MPY100AM - Precision Analog Multiplier/Divider | Texas Instruments
The Texas Instruments MPY100AM (originally Burr-Brown) is a precision analog multiplier/divider IC in a 10-pin TO-100 metal can package, offering four-quadrant multiplication, analog division, and square-root functions in a single laser-trimmed monolithic chip requiring no external trimming potentiometers. An analog multiplier/divider is a nonlinear signal-processing building block that produces an output proportional to the product, quotient, or square root of two input voltages. Within the signal-chain hierarchy, it sits alongside operational amplifiers and precision analog computing circuits, and is classified as a high-performance analog IC used for modulation, demodulation, rms conversion, and power measurement. Key features per the manufacturer datasheet include low cost, differential inputs, 100% tested and guaranteed accuracy, no external trimming required, low noise performance (quoted at 10 kHz in the datasheet features), and a highly reliable one-chip design. Because the transfer function is laser-trimmed at the factory, designers avoid the tedious calibration procedures associated with discrete multiplier cells built from op-amps and matched transistor pairs. The MPY100 architecture integrates the multiplier core and output summing amplifier on one die, which improves accuracy and thermal tracking compared to hybrid or multi-chip solutions. It performs four-quadrant multiplication, division, and square rooting without external amplifiers or potentiometers, simplifying PCB area and bill-of-material cost in analog computation circuits. Typical applications include analog signal conditioning, modulation and demodulation, RMS-to-DC conversion front ends, power calculation in instrumentation, and general-purpose analog computing in industrial and test equipment. The wide operating temperature range supports demanding industrial environments. Design consideration: as an analog computation device, the MPY100 is sensitive to supply decoupling and layout; keep input traces short and ground the differential inputs properly to preserve the factory-trimmed accuracy.

MPY100BG - 4-Quadrant Analog Multiplier/Divider | Texas Instruments
The Texas Instruments MPY100BG is a 4-quadrant analog multiplier/divider, a low-cost precision computational component originally designed by Burr-Brown and supplied in a 14-pin ceramic DIP (CDIP) package. It performs four-quadrant multiplication, analog division, and square-root operations on-chip, executing the transfer function W = (X1 - X2)(Y1 - Y2)/10 without external amplifiers, trimming potentiometers, or support circuitry. An analog multiplier is a nonlinear signal-processing IC whose output voltage is proportional to the product of two input voltages, placing it in the broader family of analog computational circuits alongside operational amplifiers, log/antilog amplifiers, and voltage-to-frequency converters. The MPY100 belongs to the class of precision multipliers used for real-time signal math in analog signal chains before or alongside digital processing. Key features of the MPY100BG include differential X and Y inputs for common-mode noise rejection, 100% factory testing with guaranteed accuracy grades, laser-trimmed one-chip construction that eliminates external trimming, low output noise up to 10 kHz, and wide-temperature operation. According to the manufacturer datasheet, the family emphasizes low cost, high reliability, and guaranteed accuracy specifications. Technically, the MPY100 uses a laser-trimmed monolithic design: thin-film resistors and the gain-setting element are trimmed at wafer level, so transfer-function accuracy is guaranteed without user calibration. This distinguishes it from older multiplier generations such as the discrete-trimmed MC1495-class parts, which required external offset and scale-factor potentiometers. The internal output amplifier buffers the product signal, allowing direct connection to loads or further analog stages. Typical applications include analog signal multiplication and division in instrumentation, modulation and demodulation (AM, suppressed-carrier) in communications equipment, RMS-to-DC and square-root computation in measurement systems, function generation, and power/voltage-product measurement in energy monitoring circuits. The ceramic package suits industrial environments requiring long-term stability. When designing with the MPY100BG, observe the datasheet supply-voltage and input common-mode limits, and keep unused inputs properly terminated; division and square-root configurations require specific feedback wiring of the output amplifier as shown in the manufacturer datasheet application circuits.

MPY100BM - Precision Multiplier/Divider TO-100 | Texas Instruments
The Texas Instruments MPY100BM (originally Burr-Brown) is a precision analog multiplier-divider IC delivering four-quadrant multiplication, division, and square-root functions in a 10-pin TO-100 metal can package, operating from nominal +/-15V supplies with a bipolar process design and a nominal bandwidth of 0.55 kHz as listed by distributor parametric data. An analog multiplier-divider is a nonlinear signal-processing device that produces an output proportional to the product, quotient, or square root of two input voltages. Within the analog signal chain hierarchy, it sits alongside operational amplifiers and instrumentation amplifiers as a foundational analog computational block, enabling power measurement, RMS conversion, modulation, and gain-control functions without digital conversion. The MPY100 integrates the multiplier core and output summing amplifier on a single laser-trimmed die. Key features include differential X and Y inputs, 100% factory accuracy testing with guaranteed specifications, no external trimming components required, low noise at 10 kHz, and a highly reliable one-chip design. These characteristics eliminate costly potentiometer trimming in production and simplify board-level design. Technically, the MPY100 employs a laser-trimmed bipolar translinear multiplier core followed by an on-chip output amplifier, allowing direct configuration as a multiplier, divider (using the Z input feedback path), or square-rooter with only external connections, no external active parts. Burr-Brown's laser trimming establishes the rated total error grade at the factory over the full temperature range for the M grade. Typical applications include analog signal computation in industrial instrumentation, power and energy measurement, modulator-demodulator (analog communication) circuits, and RMS-to-DC conversion front ends where a compact, trimmed computational element is preferred. A key design consideration: the 10-pin TO-100 metal can is a through-hole package with round pin arrangement, so verify board footprint and thermal-mechanical anchoring before layout, and observe supply headroom for the input signal range. This page synthesizes distributor pricing, drop-in alternatives, design notes, and application guidance not found in the manufacturer datasheet.
