LM2904N - Dual 1 MHz 26 V Op Amp | Texas Instruments

Texas Instruments LM2904N is a dual, internally frequency-compensated operational amplifier with two independent amplifiers, a 26 V maximum supply designation, and a 1 MHz gain-bandwidth product. It is supplied in an 8-pin PDIP package. The device is designed for general-purpose signal conditioning from industrial control to audio and sensor interfaces. An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. Internally compensated LM2904N amplifiers are voltage-amplifier building blocks within the operational-amplifier, analog IC, and semiconductor hierarchies. Their differential inputs support filtering, buffering, summing, comparison, and feedback-control functions without requiring an external compensation network. The verified product information identifies two amplifiers, single-supply or split-supply use, low power drain, and a common-mode input range extending to ground or VEE. Its internally frequency-compensated architecture simplifies closed-loop design, while the dual configuration places two matched-function amplifiers in one package. However, the supplied data does not state output-current capability, input-offset voltage, input-bias current, slew rate, noise density, or operating-temperature limits. A key design consideration is supply configuration. Although the official TI product-page snippet specifies a 26 V product family designation, engineers must consult the exact manufacturer datasheet before setting rail voltage, input common-mode limits, output swing, and load current. Decoupling capacitance, input impedance, feedback topology, output loading, and thermal dissipation also remain datasheet- and layout-dependent. Typical uses include two-channel sensor conditioning, low-frequency active filters, audio preamplification, comparator-style signal detection with suitable saturation limits, control-loop buffering, and general dual-rail analog signal processing. The 1 MHz bandwidth is most appropriate for low-to-moderate-frequency signals rather than high-speed precision instrumentation. This data page combines verified manufacturer and distributor facts, pin-compatible replacement screening, and practical engineering guidance. It deliberately leaves unverified electrical values marked for completion rather than inferring specifications from related dual-amplifier families.

LM2904P

LM2904P - Dual 26V 700kHz Op Amp | Texas Instruments

The Texas Instruments LM2904P is a dual, general-purpose operational amplifier designed for single- or dual-supply operation up to 26 V, with a 700 kHz gain-bandwidth product and two amplifiers per package. The LM2904P is supplied in an 8-pin PDIP package, making it suitable for through-hole industrial, instrumentation, and control designs. According to the Texas Instruments product page, the device is a standard dual operational amplifier rather than a low-noise or precision amplifier. An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. In a closed-loop configuration, external feedback components define the gain, bandwidth, filtering, and signal behavior. The LM2904P belongs to the broader hierarchy of operational amplifier, analog amplifier, and semiconductor, while its dual configuration saves board area by placing two amplifiers in one package. The verified manufacturer information identifies a maximum 26 V supply-related range and 700 kHz performance. The package is 8-PDIP. Texas Instruments describes the LM2904 as an industry-standard dual operational amplifier family, but the supplied verified data does not include a complete electrical parameter table. Consequently, input offset voltage, input bias current, output current, noise, common-mode range, slew rate, operating temperature, and exact electrical limits are marked as data needed rather than inferred. LM2904P circuits are commonly considered for sensor amplification, buffered analog signals, low-frequency active filters, and general-purpose control loops. Because it is a standard dual amplifier in a through-hole package, it is especially useful for prototypes, educational boards, legacy equipment, and industrial control systems where DIP packaging simplifies manual assembly and inspection. The second amplifier can mirror the first stage, provide filtering, buffer an output, or implement another independent channel. Designers should verify supply polarity, input common-mode limits, output swing, stability with the selected load, and capacitor values against the full manufacturer datasheet before production use. Decoupling capacitors should be placed close to the supply pins, and feedback components should be kept compact to reduce parasitic capacitance. If low-noise, rail-to-rail input/output, high-frequency, or automotive-qualified performance is required, a different amplifier family should be selected after reviewing the complete electrical data. This page consolidates the verified Texas Instruments product description, distributor identification, and package information with engineering guidance, comparison points, and procurement-oriented details for LM2904P users.

