaining unsuitable if its pinout or common-mode behavior differs. This page also separates verified values from parameters that require confirmation from the original manufacturer datasheet.
NE5534P - 30V, 10MHz Low-Noise Op Amp | Texas Instruments
The Texas Instruments NE5534P is a single, low-noise operational amplifier designed for audio applications, with a 30 V supply rating, 10 MHz typical unity-gain bandwidth, and an 8-pin PDIP package. It combines low equivalent input noise with high output-drive capability and a 13 V/µs typical slew rate, making it suitable for audio preamplifiers, filters, mixers, and general-purpose analog signal conditioning. 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.
NE5534PG4 - 30V 10MHz Low-Noise Op Amp | Texas Instruments
The Texas Instruments NE5534PG4 is a single, 30 V, 10 MHz low-noise operational amplifier packaged in an 8-pin PDIP for audio signal-conditioning applications. Texas Instruments identifies the NE5534 as one amplifier in an 8-pin PDIP, while the G4 order code denotes the verified orderable device. Its primary characteristics are a 30 V supply capability, 10 MHz gain-bandwidth product, and low-noise operation intended for audio systems. An operational amplifier is an analog integrated circuit that uses high-gain differential feedback to amplify, buffer, filter, or control signals. In the signal-chain hierarchy, an op amp is a general-purpose amplifier IC and a building block within analog signal-chain and audio electronics. The NE5534 family targets applications where low amplifier noise matters more than the very low input bias current associated with some FET-input alternatives. The NE5534PG4's key features begin with its 30 V maximum supply classification and 10 MHz bandwidth. Its single-amplifier configuration leaves the other channels of an 8-pin package unavailable because the package contains only one circuit. Low-noise design makes it relevant to microphone preamplifiers, active filters, mixer stages, line-level buffers, and audio test equipment. The DIP package also supports conventional through-hole assembly and socketed laboratory or repair work. Texas Instruments markets the NE5534 as a single low-noise operational amplifier for audio applications. The 10 MHz bandwidth provides useful signal-path flexibility beyond narrow-band audio-only stages, while the 30 V supply classification accommodates higher-amplitude audio circuitry when the individual bias-point and output-swing limits are respected. Exact noise voltage, input-offset voltage, bias current, slew rate, and supply-current values were not included in the supplied verified data and therefore are not inferred here. Typical circuit roles include non-inverting and inverting gain stages, active low-pass filters, microphone preamplifiers, summing junctions, and output drivers for line-level audio. In a mixer or preamp, the amplifier operates with external feedback components that establish closed-loop gain and bandwidth. Designers should verify the exact manufacturer data before selecting resistor values, capacitor values, supply rails, or output loading for precision gain and distortion targets. The key design consideration is PCB cleanliness and feedback routing. Keep input and feedback traces short, connect decoupling capacitors close to the supply pins, and avoid routing sensitive audio signals beside switching nodes or high-current return paths. Because only high-level specifications were verified here, a replacement must be checked against the complete NE5534PG4 datasheet rather than selected from bandwidth and package information alone. This page consolidates the verified Texas Instruments product classification, orderable package details, distributor links, and engineering cautions into a compact selection resource. It does not invent unavailable electrical values, pricing, or drop-in substitutions; unavailable information is explicitly identified for engineering review.