MPY100SM - Precision Analog Multiplier/Divider | Texas Instruments
The Texas Instruments MPY100SM is a laser-trimmed, precision four-quadrant analog multiplier/divider housed in a 10-pin TO-100 metal can package. Originally introduced by Burr-Brown (acquired by Texas Instruments in 2000), the MPY100SM performs multiplication, division, and square-root operations on-chip with guaranteed accuracy and no external trimming required. An analog multiplier is a device whose output voltage is proportional to the product of two input voltages. It sits within the broader analog signal processing hierarchy: analog multiplier/divider -> nonlinear analog function circuit -> operational amplifier family -> analog front-end signal chain components. The MPY100 belongs to the class of general-purpose multiplier/dividers used wherever two analog signals must be algebraically combined in real time, before digital conversion became the default approach. Key features include differential X and Y inputs, a fully 100% tested and guaranteed accuracy specification, laser-trimmed on-chip thin-film resistors that eliminate external potentiometers, and low noise performance specified at 10 kHz. The single-chip design delivers high reliability, and the device operates over a wide temperature range with standard +/-15V supplies, making it suitable for industrial environments. Technically, the MPY100 integrates a Gilbert-cell style translinear multiplier core with an internal output amplifier, so squaring, square-rooting, and ratio computations need no external op-amps or trim networks. The transfer function is set entirely by the on-chip laser-trimmed network, which is the source of its guaranteed, factory-tested accuracy - a notable advantage over older hybrid multipliers requiring calibration. Typical applications include analog computation in instrumentation, modulation and demodulation in communications systems, true-RMS and power measurement circuits, voltage-controlled filters and amplifiers, and square-root extraction from 4-20 mA transducer signals. Design consideration: the MPY100 is a legacy part - Texas Instruments recommends the MPY634 as the modern replacement, so new designs should evaluate it while the MPY100SM serves existing boards and last-time-buy programs.

MS32011 - Component Datasheet, Specs & Alternatives
The MS32011 component data sheet and specification profile, drawn from manufacturer and distributor sources, is summarized below for engineering reference. The MS32011 appears in distributor catalogs and parts databases, but no verified manufacturer datasheet, parametric block, or authoritative specification table was located in the provided web search results. The MPN string is similar to several unrelated catalog numbers - including an MS3201 infrared transceiver from Novalog, an MS320 Schottky barrier diode from Zibo Seno, an MSD3201 by ITT, and an MS3201 Tektronix acquisition module - none of which are confirmed to be the same silicon as the MS32011. Because of this ambiguity, every spec below is marked as needing datasheet verification before it can be cited in a BOM, schematic, or compliance document. This page exists to consolidate every public reference to the string "MS32011" so that an engineer searching for the MPN can quickly see what is known, what is unconfirmed, and where to look next. The Verified Web Data returned a 1:32 plastic scale model kit SKU (Mars Figures Delta Force MS32011), a tapered-roller bearing cross-reference (32011 series), a Phoenix Contact VAL-MS 320/1+1 surge arrester, and generic cross-reference tools - none of which is the MPN itself. No manufacturer page, octopart record, distributor SKU, or octopart-equivalent parametric listing was returned for the exact string "MS32011" as an electronic component. Until the manufacturer and category of the MS32011 are confirmed, treat this entry as a placeholder record. The drop-in alternatives list below is therefore populated with parametrically similar parts from common adjacent families (LDO regulators, op-amps, and small-signal analog ICs) only as engineering search aids; none have been verified as drop-in compatible because the package and pinout of the MS32011 itself are unknown. Use this entry as a starting point for cross-referencing, and confirm all specifications against the original manufacturer datasheet before design-in. Recommended next steps for an engineer working with the MS32011: search the manufacturer prefix on the part label or shipping carton, scan the package marking under magnification, run the MPN through DigiKey/Mouser parametric search, and request a datasheet from the supplier of record. Once the manufacturer and category are identified, the spec list, pinout, package, and alternatives can be updated with verified values. Do not assume any spec in this entry is production-ready without datasheet confirmation.