LM2904P3 - Dual 26V 700kHz Op Amp | Texas Instruments

Texas Instruments LM2904P3 is a dual general-purpose operational amplifier with two amplifier circuits, a 26 V maximum supply rating, 700 kHz gain-bandwidth performance, and an 8-pin PDIP package. It is designed for conventional analog signal-conditioning applications where a wide supply-voltage range and two amplifiers per package are useful. An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify the difference between signals applied to its inverting and non-inverting inputs. The LM2904 belongs to the operational-amplifier hierarchy, which includes voltage-feedback amplifiers, general-purpose amplifiers, instrumentation amplifiers, and precision amplifiers. Two amplifiers in one package can reduce board area when a circuit needs matched functions such as buffering, amplification, filtering, or differential sensing. The verified manufacturer information identifies the LM2904 as a dual, 26 V, 700 kHz operational amplifier. The LM2904P3 orderable is identified as a general-purpose, two-circuit amplifier in an 8-PDIP package. Its dual configuration allows both amplifier sections to share one package while retaining independent inputs and outputs. The 26 V rating permits operation from higher-voltage analog systems than typical low-voltage mixed-signal amplifier families. The 700 kHz gain-bandwidth figure defines the practical frequency range for many small-signal applications. It is relevant when closing an amplifier around a feedback network, because the amplifier must provide adequate loop gain and phase margin at the intended signal frequency. General-purpose performance makes the device suitable for signal amplification, voltage buffering, active filtering, and feedback-control stages where specialized precision or high-speed parameters are not required. Typical uses include industrial sensor interfaces, low-frequency active filters, audio preamplifier stages, analog control loops, and general instrumentation. In a dual-amplifier circuit, one section can perform signal conditioning while the other supplies inversion, feedback, or buffering. The package is also appropriate for through-hole industrial designs where DIP mounting remains preferable to fine-pitch surface-mount assembly. Designers should verify the complete electrical limits, electrical characteristics, pin configuration, common-mode range, output swing, input bias current, slew rate, and stability requirements in the manufacturer datasheet before finalizing a design. Decoupling, input and output signal limits, common-mode voltage, and thermal conditions must be evaluated for the exact operating environment. This page consolidates the verified 26 V and 700 kHz device facts, distributor pricing information, package data, and same-family replacement guidance. It also adds practical selection criteria and design notes that help engineers distinguish a true 8-pin drop-in option from alternatives requiring a different footprint.

