The datasheet snippet reports 103µV noise in single-ended configuration. Integrated features include startup and shutdown pop elimination, short-circuit protection, and 4.5A short-circuit current limiting, with automatic restart after the fault clears. The amplifier supports either two stereo single-ended outputs or one mono bridge-tied-load output. This flexibility permits the same device family to address stereo speakers, compact subwoofers, multimedia speakers, consumer audio equipment, and powered portable equipment. At 24V VDD, its available output-power capability is substantially higher than devices rated only for low-voltage portable applications. Output topology is the principal design consideration. Single-ended mode drives each speaker terminal relative to ground, whereas bridge-tied-load mode uses both output channels so the speaker sees the differential voltage. The latter increases available voltage swing and supports the 50W mono result, but it must not be used with a speaker connected from either output to ground. Verify pin functions, exposed-pad layout, decoupling, thermal performance, and output topology against the manufacturer datasheet before layout release. This product page consolidates verified manufacturer specifications, distributor listing data, package information, and practical selection guidance. Pricing, detailed electrical limits, full pin naming, compliance declarations, and lifecycle status remain dependent on current authorized-source data because those values were not established by the supplied search extract.

The exposed pad supports heat transfer from the power stage, but thermal performance still depends on PCB copper, layer count, airflow, load duration, and adjacent heat sources. Typical uses include consumer speakers, multimedia audio, compact stereo systems, sound bars, portable powered speakers, and mono subwoofer or full-range speaker designs. The MP7748SGF is appropriate when local analog amplification is preferred and a Class D efficiency advantage is useful, but it may not suit systems that require a digital input because the verified material identifies an analog-input family. For layout, follow the manufacturer datasheet connection and thermal recommendations exactly. Keep the exposed-pad thermal path unobstructed, provide adequate input and output filtering, and account for switching-node layout and ground-return control. Do not assume a generic 28-pin footprint or replace the amplifier without checking exposed-pad geometry, pin names, thermal requirements, and load compatibility. This page consolidates manufacturer specifications, distributor listings, cross-reference evidence, and practical Class D design guidance. Exact pricing, lifecycle status, complete electrical limits, and several physical details were not supplied by the verified sources and are therefore identified rather than guessed.
MP7748SGF-Z - 60W Class D Audio Amplifier | MPS
The Monolithic Power Systems MP7748SGF-Z is a fully integrated Class D audio amplifier capable of delivering 2 x 30 W stereo single-ended output or 60 W mono bridge-tied-load output in a 28-pin TSSOP-EP package. The verified family data identifies integrated 200 mΩ power MOSFETs, startup and shutdown pop-elimination circuitry, and short-circuit protection. A Class D audio amplifier is a switching power amplifier that uses pulse-width modulation to drive speakers with high efficiency while filtering the switching waveform into an audio output. It belongs to the audio amplifier hierarchy, where its efficiency and output power can exceed those of conventional linear Class A/B amplification. The MP7748S uses proprietary variable-frequency topology and is designed for compact consumer-audio and multimedia systems. The amplifier supports two 30 W channels into 4 Ω speakers when configured as single-ended stereo, or one 60 W channel into an 8 Ω speaker when its outputs are combined in bridge-tied-load mode. This flexibility allows one device family to address stereo speakers, a mono subwoofer, a compact monitor, or a consumer-audio terminal. Integrated power MOSFETs reduce external component count and simplify the output stage. The supplied manufacturer search result states that the MP7748S provides high fidelity comparable to Class A/B amplification at high Class D efficiency. Variable-frequency operation can also reduce low-frequency interference concerns associated with a fixed switching frequency, although frequency-dependent EMI evaluation remains essential. Input filtering, output reconstruction, speaker load, thermal conditions, and supply decoupling determine final acoustic and system performance. Typical uses include compact stereo systems, portable or multimedia speakers, home-theater amplification, powered subwoofers, smart displays, and compact consumer-audio products. In single-ended operation, each channel drives a speaker independently; in bridge-tied-load operation, the two outputs work together so the speaker sees the differential voltage without tying either output to ground. Layout is critical because the exposed pad and output traces carry power while the audio input is sensitive to switching and ground noise. Place input filtering and decoupling near their associated pins, keep loudspeaker outputs away from the analog input, and use the manufacturer’s datasheet land pattern and output-filter recommendations. Verify thermal performance, speaker impedance, and protection behavior in the final enclosure. This page combines verified manufacturer and distributor data with application guidance, source traceability, and drop-in-replacement analysis. It explicitly distinguishes confirmed MP7748SGF information from target-ordering and package details that were not supplied, avoiding unsupported electrical or commercial assumptions.