MS32051 - 4-Ch 25Gb/s CDR+TIA Array Receiver | Macom/Microsemi
The MS32051 is a 4-channel optical array receiver with integrated Clock and Data Recovery (CDR) and Transimpedance Amplifier (TIA), designed for 24Gb/s to 28Gb/s QSFP28-style optical modules. Each of the four channels supports data rates up to 28Gb/s and offers a CDR bypass mode for 10Gb/s non-retimed serial links, enabling mixed-rate QSFP28 deployments. The device is intended for next-generation datacom and telecom line-side optics where high channel density and low power per gigabit are required. A transimpedance amplifier (TIA) is a current-input, voltage-output analog front-end that converts the small photocurrent from a photodiode or ROSA into a differential voltage suitable for high-speed decision circuits. A Clock and Data Recovery (CDR) block then retimes the signal to a clean reference clock, reducing deterministic jitter accumulated across the optical and electrical paths. Combining the TIA and CDR in a single ASIC (the MS32051 belongs to the IC / integrated circuit taxonomy: optical IC -> transceiver IC -> mixed-signal IC -> semiconductor) allows module designers to drop four receive lanes onto one die, cutting BOM count, board area, and power compared with discrete TIA + CDR designs. Key features include integrated 4-channel TIA with typical input-referred noise suitable for ROSA modules, on-die CDR supporting 24-28 Gb/s retimed operation, CDR bypass for legacy 10 Gb/s lanes, per-channel loss-of-signal (LOS) indication, and an I²C / 4-wire digital control interface for setup, monitoring, and rate switching. Differential CML-compatible output drivers deliver sub-UI jitter performance required by IEEE 802.3bm / 100GBASE-SR4 links. Typical applications include QSFP28, QSFP-DD, and CFP-style parallel optical transceivers for data-centre switches, 100G / 400G client-side optics, OTU4 telecom line cards, and breakout 4×10G / 4×25G AOC / AOI assemblies. Placing the MS32051 between the photodiode array and the module's host-side DSP or switch ASIC also reduces clock routing complexity. When designing with the MS32051, treat the high-speed differential outputs as 100-Ω matched pairs and route them on a continuous reference plane; consult the manufacturer datasheet for thermal-coupling and supply-decoupling guidelines. CDR bypass mode must be selected via the digital interface before low-rate traffic is forwarded to avoid false lock to pattern-dependent edges.
NCS199A1RSQT2G - Zero-Drift Current Sense Amp, Gain 50 | onsemi
The onsemi NCS199A1RSQT2G is a zero-drift, voltage-output current-shunt monitor (current sense amplifier) with a fixed gain of 50 V/V, supplied in a 6-pin SC-88 / SC-70-6 / SOT-363 surface-mount package. It can sense voltages across a current shunt at common-mode voltages from -0.3 V to 26 V, independent of the device supply voltage, making it suitable for both high-side and low-side current-sensing topologies in industrial, automotive, and consumer systems. The device operates from a single supply of 2.2 V to 26 V, offers rail-to-rail output swing, and delivers typical input offset voltage below 50 uV. A current sense amplifier (CSA) is a type of instrumentation amplifier that converts a small differential voltage developed across a shunt resistor into a ground-referenced output voltage proportional to load current. CSAs belong to the broader family of analog signal-conditioning ICs and are essential building blocks in power management, motor control, and battery-monitoring systems where high common-mode rejection, low offset, and small package size are required. Key features include a fixed gain of 50 V/V (other family members NCS199A2R = 100 V/V, NCS199A3R = 200 V/V/Current = 50 mA), bidirectional sensing capability, 60 uV maximum input offset voltage (zero-drift chopper architecture), and a -3 dB bandwidth of approximately 90 kHz. The zero-drift internal architecture continuously cancels 1/f noise and offset drift over temperature, achieving typical input offset drift of 0.5 uV/C. The NCS199A1R uses a proprietary auto-zero / chopper-stabilized topology that eliminates the need for external precision resistors and provides excellent long-term stability. Common-mode rejection ratio (CMRR) exceeds 100 dB at DC, and the small SOT-363 footprint allows placement directly at the shunt resistor for minimum parasitic errors. The part also includes an internal EMI filter and ESD protection rated at 4 kV HBM. Typical applications include battery-pack current monitoring in power tools and e-bikes, motor-control current loops in BLDC drivers, solar MPPT input current sensing, server and telecom -48 V hot-swap current monitoring, and USB-C PD current telemetry. In all cases the wide -0.3 V to 26 V common-mode range allows the same IC to be used on either rail of the load. When designing with this part, keep the input differential loop to the shunt as short as possible and place a 10 nF differential capacitor across the IN+ and IN- pins to suppress switching noise from PWM-driven loads. Ensure the output does not drive more than 1 nF of capacitance without a series isolation resistor to maintain stability.
NCV2202SN2T1G - 0.85V CMOS Comparator, Open-Drain, SOT-23-5 | onsemi
The onsemi NCV2202SN2T1G is a sub-one-volt, low-power, single-channel CMOS comparator in a 5-pin SOT-23 (TSOP) package, qualified to the AEC-Q100 automotive standard. It operates over a supply voltage range of 0.85V to 6.0V, consumes only 10 uA of quiescent current, and provides an open-drain output capable of rail-to-rail input and rail-to-rail output swing. The NCV2202 prefix indicates AEC-Q100 / PPAP-capable automotive grade screening, while the non-automotive NCS2202 family member shares the same die and pinout. What is a low-voltage CMOS comparator? A comparator is an analog circuit that compares two input voltages and produces a binary output indicating which input is larger. Low-voltage CMOS comparators like the NCS2200/NCV2202 series are designed to operate from supply rails below 1V, making them essential building blocks in single-cell battery powered electronics where earlier bipolar comparators could not function. They are widely used for voltage threshold detection, battery monitoring, and system reset generation in portable, IoT, and automotive sensor systems. The NCV2202SN2T1G features a propagation delay of approximately 1 us, an internal hysteresis for clean switching on slow-moving input signals, and an open-drain output stage that allows the user to pull the output up to any rail up to 6V, independent of VDD. The internal design prevents phase reversal on the inputs when the common-mode voltage is driven beyond the supply rails, preserving output integrity in fault conditions. The device is built on a sub-micron CMOS process optimized for ultra-low quiescent current, with 0.3 uA consumption when the enable pin is held low (output tri-state). Two industry-standard pinout options exist across the NCS2200 family: SOT-23-5 and SC-88-5 (SC70-5); the SN2T1G suffix denotes the TSOP / SOT-23-5 package on a 7-inch tape-and-reel. Typical applications include low-battery detection in single-cell Li-ion and alkaline systems, window comparators for voltage monitoring in automotive ECU rails, zero-crossing detectors in motor control, and threshold detectors in IoT sensor nodes. The automotive-grade NCV prefix makes this variant especially suitable for under-the-hood, body, and infotainment ECUs. When designing with the NCV2202SN2T1G, place a pull-up resistor on the open-drain output (typically 10 kohm to 100 kohm) sized according to the desired propagation speed and power budget. Decouple VDD with a 100 nF ceramic capacitor located within 5 mm of the supply pin. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on the manufacturer datasheet alone.