The Texas Instruments LM2904PW is a dual general-purpose operational amplifier with a 700 kHz gain-bandwidth product, 26 V maximum supply capability, and an 8-pin TSSOP package. The device contains two independent, frequency-compensated amplifiers that can operate from a single supply or split supply, making it suitable for signal conditioning, buffering, and general-purpose analog control applications. Its 0.7 mA typical supply-current drain is specified as being independent of supply voltage, helping conserve power across a broad operating range. An operational amplifier, or op amp, is an analog integrated circuit that uses high open-loop gain to amplify the difference between two input voltages. A dual op amp combines two amplifiers in one package, allowing both channels to share a supply while remaining electrically independent. Within the broader semiconductor hierarchy, the LM2904PW belongs to the amplifier IC, operational-amplifier, analog-signal-conditioning, and integrated-circuit families. It is a widely recognized general-purpose alternative to newer precision and low-noise amplifier families when voltage range, low power, and functional simplicity matter more than low offset or rail-to-rail operation. The principal operating characteristics include a 26 V maximum supply voltage, a 700 kHz gain-bandwidth product, two amplifier circuits, and a typical supply-current drain of 0.7 mA. The common-mode input range includes ground, allowing the device to sense input signals close to the negative supply rail. Low input-bias and input-offset parameters are identified in the device literature, although exact minimum and maximum limits are not included in the retrieved data. The LM2904PW therefore provides a practical balance of gain bandwidth, supply flexibility, and low supply-current demand. Internally, the LM2904 uses a frequency-compensated voltage-feedback architecture. This internal compensation means each amplifier can provide stable closed-loop operation without an external frequency-compensation network when configured for typical noninverting or inverting gains. The design is intended for general-purpose analog systems rather than precision instrumentation. Its 700 kHz gain-bandwidth product is adequate for audio-frequency signal conditioning, low-rate data acquisition, sensor interfaces, and industrial control blocks, but it is substantially slower than precision, high-speed, or rail-to-rail amplifier families. Typical uses include general-purpose signal amplification, low-frequency active filtering, current-to-voltage conversion for sensors, audio preamplification, comparator-style threshold conditioning with suitable output limits, and industrial control interfaces. The ability to operate from single or split supplies makes the part useful in systems whose signal range is referenced to ground. For battery-powered equipment, the typical 0.7 mA supply-current drain helps limit consumption, although the complete system current also depends on output current, load, amplifier configuration, and supply voltage. Designers should verify the exact common-mode, output-swing, offset-voltage, input-bias-current, slew-rate, and temperature limits from the manufacturer datasheet before fixing operating conditions. Input and output stability depends on layout, source impedance, load, and feedback topology. Decoupling should be placed close to the supply pins, and sensitive layouts should minimize parasitic capacitance and leakage around high-impedance inputs. The 8-pin TSSOP footprint is compact but requires careful lead pitch and thermal considerations during assembly. This product record combines the verified manufacturer identity, package, voltage, bandwidth, and power information with distributor pricing and cross-reference evidence. It also adds practical application guidance, honest substitution limits, package-level comparison data, and design notes intended to help engineers evaluate the LM2904PW beyond a raw distributor listing.

LM2904PWRG3 - Dual 26V 700kHz Op Amp | Texas Instruments

The Texas Instruments LM2904PWRG3 is a dual general-purpose operational amplifier rated for a 26 V maximum total supply voltage and a 700 kHz gain-bandwidth product, supplied in an 8-pin TSSOP package. The device contains two independent, internally frequency-compensated amplifiers, allowing one package to provide two separate analog signal-processing channels. Its 0.3 V/us slew rate supports general-purpose applications requiring stable amplification from low-frequency instrumentation signals. An operational amplifier is a voltage-gain semiconductor that uses high open-loop gain and negative feedback to amplify small voltage differences. The dual-amplifier configuration belongs to the broader hierarchy of analog signal-chain ICs, analog ICs, and semiconductors. Operational amplifiers are commonly used in sensor conditioning, current sensing, error amplifiers, voltage followers, filters, and signal-conversion circuits where a predictable closed-loop response is more important than very high speed. The LM2904PWRG3 is designed for cost-sensitive, general-purpose systems rather than precision or high-speed signal-chain applications. According to the Texas Instruments LM2904 product information, the device is specified as a dual 26 V, 700 kHz operational amplifier. The manufacturer documentation also describes the LM2904 family as providing two independent, high-gain, frequency-compensated amplifiers that can operate from a single supply or split supplies. A low 0.7 mA typical supply-current drain is identified in the device documentation, helping reduce system power consumption when both channels remain active. The wide supply-voltage capability makes the amplifier applicable to industrial control, automotive-style signal conditioning, test equipment, and embedded analog interfaces. Each amplifier can be configured with external resistors or capacitors as an inverting amplifier, non-inverting amplifier, voltage follower, comparator-style stage, or active-filter element. Internal frequency compensation removes the need for an external compensation capacitor in ordinary closed-loop configurations, simplifying implementation while preserving stable operation for typical feedback networks. The TSSOP-8 package provides a compact surface-mount footprint suitable for high-density analog boards. Because the device supports single-supply or split-supply operation, the circuit designer must still define the input common-mode range and output swing relative to the selected rails. Input and output voltages must remain within the limits defined by the manufacturer datasheet, and unused amplifier inputs should be biased to prevent undefined operation. This product page combines the verified manufacturer characteristics, package information, sourcing links, application guidance, and drop-in comparison data into an engineering-focused reference. It also highlights where the LM2904PWRG3 is appropriate and where higher precision, wider bandwidth, lower noise, or automotive qualification is required.