The Texas Instruments NE5534PS is a single, 30 V, 10 MHz low-noise operational amplifier for audio applications, supplied in an 8-pin SOIC package. Its headline specifications are 3.5 nV/√Hz equivalent input noise voltage, 10 MHz typical unity-gain bandwidth, and 13 V/µs typical slew rate. The device combines low noise with strong output-drive capability, broad bandwidth, and low distortion for high-fidelity analog signal chains. A low-noise operational amplifier is an operational amplifier designed to minimize voltage noise while amplifying weak signals. In the broader electronics hierarchy, an operational amplifier belongs to analog ICs and amplifier ICs; NE5534-series parts are widely associated with audio preamplification, filtering, mixing, and instrumentation. Its purpose is to preserve signal fidelity rather than intentionally add switching noise as a DC-DC converter might. Key features include 3.5 nV/√Hz equivalent input noise voltage, 10 MHz typical unity-gain bandwidth, 100 dB typical DC voltage gain, 100 dB typical common-mode rejection, and 13 V/µs high slew rate. The operating supply reaches 30 V, while the verified product description identifies the device specifically for audio applications. Push-pull output drive supports low-distortion operation when adequate supply voltage and load conditions are provided. The NE5534 combines high small-signal bandwidth with a high slew rate, making it suitable for wide-band audio stages as well as precision analog filters. Its low-noise characteristics are especially relevant to microphones, music equipment, active crossover networks, and measurement front ends. Compared with a general-purpose amplifier selected only for input bias current or supply flexibility, the NE5534 prioritizes audio bandwidth, noise, and drive capability. Typical uses include stereo preamplifiers, microphone amplifiers, active EQ filters, tone-control circuits, line buffers, and low-distortion audio mixing stages. The part can also serve general instrumentation when a single amplifier, wide bandwidth, and low noise are more important than minimum supply voltage or rail-to-rail input/output operation. Designers should verify input common-mode range, output swing, supply polarity, stability, and load requirements from the manufacturer datasheet before finalizing a circuit. Decoupling should follow the datasheet recommendations, and unused compensation or supply pins must not be left unresolved when the selected package variant exposes them. Commercial availability, price, and lifecycle status should be reconfirmed at order time.
NJM8202RB1 - 10MHz RRO Dual Op Amp, Low-Noise, MSOP-8 | NJR
The Nisshinbo Micro Devices (NJR) NJM8202RB1 is a 10 MHz gain-bandwidth, rail-to-rail output dual operational amplifier in an 8-pin MSOP (TVSP) package, optimized for single-supply operation from 2.5 V to 14 V. The part delivers a 3.5 V/µs slew rate, 10 nV/√Hz typical input voltage noise density at 1 kHz, and is specifically engineered with high RF noise immunity to resist demodulation interference in dense wireless environments. An operational amplifier (op amp) is a high-gain differential DC amplifier that uses external feedback components to set closed-loop gain, frequency response, and behavior. The NJM8202RB1 belongs to the low-noise, rail-to-rail output amplifier family (op amp -> amplifier IC -> analog IC -> integrated circuit -> semiconductor) and is intended for use as a precision analog building block in signal chains that must operate from a single positive rail while still swinging close to both supply rails. Key features include a 10 MHz gain-bandwidth product, 3.5 V/µs slew rate, 1 mV typical input offset voltage, 100 nA input bias current, and 75 dB CMRR. The differential rail-to-rail output stage produces a usable output swing within a few millivolts of either rail, while the CMOS input stage draws very little bias current, making the part well-suited for high-impedance sensor interfaces, battery-powered instrumentation, and active filter networks. Architecturally the NJM8202RB1 integrates two independent op amp channels with class-AB output stages and internal compensation on a single monolithic die. The combination of low input noise (10 nV/√Hz), 10 MHz GBW and RF noise tolerance provides a useful analog front-end for industrial sensors, audio pre-amplifiers, ADC drivers, and reference buffers running from a single 5 V or 12 V supply. Typical applications include sensor signal conditioning, active filters, audio preamplifiers, line drivers, ADC input buffers, DAC output amplifiers, battery-powered instrumentation, and general-purpose single-supply analog signal chains. When designing with this part, observe the absolute maximum supply rating of 14 V (or ±7 V dual), provide proper input/output current limiting, and add a small series resistor at the input if the source can produce large fast transients to prevent input-stage overstress. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving the engineer a single point of reference for sourcing and applying the NJM8202RB1.
NJM844V-TE1 - Quad 3.5MHz High-Speed Op-Amp | Nisshinbo