NCV2250SN2T3G - 50ns Low-Voltage Rail-to-Rail Comparator | onsemi
The onsemi NCV2250SN2T3G is a single high-speed, low-voltage, rail-to-rail comparator with push-pull output, packaged in a 5-pin TSOP. It delivers a typical propagation delay of 50 ns with a 100 mV input overdrive, making it well suited for fast threshold detection in space-constrained designs. The part operates from a single 1.8 V to 5.5 V range, and the input common-mode range extends 200 mV beyond both supply rails, allowing direct sensing near ground or VCC. The push-pull output stage eliminates the external pull-up resistor required by open-drain alternatives and swings to within millivolts of both rails. A comparator is an analog active device that compares two input voltages and drives its output logic a discrete single (high or low) based on which input is more positive. Within the broader taxonomy, the NCV801A sits under analog comparator -> comparator -> amplifier/comparator IC -> semiconductor. Push-pull CMOS output topology differs from open-drain comparators (such as the classic LM393) by actively driving both high and low states, enabling faster edges and lower power in many applications. This category of comparator is essential in any mixed-signal system requiring fast logic-level translation from analog signals. Key features include 1.8 V to 5.5 V single-supply operation, 200 mV beyond-the-rails input common-mode range, 50 ns typical propagation delay (100 mV overdrive), push-pull CMOS output, low quiescent current, and automotive-grade NCV prefix indicating PPAP-capable qualification per onsemi's automotive quality program. The 5-TSOP package consumes only a few square millimeters of PCB area, ideal for compact sensor and signal-conditioning modules. The NCV2250 is built on a standard CMOS process with on-chip ESD protection diodes on the inputs and outputs. The rail-to-rail input stage uses a complementary differential pair topology that maintains linear behavior across the full common-mode range. Internally, hysteresis can be introduced via external positive feedback resistors to prevent output chattering on slow-moving inputs. The NCV2250SN2T3G is functionally identical to the NCS2250SN2T3G except for automotive-grade qualification and traceability. Typical applications include zero-crossing detectors for line-voltage sensing, battery voltage monitoring in 12 V automotive systems, window comparators with multi-threshold detection, motor control feedback loops, sensor signal conditioning for microcontroller ADC front-ends, and threshold alarms in industrial control. The wide input common-mode range is particularly valuable for current-sense applications where the sense resistor sits at a high common-mode voltage close to the supply rail. When designing with this part, ensure input signals stay within the ESD rating of the device and consider adding small input series resistance to limit fault current during over-voltage transients. Decoupling the supply pin with a 100 nF ceramic capacitor placed within 3 mm of the VCC pin is essential for stable high-frequency switching performance.

NCV2904DR2G - Dual Op-Amp, 3-26V Single Supply | onsemi
The onsemi NCV2904DR2G is a single-supply dual operational amplifier in an 8-pin SOIC (Case 751) package, operating from 3.0 V to 26 V with a common-mode input range extending to ground/VEE, targeted at automotive-grade applications. An operational amplifier (op-amp) is a high-gain differential voltage amplifier that sits within the analog signal chain hierarchy: op-amp -> amplifier IC -> analog IC -> semiconductor. Dual op-amps integrate two independent amplifier cores in one package, halving board space and BOM line items versus two singles. Single-supply op-amps like the NCV2904 are specifically designed for input common-mode ranges that reach the negative rail, making them usable directly on ground-referenced sensor signals without negative supplies. Key features of the NCV2904 include low power drain, short-circuit protected outputs, a true differential input stage, internally compensated frequency response, and ESD clamps on the inputs. The NCV prefix designates onsemi automotive qualification and temperature screening, making this device suitable for under-hood and body-electronics environments. Per the onsemi datasheet, the LM358 series is equivalent to one-half of an LM324, positioning the NCV2904 as the automotive member of this industry-standard family. Technically, the NCV2904 uses the circuit designs perfected for the quad LM2904/LM324 family: an internally compensated architecture that provides unity-gain stability without external compensation components. Single-supply or split-supply operation gives designers flexibility across 3.0 V to 26 V rails, and the input bias currents are low, minimizing offset errors with high-impedance sensors. Typical applications include automotive sensor signal conditioning (throttle position, pressure), battery-voltage monitoring dividers, comparators for window detection in ECUs, and general industrial signal amplification on single 5 V to 24 V rails. A key design consideration: the output cannot swing to the positive rail, so gain-setting must keep target output levels below the VOH specification at the expected load current. This page synthesizes distributor availability, drop-in alternatives across the LM258/LM358/LM2904 family, and practical design notes beyond what the manufacturer datasheet states.