LM2904PWRG4 - Dual 26V 700kHz Op Amp | Texas Instruments

The Texas Instruments LM2904PWRG4 is a dual general-purpose operational amplifier with a 26 V maximum supply rating, 700 kHz gain-bandwidth product, and an 8-pin TSSOP package. It contains two internally frequency-compensated amplifiers and operates from single or split supplies, making it suitable for cost-sensitive industrial and consumer signal-conditioning designs. An operational amplifier is a high-gain differential amplifier used to compare or amplify small voltage signals. The LM2904 belongs to the operational-amplifier hierarchy, where an op amp forms part of a broader analog and mixed-signal processing system. Its low supply-current consumption, common-mode input range that includes ground, and wide supply-voltage range make it useful in sensor interfaces, buffer stages, audio paths, and low-to-moderate-frequency control loops. The two channels provide approximately 0.3 V/us slew rate, 3 mV typical input offset voltage, 2 nA typical input offset current, and 20 nA typical input bias current. Typical supply-current consumption is 0.7 mA. Internal frequency compensation removes the need for external compensation in conventional closed-loop configurations, while the common-mode range extending toward ground supports direct sensing of signals near the lower supply rail. Each channel can operate independently, allowing simultaneous amplification, filtering, voltage comparison, or buffering. The device includes input-bias-current compensation and differential-input protection through internal clamp structures, supporting operation in conventional industrial control and instrumentation circuits. Designers must still observe the absolute maximum ratings for supply voltage, input voltage, current, junction temperature, and package power dissipation. Typical uses include low-frequency sensor conditioning, 4-20 mA receiver stages, audio preamplification, comparator-based control, active filters, and general-purpose analog interfaces. The dual configuration reduces component count when two independent analog functions are needed, while the compact TSSOP package suits densely assembled control boards. The main design consideration is bandwidth and stability. The 700 kHz gain-bandwidth product and 0.3 V/us slew rate are appropriate for low-frequency precision and general-purpose circuits, but they do not target high-speed signal chains. Check the required closed-loop gain, output swing, load impedance, supply voltage, and input common-mode range against the manufacturer datasheet. This product page combines the device specifications, application guidance, same-footprint alternatives, and engineering-oriented selection considerations. It also identifies where a redesign should focus on supply range, slew rate, precision, or package compatibility rather than treating every dual op amp as an interchangeable replacement.