MP7751GF-Z - 2x20W Stereo Class-D Audio Amplifier | MPS
The Monolithic Power Systems MP7751GF-Z is a fixed-frequency, stereo, analog-input Class-D audio amplifier delivering 2 x 20 W into 8-ohm speakers at an 18 V supply. It operates from 5 V to 26 V and is packaged in a 28-pin TSSOP with exposed pad. The integrated solution is designed to reduce board size by combining 240 mΩ power MOSFETs, start-up and shutdown pop elimination, short-circuit protection, and advanced EMI performance. A Class-D audio amplifier is a switching power amplifier within the broader audio-amplifier and power-management semiconductor hierarchy. Instead of continuously dissipating a signal through linear output devices, it uses efficient switching stages to drive a speaker load. The MP7751 uses a bridge-tied-load topology, which means each speaker is connected between two switching outputs rather than to ground. This improves output-voltage utilization and can provide substantial audio output from a compact integrated circuit. Key verified features include a 5 V to 26 V supply range, stereo operation, 20 W per channel at 18 V into 8 ohms, and a fixed switching-frequency implementation. The integrated 240 mΩ power MOSFETs reduce external component count, while short-circuit protection improves robustness in speaker-drive applications. The exposed thermal pad supports heat transfer through the PCB, although thermal design must account for the amplifier dissipation and copper area. The MP7751GF-Z is positioned for analog audio systems requiring compact stereo amplification, including powered speakers, consumer audio equipment, small multimedia systems, and portable or compact audio products. Compared with a discrete MOSFET output stage, the integrated amplifier simplifies layout and reduces component count. Compared with a higher-power external amplifier, the MP7751 is appropriate when the required speaker load is near 20 W per channel and the available supply is within its verified operating range. The main design consideration is power-thermal management. Class-D efficiency does not eliminate heat: output-stage loss still depends on supply voltage, load impedance, output power, switching characteristics, and copper thermal resistance. Layout should follow the manufacturer datasheet exactly, preserve the exposed-pad connection, keep switching loops compact, and provide adequate input filtering. Speaker wiring should remain short and separated from sensitive analog input routing to reduce EMI pickup and pop artifacts. This page combines verified manufacturer and distributor information with practical guidance on analog-input filtering, exposed-pad thermal design, speaker protection, and application selection. Pricing and availability must be checked as of 2026-10-22 because distributor inventory and terms can change without notice.
MP7752GF - 2x15W Stereo Class D Audio Amplifier
The Monolithic Power Systems Inc. MP7752GF is a stereo Class D audio amplifier IC with 2 x 15 W output power, an 18 V supply rating, analog input, fixed-frequency operation, and bridge-tied-load speaker drive. It is supplied in a 28-pin TSSOP with exposed pad. The device is designed for compact, integrated Class D audio systems where output-stage inductors and LC filters are not required. An inductorless Class D amplifier is a switching audio amplifier that uses integrated power MOSFETs to deliver high output power efficiently while driving speakers directly in a bridge-tied-load arrangement. The MP7752GF belongs to the amplifier-IC, audio-amplifier, Class D, and power-management semiconductor hierarchy. Its integrated power stage, short-circuit protection, start-up/shutdown pop elimination, and advanced EMI performance support compact consumer audio products. The verified source data identifies the MP7752GF as a 2-channel stereo Class D amplifier rated at 18 V and 2 x 15 W. It integrates 240 milliohm power MOSFETs and uses bridge-tied-load output topology. The fixed-frequency switching architecture removes the need for an external output inductor, reducing board area compared with conventional filter-based Class D solutions. The exposed-pad package also provides a thermal connection from the power stage to the PCB. Typical applications include compact stereo speakers, portable consumer audio products, multimedia systems, USB or docking audio products, and other low-voltage audio equipment requiring efficient amplification. In a typical bridge-tied-load implementation, the two amplifier outputs drive the two speaker terminals, so the speaker load sees differential voltage rather than being connected to ground. The principal design consideration is thermal management. Although the integrated MOSFETs eliminate external output inductors, Class D switching and bridge-tied-load operation still generate heat that must leave through the exposed pad and surrounding copper. PCB thermal vias, adequate copper area, and careful placement of input, power, and output connections are important for reliable operation. This product page combines the verified distributor description, manufacturer datasheet identification, package information, and cross-reference results. Pricing, exact operating conditions, protection thresholds, efficiency curves, and complete pin-level electrical characteristics must be confirmed against the manufacturer datasheet before design release.