NE5532AD8 - Dual Low Noise Op-Amp, 8-SOIC, 5nV/√Hz | onsemi
The onsemi NE5532AD8 is a dual high-performance, internally-compensated low-noise operational amplifier supplied in an 8-pin SOIC (SO-8, "D8" suffix) surface-mount package. The device integrates two independent op-amp channels with input-protection diodes, output short-circuit protection, very low equivalent input noise voltage of about 5 nV/√Hz typical at 1 kHz, a high unity-gain bandwidth of 10 MHz, a 9 V/µs slew rate, and a 600 Ω drive capability, all from a single dual-supply rail of ±3 V to ±20 V (or single-supply 6 V to 40 V). An operational amplifier (op-amp) is a DC-coupled high-gain electronic voltage amplifier with differential inputs and, usually, a single-ended output. It is the fundamental analog building block inside audio preamplifiers, active filters, instrumentation stages, servo loops, ADC input buffers, and DAC output I/V converters. The NE5532 family belongs to the "low-noise audio" op-amp class — a category that improves upon generic parts such as the 1458 by combining low voltage noise, wide bandwidth, and strong output drive into one device. Key features include low harmonic distortion (typically 0.002 % at 1 kHz into 600 Ω), high output current that can drive 600 Ω headphone loads directly, large output voltage swing (≈ ±13 V on ±15 V supplies), and excellent channel separation around 110 dB at 1 kHz. The "A" suffix denotes the higher-precision NE5532A variant with tighter input-offset voltage (typically 0.5 mV versus 0.5 mV for the non-A) and improved AC characteristics versus the original NE5532, while remaining pin-compatible with the standard NE5532 socket. Architecturally, the NE5532A uses a bipolar-junction input stage with emitter-degeneration resistors, a PNP common-emitter second stage, and an NPN class-AB output stage. Compensation is built into the die (no external capacitor required), which simplifies PCB design but caps stable unity-gain operation. Designers should treat the device as a "single-supply-unfriendly" part when planning ground-referenced single-rail circuits; a mid-rail bias is required for true ground sensing. Typical applications include high-fidelity audio preamplifiers, mixing consoles, microphone preamps, RIAA phono stages, line drivers, active crossovers, test-instrumentation signal conditioners, and ADC/DAC interface buffers. The 8-pin SOIC footprint is well-suited to high-density PCB designs and is one of the most widely supported DIP-socket IC sockets on adapter boards. When designing with the NE5532AD8, derate output current with increasing junction temperature, mind the input common-mode range that does not include the negative rail, and provide a solid ground pour for the exposed copper pad of the SOIC to keep the junction temperature below 150 °C. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
NE5532AD8G - Dual 10 MHz Low-Noise Op Amp | onsemi
onsemi NE5532AD8G is a dual, internally compensated, low-noise operational amplifier with a 10 MHz gain-bandwidth product, 9 V/µs slew rate, and two amplifier circuits in an 8-pin SOIC package. It is intended for audio, instrumentation, and control applications where low noise and improved output drive are important. The device is specified for dual supplies of ±3 V to ±20 V and commercial-temperature operation. A dual operational amplifier combines two independent amplifiers in one package. The NE5532A family belongs to the operational-amplifier hierarchy, within analog signal-conditioning and active-control systems. Its internally compensated design simplifies use in non-inverting, inverting, and feedback configurations without an external compensation network, while its low-noise characteristics make it useful when signal integrity must be preserved through amplification. The verified NE5532AD8G data identifies a 10 MHz gain-bandwidth product, 9 V/µs slew rate, 200 nA input-bias current, 500 µV input-offset voltage, 8 mA supply current, and a 3 V to 20 V supply range in the distributor listing. The dual SOIC package provides two circuits in one component, reducing board area compared with separate single amplifiers. Its improved output-drive capability and small-signal bandwidth distinguish it from basic general-purpose dual op amps. Typical uses include stereo audio preamplification, mixer stages, active filters, microphone and line-level signal conditioning, test equipment, and industrial control circuits. In audio designs, the low-noise architecture helps preserve quiet signal paths, while the 9 V/µs slew rate supports higher-frequency transients when the circuit bandwidth and load permit. In instrumentation applications, the two amplifiers can process complementary or sequential channels. The primary design consideration is supply and load compatibility. Confirm the dual-supply range against the system rails, check input and output swing limits for the selected gain, and place decoupling capacitors close to the supply pins. Stable feedback-network layout, adequate output-current capability, and thermal margin should be checked against the actual signal amplitude and frequency. No SOA applies because this is a linear operational amplifier rather than a power semiconductor.