LM2904Q2T - Dual 1.1 MHz Op Amp | STMicroelectronics

STMicroelectronics LM2904Q2T is a low-power dual bipolar operational amplifier containing two independent, internally frequency-compensated amplifiers. Each channel provides a 1.1 MHz gain-bandwidth product, 0.6 V/us slew rate, and approximately 100 dB open-loop gain. The device operates from 3 V to 30 V and is supplied in an 8-pin DFN package measuring 2 mm by 2 mm, making it suitable for compact, general-purpose analog signal-processing systems. An operational amplifier is an active analog semiconductor that compares two input voltages and drives its output toward the higher-voltage input. In negative-feedback configurations, it amplifies differential signals while maintaining high input impedance and low output impedance. The LM2904Q2T belongs to the operational-amplifier hierarchy: dual amplifier, voltage-feedback amplifier, analog IC, and semiconductor. Two independent channels allow one package to implement two separate signal paths. Key characteristics include a 1.1 MHz gain-bandwidth product, a 0.6 V/us slew rate, approximately 100 dB gain, and low-power bipolar operation. The manufacturer's listed input-current characteristics include 20 nA and 2 nA. Internal frequency compensation simplifies closed-loop amplifier selection, allowing common gains to be implemented without external compensation components. A wide 3 V to 30 V operating range also supports both conventional 5 V analog systems and higher-voltage industrial rails. The two amplifiers operate independently, which prevents signal or output interaction between channels except through their shared supply connections. Both channels use single-ended outputs and share internal frequency compensation. This architecture is appropriate for general-purpose voltage amplification, impedance buffering, comparison, instrumentation, and feedback-control blocks where moderate bandwidth and supply flexibility are more important than low-noise precision or rail-to-rail output operation. Typical applications include sensor-signal conditioning, industrial transducer interfaces, analog control loops, audio preamplifier stages, voltage buffering, and general instrumentation. In a 2 x 2 mm DFN package, the device can reduce board area in designs that can accommodate a land pattern without an exposed thermal pad and maintain adequate copper and assembly process capability. Design with the LM2904Q2T by verifying input common-mode range, output swing, supply current, and capacitive-load stability against the operating point. Keep sensitive-input and feedback routes short, place input and output bypass capacitors close to their associated supply pins, and follow the manufacturer's layout and soldering guidance for the small-pitch DFN footprint. This page combines the exact LM2904Q2T ordering information with electrical characteristics, package constraints, application guidance, a same-package replacement assessment, and practical selection criteria. It also distinguishes confirmed drop-in compatibility from broader functional equivalents so engineers can make footprint-aware design decisions without treating similar amplifier specifications as guaranteed interchangeability.

Texas Instruments LM2904QD is an automotive-grade, dual operational amplifier with a 26 V maximum supply rating, 700 kHz gain-bandwidth product, and an 8-terminal gull-wing SOP package. The device contains two general-purpose amplifier sections, allowing one package to support two independent analog signal paths while reducing board area in automotive electronic-control systems. An operational amplifier is an analog amplifier IC that uses high open-loop gain to amplify voltage differences between its non-inverting and inverting inputs. The LM2904 belongs to the broader hierarchy of operational amplifier, voltage-feedback amplifier, analog IC, and semiconductor. Its dual-channel configuration allows two amplifier sections to be used for signal conditioning, buffering, sensing, or feedback-control functions without adding a second package. The LM2904QD is identified as an automotive temperature-grade variant. Its 26 V supply capability accommodates automotive-style power rails, while the 700 kHz gain-bandwidth product supports general-purpose closed-loop signal amplification at moderate frequencies. The dual architecture also reduces component count in systems that need two equivalent amplifier channels. Operation from a single positive supply is a defining family characteristic, although common-mode range, output swing, offset, and noise figures should be checked against the manufacturer datasheet for the exact operating conditions. The 8-terminal SOP package uses gull-wing leads and a rectangular body, making LM2904QD suitable for conventional through-hole board assembly rather than a compact surface-mount land pattern. Because the automotive suffix denotes a qualified ordering configuration, engineers should confirm the exact qualification, temperature range, marking, and production-test requirements in the Texas Instruments ordering information before release to manufacturing. Typical applications include automotive sensor interfaces, actuator-driver feedback paths, battery-monitoring circuits, instrumentation signal conditioning, and low-frequency control loops. In each case, the two amplifier sections can process complementary or independent signals. The 700 kHz bandwidth is generally more relevant to low-bandwidth sensing and feedback than to high-speed signal processing, so applications requiring wide-band precision or rail-to-rail output should be reviewed separately. The principal design consideration is error budget: input offset voltage, input bias current, common-mode input range, output voltage swing, supply current, and stability with the selected feedback network determine practical accuracy. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs should be biased according to the manufacturer’s recommended configuration. PCB layout should preserve a low-impedance ground return and avoid long feedback traces. This page combines the Texas Instruments family specifications, package details, drop-in alternatives, and implementation guidance into an engineering-focused reference. It also identifies which parameters require confirmation in the full manufacturer datasheet, helping designers distinguish confirmed LM2904QD characteristics from application-specific design requirements.