MP7752GF-Z - 2x15W Stereo Class-D Amplifier | MPS
The Monolithic Power Systems MP7752GF-Z is a two-channel, analog-input, inductorless Class-D stereo audio amplifier rated for 2 x 15 W output into 8-ohm speakers. It operates from a 5 V to 18 V supply and uses bridge-tied-load (BTL) outputs, in a 28-pin TSSOP-EP package. A Class-D audio amplifier converts a comparatively low-power analog input into a high-efficiency PWM power stage that delivers energy directly to the speaker load. The MP7752 integrates 240 mOhm power MOSFETs, eliminating the need for external output inductors and reducing board area. Its fixed-frequency architecture supports filterless operation when the system does not require a reconstructed low-pass signal at the speaker output. Verified features include a 2 x 15 W BTL output configuration, two pairs of differential inputs, short-circuit protection, startup and shutdown pop suppression, automatic mute or no-noise switching, automatic power saving, and 90% efficiency. The listed THD is 0.5%, with a -60 dB figure and 100 dB also appearing in the verified distributor listing, although the exact test conditions for those entries require confirmation in the manufacturer datasheet. The MP7752GF-Z is suitable for compact stereo audio products, multimedia speakers, USB or Bluetooth audio accessories, soundbars, and powered speaker systems. Its differential input architecture helps reject common-mode noise when the source is balanced or when a suitably designed input network is used. The exposed-pad package supports thermal performance, but actual output power and distortion depend strongly on supply voltage, speaker impedance, PCB copper, thermal design, and load tolerance. The key design consideration is the exposed thermal pad. Place the pad over a continuous ground or thermal-copper area with multiple short vias and follow the manufacturer land pattern. Decouple the supply locally, keep speaker outputs away from sensitive input routing, and validate EMI performance because Class-D PWM outputs contain high-frequency energy. Confirm all absolute maximum ratings, pin functions, thermal resistance values, and application limits against the official datasheet before release. This page combines verified distributor specifications, the official MPS product-document result, package and sourcing information, and engineering-focused usage guidance. Pricing and availability remain distributor-dependent, so the tiers shown here should be treated as reference data only, as of 2026-10-22, unless separately confirmed.
MP7770GF-Z - 90W Class-D Audio Amplifier | MPS
The Monolithic Power Systems MP7770GF-Z is an analog Class-D audio amplifier IC capable of delivering 2 x 45 W stereo single-ended output or 90 W mono bridge-tied-load output from a 36 V VDD supply. It is packaged in a 28-TSSOP-EP package. What is a Class-D audio amplifier? A Class-D amplifier is an audio power amplifier whose switching output stage delivers energy to a speaker more efficiently than a traditional linear Class-A/B design. The MP7770 uses MPS proprietary variable-frequency topology to combine high output power with compact integration. It supports either two single-ended speaker channels or one bridge-tied-load speaker, making it adaptable to stereo and compact high-power audio systems. The MP7770 integrates 100 mOhm power MOSFETs, startup and shutdown pop-elimination circuitry, and short-circuit protection. According to the manufacturer product page, its fully integrated amplifier architecture reduces solution size. The MP7770GF is also available on the EV7770-F-00A evaluation board for single-ended configurations, providing a practical platform for evaluating 45 W per channel into 4 Ohm speakers at up to 36 V VDD. The manufacturer datasheet identifies the MP7770GF family as an analog Class-D audio amplifier with variable-frequency operation. The output topology determines the power configuration: two channels can each deliver 45 W into 4 Ohm speakers in single-ended mode, while a bridged configuration can deliver 90 W into 8 Ohm. The bridge-tied-load topology is useful when the system requires one higher-power speaker output rather than two independent channels. Typical applications include compact stereo audio systems, multimedia speakers, powered subwoofers, consumer audio equipment, and industrial or communications speaker systems. When designing the board, provide a clean supply path, adequate thermal copper around the exposed pad, and speaker protection appropriate to the selected output topology. The most important design tradeoff is power delivery versus thermal and supply capability. At 36 V VDD, the stated output ratings are 45 W per channel or 90 W in bridged mode, but actual continuous output depends on speaker impedance, supply voltage, thermal conditions, and the amplifier's operating limits. This page consolidates the verified product data, comparison fields, alternatives, and design guidance relevant to MP7770GF-Z. According to the verified data, MP7770GF-Z is offered as a 28-TSSOP-EP Class-D audio amplifier by Monolithic Power Systems and is associated with the MP7770GF family.