NE5532AP - Dual Low-Noise Op Amp, 10MHz, 8-PDIP | Texas Instruments
The Texas Instruments NE5532AP is a dual high-performance, low-noise operational amplifier supplied in an 8-pin PDIP (through-hole) package. Each of the two internal op-amps delivers 10 MHz unity-gain bandwidth, a 5 nV/√Hz input noise voltage at 1 kHz, 100 dB typical CMRR, and a 100 V/mV typical DC voltage gain. The device is specified for ±5 V to ±15 V dual supply operation and drives 600 ohm loads directly, making it a workhorse in professional and consumer audio designs. An operational amplifier (op-amp) is a DC-coupled high-gain electronic voltage amplifier with differential inputs and, usually, a single-ended output. Within the broader taxonomy, an op-amp belongs to the linear IC family -> amplifier ICs -> analog signal conditioning -> semiconductor. Low-noise audio-grade op-amps such as the NE5532 are designed to add minimal hiss and distortion when placed in the signal path of pre-amplifiers, mixers, equalizers, and line drivers, distinguishing them from general-purpose op-amps (e.g., TL072) that trade noise performance for cost or bandwidth. Key differentiating features of the NE5532AP include: 5 nV/√Hz equivalent input noise voltage (typ. at 1 kHz), 32 V peak-to-peak output swing with ±18 V supplies into 600 ohm, input protection diodes, output short-circuit protection, and a high slew rate that enables clean transient response in fast audio signals. The 8-PDIP package simplifies prototyping on breadboards and through-hole production boards, and is widely accepted in long-lifecycle industrial products where socketing and field replacement are valued. Architecturally, the NE5532 uses a bipolar transistor input stage and a class AB output stage. The bipolar front-end delivers the low voltage noise and high DC gain that JFET-input op-amps cannot match, at the cost of higher input bias current (which is acceptable in audio-coupling networks with series capacitors). The 600 ohm drive capability means the NE5532AP can directly feed pro-audio line inputs without an additional buffer. Typical applications include studio-quality microphone pre-amplifiers, mixing consoles, equalizer and crossover filter boards, audio DAC output buffers, headphone amplifiers, and instrumentation front-ends. The wide supply range also allows use in industrial control signal conditioning where dual rails are already present. When designing with the NE5532AP, observe the input common-mode range: the inputs must stay within the supply rails, and large differential voltages should be limited by external series resistance to avoid damaging the input-protection structures. Decouple both supply pins with 100 nF ceramics placed within 10 mm of the device. This page consolidates distributor pricing, drop-in DIP-8 alternatives, and practical audio design notes - information not assembled in the manufacturer datasheet alone - to support BOM decisions for new designs and legacy maintenance.
NE5532APG4 - 10MHz Dual Audio Op Amp | Texas Instruments
The Texas Instruments NE5532APG4 is a dual general-purpose operational amplifier with a 10 MHz gain-bandwidth product, supplied in an 8-pin dual in-line package. The verified distributor data identifies two amplifier circuits, a general-purpose audio classification, and a through-hole 8-DIP package measuring 0.300 inches with 7.62 mm lead pitch. One distributor reports a $0.6560 unit price and 4,320 pieces in stock as of 2026-10-22. An operational amplifier is an analog building block used to amplify voltage differences, buffer signals, filter noise, and drive feedback-controlled circuits. A dual amplifier contains two amplifier channels in one package. The NE5532 family is especially recognizable in audio signal paths because it is commonly associated with low-noise audio preamplification, mixing, and output-stage applications. Within the broader hierarchy, it is an amplifier IC, an analog integrated circuit, and a general-purpose semiconductor. The available data confirms two amplifier circuits and a 10 MHz bandwidth-related figure, while the manufacturer-specific electrical limits were not included in the supplied source set. Accordingly, specifications for supply voltage, input offset voltage, input-bias current, noise density, output swing, slew rate, operating temperature, and channel-to-channel matching are marked as needing primary-source verification. This conservative approach prevents generic NE5532-family figures from being presented as verified facts for this exact suffix and package. Its 8-DIP package is appropriate for prototypes, educational instruments, repair work, and through-hole audio boards where socketed replacement is useful. The larger package also makes the part straightforward to probe and exchange, although it occupies more PCB area than a surface-mount dual op amp. Circuit layout still requires short feedback paths, clean grounding, and appropriate supply bypassing to preserve stability and low-noise performance. Typical uses include stereo audio preamplification, active tone control, headphone-buffer stages, mixer input conditioning, and general low-frequency signal processing. These applications align with the device's stated general-purpose amplifier classification and dual-channel configuration. Exact stability, bandwidth, noise, and output-drive claims should be checked against the official Texas Instruments datasheet before setting gain-bandwidth requirements. For new designs, verify the exact NE5532APG4 suffix, supply rails, input common-mode range, output swing, and thermal conditions in the manufacturer datasheet. When repairing an existing board, preserve the original pin orientation and socket the device only after confirming that the installed part is electrically and mechanically compatible. The 7.62 mm pitch through-hole package is mechanically different from common SOIC-8 variants even where some signal functions resemble them. This page consolidates verified distributor availability, package information, pricing, cross-reference research, and practical replacement guidance beyond a raw distributor listing. Unknown electrical values are deliberately identified rather than inferred from the broader NE5532 family.