Texas Instruments LM2904QDRG4 is a dual general-purpose operational amplifier designed for industrial and automotive control systems. The device contains two independent, internally frequency-compensated amplifiers, operates from a single supply as high as 26 V, and supports dual supplies of ±13 V. Each channel has a gain-bandwidth product of 700 kHz and a slew rate of 0.3 V/µs, while the typical supply-current drain is 0.7 mA. The specified package is the narrow-body 8-SOIC, supplied tape and reel. An operational amplifier is an analog signal-conditioning IC that uses high open-loop gain and negative feedback to amplify voltage differences. The dual-amplifier configuration places two independent amplifiers in one package, making it useful within the hierarchy of op amp, dual op amp, analog IC, and integrated circuit. Common uses include sensor conditioning, voltage amplification, comparison, and control-loop stages where broad supply-voltage tolerance is valuable. The LM2904QDRG4 is specified for single-supply operation up to 26 V and dual-supply operation at ±13 V. Its common-mode input range includes ground, which allows the device to process signals near the lower supply rail. The internally frequency-compensated architecture simplifies closed-loop design, while the 700 kHz gain-bandwidth product supports general-purpose signal paths rather than high-speed precision applications. The two channels provide independent operation, allowing one channel to perform signal amplification while the other handles feedback, comparison, or monitoring. A 0.3 V/µs slew rate governs large-signal response, and the 0.7 mA typical supply-current drain supports low-power control designs. The 8-SOIC footprint is widely used for industrial and automotive printed-circuit boards, although engineers should verify the exact pin arrangement and exposed thermal requirements in the manufacturer datasheet. Typical applications include automotive sensor interfaces, industrial control loops, low-level signal conditioning, actuator-driver feedback networks, and general dual-amplifier signal paths. The 26 V supply capability is particularly useful when a circuit must operate from a nominal 24 V industrial rail while retaining tolerance for transient excursions, provided the absolute maximum limits are respected. When designing a replacement, verify the channel pinout, supply limits, common-mode range, output-swing limits, and required package dimensions before changing the PCB. Decoupling capacitors should be placed close to the supply pins, and sensitive layouts should minimize parasitic capacitance between input and output nodes to preserve stability. This page combines manufacturer specifications, package information, same-family replacement guidance, comparison parameters, and practical circuit-design considerations. It is intended to help engineers identify an exact-footprint alternative, compare practical constraints, and design the LM2904QDRG4 into industrial or automotive control electronics.

LM2904QDRQ1 - Dual 26V 700kHz Op Amp AEC-Q100 | TI

The Texas Instruments LM2904QDRQ1 is an automotive-grade, dual operational amplifier qualified to AEC-Q100, operating from a single supply of 3V to 26V (or dual supplies plus/minus 1.5V to plus/minus 13V) with a 700 kHz gain-bandwidth product in an 8-pin SOIC (D) package rated -40C to +125C. An operational amplifier (op amp) is a high-gain differential-input voltage amplifier and a fundamental analog building block within the signal-chain hierarchy: op amp -> amplifier IC -> analog/mixed-signal IC -> semiconductor. A dual op amp integrates two independent amplifiers in one package, cutting board space and BOM cost for multi-channel signal conditioning. Key features include a low 500 uA supply current per amplifier, a common-mode input range that includes ground (enabling true single-supply operation), internal frequency compensation, and output short-circuit protection. ESD protection exceeds 500 V per MIL-STD-883 Method 3015 and 200 V on the machine model, per the TI datasheet. Technically, the bipolar process yields a typical 2 mV input offset voltage (7 mV max) and 20 nA typical input bias current. The 0.3 V/us slew rate and 700 kHz GBW suit low-frequency sensor and control loops; the output swings close to the negative rail but is not rail-to-rail. Operation remains stable with moderate capacitive loads. Typical applications include automotive sensor signal conditioning (temperature, pressure, position), current sensing, active filters, DC motor control, and battery management front-ends, where the 26V rating allows direct operation from a 12V automotive battery rail with load-dump headroom. Design tip: decouple VCC with a 0.1 uF ceramic close to pin 8, keep the input common-mode below VCC-1.5V, and buffer high-impedance sources to limit offset errors. For new automotive designs requiring 36V ratings and tighter offset, consider the next-generation LM2904B-Q1 family.