MP8103DK-LF - Dual 200kHz Rail-to-Rail Op Amp | MPS
The Monolithic Power Systems MP8103DK-LF is a dual, rail-to-rail-output operational amplifier rated for a 5 V supply, with a 200 kHz gain-bandwidth product, 82 dB CMRR, 0.1000 V/µs slew rate, and an 8-MSOP package. The two amplifiers are intended for low-voltage signal conditioning where compactness, low power, and rail-to-rail output operation are useful. Verified distributor descriptions identify this device as a standard general-purpose, dual amplifier, while the supplied datasheet snippets confirm its 5 V supply condition, 82 dB CMRR, 0.1000 V/µs slew rate, −40 °C to +85 °C operating range, MSOP-8 package, and RoHS-compliant status. An operational amplifier is an analog integrated circuit that compares two input voltages and drives its output toward a higher level when the noninverting input exceeds the inverting input. Within the amplifier hierarchy, the MP8103 is an operational amplifier IC, also called an op amp, within analog and amplifier semiconductors. A dual device contains two amplifier channels, allowing one package to serve two related signal paths. Rail-to-rail output means the output can approach the supply rails under suitable load and output conditions, making the device relevant to low-voltage systems whose usable signal range extends close to the rails. The verified data highlights a 200 kHz gain-bandwidth product, 82 dB common-mode rejection ratio, and 0.1000 V/µs slew rate. These figures describe the amplifier’s speed and immunity to signals common to both inputs. The 200 kHz bandwidth is relevant for signal paths that do not require high-frequency operation, while the 82 dB CMRR indicates rejection of common-mode interference. The 8-MSOP format supports compact PCB layouts, and the dual-channel configuration can reduce the number of packages compared with using separate single amplifiers. The MP8103 family is described as a single-supply, rail-to-rail-output operational amplifier. The verified search data also reports operation from a supply as low as 1.8 V for the MP8103 family and approximately 14 µA supply current in one related family description. For the exact MP8103DK-LF, use the manufacturer datasheet for full electrical limits, input range, output behavior, stability, and recommended operating conditions. The −40 °C to +85 °C operating-temperature specification is available for this exact part in the supplied search data. Typical applications include low-voltage sensor interfaces, buffered analog measurements, audio or communications signal conditioning, and general embedded analog systems where two amplifier channels are useful. Because the available verified data does not provide a genuine manufacturer PDF URL, application-specific limits, or complete pricing values, those fields are marked as needed rather than estimated. Engineers should confirm the exact pinout, supply limits, input common-mode range, output swing, noise, and stability requirements against the official MP8103 datasheet before production release.