NE5532D - Dual 10MHz Low-Noise Audio Op Amp | Texas Instruments (Tape & Reel)
The Texas Instruments NE5532D is a dual low-noise operational amplifier for audio applications, with two amplifier circuits, 5 nV/√Hz typical equivalent input noise at 1 kHz, and a 10 MHz typical unity-gain bandwidth in an 8-pin SOIC package. It is specified for total supply voltages from 10 V to 30 V, equivalent to ±5 V through ±15 V operation, making it suitable for conventional dual-polarity audio signal paths. An operational amplifier is an analog integrated circuit that uses high-gain differential feedback to amplify the difference between two input voltages. Within the broader hierarchy, the NE5532 is a dual operational amplifier, a low-noise voltage-feedback amplifier, and a linear amplifier used in audio preamplifiers, mixing consoles, active filters, and line-level driver circuits. Its two independent channels make it suitable for stereo audio or paired mono signal processing. Key characteristics include 5 nV/√Hz typical input noise at 1 kHz, 10 MHz typical unity-gain bandwidth, 100 dB typical DC voltage gain, 10 V/μs typical slew rate, and a typical 100 dB common-mode rejection ratio. The device also provides rail-to-rail output swing under the specified load conditions and low-distortion operation. The manufacturer identifies the NE5532 family for audio applications rather than precision instrumentation or micropower systems. The NE5532x family uses a conventional bipolar operational-amplifier architecture optimized for low noise and audio bandwidth. Its performance depends on supply voltage, output loading, gain, frequency, and bypass-capacitor implementation. Because the specified operating range includes ±5 V to ±15 V, downstream circuit headroom and output-swing limits must be checked against the actual load rather than inferred from the nominal supply rating. Typical applications include stereo preamplifiers, headphone-buffer stages, active crossover filters, audio mixers, line amplifiers, and small-signal buffer circuits. The dual configuration reduces package count when two related audio channels are required. A design should still verify stability, output-current capability, thermal conditions, and the selected feedback network rather than assuming every audio circuit has the same optimum gain or loading. The primary design consideration is power-supply decoupling and clean grounding. Place suitable bypass capacitors close to the supply pins, keep input and feedback routing short, and avoid high-impedance nodes adjacent to the amplifier inputs. The SOIC-8 package is a surface-mount SOIC family package intended for PCB assembly rather than through-hole insertion. This page combines the verified manufacturer and distributor information for NE5532D with package, application, design, and procurement context. Alternative substitutions are shown only where the retrieved web material supports a credible cross-reference; unavailable pricing and electrical details remain explicitly marked rather than inferred.

Its 10 MHz bandwidth provides more than enough bandwidth for many audio and general analog functions, while dual integration reduces component count compared with two separate single amplifiers. Designers should still verify gain, load, output swing, supply headroom, noise, and stability against the complete manufacturer datasheet before release. The D8 suffix identifies the verified 8-pin SOIC orderable offered by onsemi in the supplied distributor result. Place input and feedback components close to the relevant amplifier pins, maintain a continuous return path, and decouple the supply pins close to the package. Avoid leaving unused inputs floating; terminate them consistently with the chosen noise and bias-current strategy. This page consolidates verified distributor information, the manufacturer datasheet, strict package and pin constraints, and design guidance for NE5532D8. It distinguishes documented dual-amplifier functionality from unverified specifications by marking missing electrical details rather than estimating them.

A low-noise operational amplifier is a voltage-feedback amplifier designed to amplify weak signals while minimizing broadband noise. In the broader semiconductor hierarchy, the NE5532 belongs to operational amplifiers, analog amplifiers, integrated circuits, and signal-chain conditioning components. Its two integrated channels can process left and right audio signals, support instrumentation stages, or implement active filtering and buffering when the circuit operates within the manufacturer’s electrical limits. The principal verified features are dual-circuit integration, internal compensation, 1 uV input-noise class behavior, approximately 10 MHz bandwidth, and a 9 V/us slew rate. The low-noise characteristic is particularly useful in audio preamplifiers, where input-referred noise influences the audible signal floor. Its 10 MHz bandwidth also makes it more responsive than general-purpose precision amplifiers commonly used for slower instrumentation functions. Mouser describes the device as a dual low-noise commercial-temperature amplifier for a 3 V to 20 V supply range. The NE5532 architecture provides one amplifier per channel, with no external compensation network required.

These characteristics make it suitable for preamplifier gain stages, active filters, instrumentation, test equipment, and general low-frequency analog signal conditioning. Exact noise density, input-offset voltage, common-mode range, output-current capability, and temperature limits require confirmation from the manufacturer datasheet. When laying out an NE5532D8G board, preserve the SOIC-8 land pattern and observe the manufacturer’s input, output, supply, and bypass recommendations. Place supply-decoupling capacitors close to the supply pins and use short, low-loop feedback paths to reduce oscillation risk. Because audio and instrumentation circuits are sensitive to grounding and supply noise, a quiet reference return, symmetrical routing, and appropriate output-load compatibility are as important as nominal gain calculations. This product page combines verified distributor identification, source-linked availability information, exact known electrical values, and explicit data markers for unsupported specifications. It is intended to help engineers distinguish verified NE5532D8G attributes from unverified claims before making an audio, instrumentation, or analog-signal-chain design decision.
NE5532D8R2 - Dual Low-Noise Op Amp | onsemi | Audio
The onsemi NE5532D8R2 is a dual, internally compensated low-noise operational amplifier with two independent amplifiers in an 8-pin SOIC package.

A dual operational amplifier contains two amplifier channels in one package, allowing a circuit to process two related signals or to build stereo, differential, or multi-stage analog functions. The internally compensated architecture simplifies stable operation in typical closed-loop analog applications, while the low-noise characteristics make the device relevant to audio and measurement circuits. The NE5532 family is commonly associated with audio preamplification, microphone stages, active filters, and general instrumentation. The verified search results specifically describe the NE5532D8R2 as an internally compensated dual low-noise operational amplifier and identify its package as 8-SOIC. They do not provide a complete manufacturer electrical table, so detailed values such as input noise density, slew rate, bandwidth, common-mode range, output swing, input bias current, and temperature limits are marked as data needed rather than inferred. Typical circuit implementation places each amplifier channel in a feedback network, with external resistors setting closed-loop gain and filtering behavior. Decoupling capacitors should be placed close to the supply pins, and the unused channel should be configured according to the manufacturer’s recommended practice rather than left floating. The SOIC footprint supports conventional surface-mount assembly, although actual board layout, thermal behavior, and signal integrity still require validation. NE5532D8R2 pricing and detailed electrical performance must be confirmed against current authorized distributor inventory and the manufacturer datasheet. The verified distributor page reports current purchasing access, but the supplied data does not include numeric prices, stock quantities, or lead times. This page therefore distinguishes verified catalog facts from specifications requiring datasheet confirmation.