The automotive-compliant construction identifies it for applications requiring a higher-reliability general-purpose amplifier. Its MSOP-8 package supports compact PCB layouts, while the -13 ordering suffix identifies tape-and-reel production packaging. The manufacturer describes the LM2904Q family as automotive-compliant dual and quad operational amplifiers, with industry-standard pinouts and green mold compound. The LM2904Q and LM2904AQ devices are offered in SO-8, TSSOP-8, and MSOP-8 packages. This package compatibility gives engineers a familiar circuit implementation, while the dual topology simplifies circuits requiring one signal-conditioning channel and one feedback or drive channel. Typical uses include low-side current sensing, transducer amplification, active filtering, comparator-style signal conditioning, and general industrial control. In current-sensing applications, the amplifier compares a scaled voltage across a shunt with a reference. In sensor interfaces, it amplifies small voltage changes around a common-mode level. In active filters, its gain-bandwidth behavior and open-loop gain define the operating point when combined with external resistors and capacitors. For a new layout, verify the MSOP-8 pin assignment and orient the exposed package according to the manufacturer datasheet before assigning input, output, supply, and feedback connections. Decoupling capacitors should be placed close to the supply pins, and sensitive input traces should be kept away from switching nodes and high-current paths. The 36 V rating is a maximum operating limit rather than a recommended supply condition.

LM2904QPWRG4Q1 - 26V Dual Op Amp | Texas Instruments

Texas Instruments LM2904QPWRG4Q1 is an automotive-grade, dual general-purpose operational amplifier with two independent amplifiers, a 26 V maximum supply rating, and a 700 kHz gain-bandwidth product. The device is packaged in an 8-pin TSSOP (PW) package and is qualified to AEC-Q100 specifications for automotive applications. An operational amplifier is a high-gain, frequency-compensated analog building block used to amplify sensor signals, control feedback loops, buffer voltage references, and perform general signal conditioning. The LM2904 belongs to the dual operational-amplifier hierarchy and combines low supply-current consumption with a wide common-mode input range that includes ground, making it suitable for single-supply systems operating near the lower rail. The dual configuration provides two amplifiers in one package, reducing board area when a design needs matched general-purpose stages. Key characteristics include a 700 kHz gain-bandwidth product, a 0.3 V/µs slew rate, and a typical low supply-current drain of 0.7 mA per amplifier. Its AEC-Q100 qualification supports automotive-grade applications where temperature robustness and production quality requirements are important. Internally, the device contains two independent, high-gain, frequency-compensated amplifiers. Frequency compensation allows operation without external compensation, while the ground-referenced common-mode capability is valuable for sensing small signals produced by sensors, resistive dividers, and single-supply analog circuits. The 26 V maximum rating also provides headroom for industrial and automotive supply environments. Typical uses include low-side current sensing, sensor-signal conditioning, actuator feedback, automotive interface electronics, and general dual-amplifier signal conditioning. Because both channels are independent, one package can support two related functions, such as signal amplification and an active filter, without requiring separate single amplifier packages. Designers should maintain input and output voltage limits, account for input common-mode range, and provide stable feedback-network layouts around the device. Decoupling capacitors should be placed close to the supply pins, while sensitive input and feedback nodes should be kept away from switching-current paths. The automotive qualification does not replace application-level validation of transient immunity, noise, and thermal performance.