MP8110DK-LF - 40V High-Side Current-Sense Amplifier | MPS
Monolithic Power Systems MP8110DK-LF is a low-cost, precision, high-side current-sense amplifier designed for current monitoring from a single 2.5V to 40V supply. The device provides a single amplifier channel in an 8-MSOP package and is intended for notebook computers, cell phones, battery-powered systems, and other applications where DC load-current measurement is required. Its high-side placement avoids interrupting the monitored power path and allows the sensed current to be measured relative to ground. A current-sense amplifier is an analog signal-conditioning device that measures the voltage drop across a small sense resistor and produces an output proportional to the current flowing through that resistor. The MP8110 family belongs to the precision analog and current-measurement hierarchy, supporting high-side current sensing, power-system monitoring, battery management, load detection, and overcurrent protection. Its low supply current helps preserve battery life in portable systems. The manufacturer describes the MP8110 as operating from 2.5V to 40V and typically consuming 12 µA. The device output is proportional to load current, and the MP8110 evaluation-board information states that 1V output corresponds to 5A of load current. This relationship depends on the selected sense resistor and device gain; the exact gain, common-mode range, accuracy, and electrical limits should be confirmed in the manufacturer datasheet before final design release. High-side current sensing places the sense resistor in the positive supply conductor, so the amplifier can monitor current without disconnecting the load or placing a high-side transistor in the power path. This is useful in battery-powered equipment where the ground connection must remain common with the monitored system. The approach can also simplify power-path protection because the load remains connected during measurement. The MP8110 is suitable for notebook computers, cell phones, battery-operated instruments, industrial control systems, power adapters, and other DC rails where current monitoring is valuable. In these applications, the amplifier output can be connected to an analog-to-digital converter, comparator, microcontroller input, or system controller for current reporting, load detection, and protection. The 40V supply capability is useful for systems whose monitored rail is above conventional low-voltage logic levels. Designers should verify the sense-resistor value, Kelvin routing, amplifier gain, output swing, supply decoupling, and input common-mode limits against the specific MP8110 ordering code and datasheet. Keep the sense-resistor connections short and symmetrical to reduce parasitic resistance and measurement error. Place the amplifier and filtering components close to the sense resistor, and provide stable supply bypassing where required by the application. This page summarizes the verified manufacturer and distributor information for MP8110DK-LF and distinguishes confirmed specifications from parameters that require datasheet confirmation. It also provides application guidance and procurement context for engineers comparing high-side current-sense amplifier options.
MPY100AG - 4-Quadrant Analog Multiplier/Divider | Texas Instruments
The Texas Instruments MPY100AG is a precision 4-quadrant analog multiplier/divider originally developed by Burr-Brown, delivered in a 14-pin ceramic CDIP (0.300 inch, 7.62 mm) package and operating from dual supplies of 8.5 V to 20 V (typically +/-15 V DC). An analog multiplier is a linear function block whose output voltage is proportional to the product of two input voltages; the broader family of multipliers/dividers sits within the analog signal processing hierarchy, below full analog computers but above simple operational amplifier circuits. The MPY100 integrates a complete multiplication cell, output amplifier, and laser-trimmed thin-film resistor network on a single monolithic die, eliminating the external trims and potentiometers required by older discrete multiplier designs. Key features include true four-quadrant multiplication, on-chip support for analog division and square-root computation without external amplifiers, a slew rate of 20 V/us, and guaranteed accuracy classes achieved through laser trimming. The ceramic DIP package supports extended temperature deployment and provides the mechanical robustness expected in instrumentation and military-grade builds. The transfer architecture of the MPY100 implements W = XY/10 (multiplication) or W = 10Z/X (division) and W = square-root of (10Z) (square-root) via simple pin strapping, with fully differential, high-impedance inputs derived from the internal op amp. Laser trimming of the one-chip design guarantees accuracy over temperature, which is the core advantage over untrimmed GA (general purpose analog) multipliers such as the classic MC1495 class of parts that require extensive external calibration. Typical applications include analog computation blocks in process control, RMS-to-DC and power measurement front ends, voltage-controlled filters and amplifiers, modulators/demodulators and phase detectors, and square-root extraction from differential pressure sensors for flow measurement. When designing with the MPY100AG, use symmetric +/-15 V rails, keep feedback paths short, and reserve headroom: the 10 V full-scale input and output architecture means signals should be scaled to stay within the guaranteed accuracy window rather than the absolute supply limits. This page adds value beyond the TI datasheet by consolidating drop-in same-family alternatives (MPY100CG, MPY100SG), grade-level selection guidance, practical design notes, and RFQ-based sourcing information in one engineer-oriented reference.
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. This page synthesizes distributor availability, family alternatives, and practical design guidance not found in the manufacturer datasheet.
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. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