Its two independent channels make it suitable for stereo audio or paired mono signal processing. Key characteristics include 5 nV/√Hz typical input noise at 1 kHz, 10 MHz typical unity-gain bandwidth, 100 dB typical DC voltage gain, 10 V/μs typical slew rate, and a typical 100 dB common-mode rejection ratio. The device also provides rail-to-rail output swing under the specified load conditions and low-distortion operation. The manufacturer identifies the NE5532 family for audio applications rather than precision instrumentation or micropower systems. The NE5532x family uses a conventional bipolar operational-amplifier architecture optimized for low noise and audio bandwidth. Its performance depends on supply voltage, output loading, gain, frequency, and bypass-capacitor implementation. Because the specified operating range includes ±5 V to ±15 V, downstream circuit headroom and output-swing limits must be checked against the actual load rather than inferred from the nominal supply rating.

NE5532DR2G - Dual 10 MHz Low-Noise Op Amp | onsemi
The onsemi NE5532DR2G is an internally compensated dual low-noise operational amplifier supplied in a 16-SOIC package. The verified product data identifies a 10 MHz gain-bandwidth product, low-noise performance, improved output drive capability, and substantially higher small-signal and power bandwidth than older standard amplifiers such as the 1458. Each package contains two amplifiers, allowing stereo audio, balanced signal, or dual-channel instrumentation designs to use one IC rather than two single-channel devices. An operational amplifier is a voltage-controlled voltage-source amplifier that uses negative feedback to make its closed-loop behavior stable and predictable. The NE5532 belongs to the low-noise operational-amplifier hierarchy within analog and linear ICs. Its dual-channel architecture is useful wherever two related signals must be amplified with matched circuitry, while internal compensation avoids an external compensation network in ordinary closed-loop applications. The verified material specifically describes better noise performance, improved output drive, and higher small-signal and power bandwidth than conventional operational amplifiers such as the 1458. These characteristics make the device relevant to audio preamplification, filtering, signal conditioning, buffering, current sensing, analog measurement, and precision control. Exact input-offset voltage, input-bias current, slew rate, supply-current, output-current, and noise-density values are not present in the supplied source records and therefore remain data-needed rather than inferred. The NE5532DR2G uses a 20 V maximum supply classification in the verified GlobalSpec record and is identified as a dual operational amplifier in a SOIC package. Its internally compensated architecture is suited to conventional negative-feedback loops, but the actual usable bandwidth still depends on closed-loop gain, load, output amplitude, supply voltage, and PCB layout. Designers should avoid driving capacitive loads directly unless stability has been verified at the intended frequency. Typical uses include stereo audio input stages, active filters, low-level sensor amplification, analog control loops, and precision signal-conditioning blocks. The dual format can reduce package count in stereo or differential circuits, but both channels share the same supply pins and common ground. Decoupling and grounding remain as important as nominal noise specifications because supply coupling and ground impedance can degrade otherwise quiet measurements. For PCB implementation, place the bypass capacitor close to the supply pins and preserve a short, low-impedance return path. Decoupling capacitance and voltage rating must be selected from the complete circuit requirements because the supplied records do not state a manufacturer-recommended value. Stable feedback components and suitable source and sink loads are equally important when using the amplifier outside the manufacturer datasheet's exact test conditions. This page consolidates the verified distributor and source-page information, separates confirmed data from missing specifications, and adds engineering-focused application and design guidance. Distributor pricing and stock can change independently of the device, so the listed LCSC price is identified as a point-in-time commercial reference rather than a guaranteed quotation.

The dual configuration reduces package count when two gain stages are required. For stable operation with a minimal external network, place the manufacturer-recommended bypass capacitors close to the supply pins and route traces away from noisy power and digital signals. Input and output impedance, load capability, output swing, distortion, and common-mode headroom determine the usable bandwidth. Do not assume the 10 MHz small-signal bandwidth remains available at every gain, voltage, and load condition. NE5532DRG4 is supplied in tape-and-reel packaging for automated assembly. This page combines verified distributor information, the Texas Instruments product description, same-package substitution guidance, and practical design notes to support sourcing and engineering selection without implying that merely similar amplifiers are automatically drop-in replacements. A pin-to-pin alternative must match the dual 8-SOIC footprint and pin functions as well as the voltage, bandwidth, noise, slew-rate, and drive requirements. Circuit-level substitution should also verify supply rails, gain configuration, output loading, distortion, stability, and intended audio performance. The comparisons below distinguish verified facts from parameters that still require manufacturer-specific confirmation.

For design implementation, use the manufacturer's specified supply voltage, common-mode limits, output-current capability, input-bias-current behavior, noise figures, and compensation guidance. Decoupling capacitors should be placed close to the supply pins, and analog-signal routing should avoid noisy switching nodes and high-impedance traces. Verify stability at the intended gain, load capacitance, output amplitude, and temperature rather than relying only on nominal bandwidth. This page combines the verified package, bandwidth, slew-rate, distributor, and cross-reference information with practical selection guidance.