LM2904QS-13 - 36V Dual Op Amp, 1.1MHz | Diodes Incorporated

Diodes Incorporated LM2904QS-13 is an automotive-compliant dual operational amplifier packaged in an 8-pin SO-8 package. The device operates from a 36 V maximum supply, provides two amplifier channels, and combines a 1.1 MHz gain-bandwidth product with 100 dB open-loop gain. Its 500 uA quiescent current and 20 nA typical input bias current suit low-power analog signal chains that require higher voltage tolerance than conventional low-voltage amplifier families. An operational amplifier, commonly called an op amp, is a high-gain differential amplifier whose closed-loop behavior is defined primarily by external feedback components. Within the semiconductor hierarchy, the LM2904QS-13 belongs to the operational amplifier, analog amplifier IC, and power-management-supporting signal-conditioning categories. It can amplify sensor outputs, implement active filters, buffer voltage references, and perform general-purpose analog conditioning where a wide supply range and dual-channel integration are useful. Key characteristics include two independent amplifier circuits, a 36 V maximum supply, 1.1 MHz unity-gain bandwidth, 100 dB open-loop gain, 500 uA quiescent current, and a typical input bias current of 20 nA. These characteristics make the part appropriate for industrial control, instrumentation, automotive electronics, and appliance applications where two channels can reduce component count and board space. The automotive-compliant LM2904Q family is also manufactured with green mold compound as standard. The LM2904 architecture supports single-supply operation as well as conventional dual-supply operation when negative supply voltage is available. Input and output common-mode limits must remain within the operating boundaries stated in the manufacturer datasheet. Because the amplifier is intended for broad-voltage applications, designers should distinguish the 36 V maximum supply rating from the usable output-swing and input-common-mode ranges; those ranges are not determined by the maximum supply alone. Typical applications include sensor conditioning, current-loop receivers, active low-pass filters, audio and communications blocks, automotive electronics, industrial control modules, and general analog signal-conditioning boards. Two integrated channels are especially useful when a design requires closely related positive and negative signals, such as differential sensor outputs, dual-axis sensing, or paired audio paths. Local decoupling and careful trace routing remain important because high-gain amplifiers can amplify noise, oscillation, and unintended feedback caused by poor layout. For stable operation, place the power-supply bypass capacitor close to the supply pins, keep feedback components compact, and route output signals away from high-impedance input nodes. Avoid placing long copper traces beneath the amplifier unless the layout specifically supports the intended thermal and electrical behavior. Check the complete pin assignment and exposed-package details against the manufacturer datasheet before finalizing a footprint or assembling a prototype. This product page combines the LM2904QS-13 package and electrical identity, verified manufacturer documentation, same-footprint replacement guidance, application-specific engineering notes, and a parameter comparison intended to accelerate component selection. The primary decision factors are SO-8 footprint compatibility, supply voltage, unity-gain bandwidth, input bias current, quiescent current, and automotive qualification requirements.

LM2904QTH-13 - Dual 36V Automotive Op Amp | Diodes Incorporated

Diodes Incorporated LM2904QTH-13 is a dual general-purpose operational amplifier designed for automotive electronics. It contains two independent high-gain amplifiers in an 8-pin TSSOP package, operates from a single supply up to 36 V or from dual supplies up to ±18 V, and is identified as AEC-Q100 compliant. Key characteristics include a 700 kHz gain-bandwidth product, 0.3 V/µs slew rate, 7 mV input-offset voltage, 250 nA input-bias current, and approximately 700 µA supply current. An operational amplifier is a high-gain analog signal-conditioning IC that compares an input voltage with a feedback reference and drives its output to reduce the difference between them. The LM2904 dual-amplifier configuration belongs to the operational-amplifier family within analog ICs and analog signal-processing semiconductors. Its two channels may be used independently for signal conditioning, voltage comparison, feedback control, or other general-purpose analog functions. The LM2904QTH-13 combines relatively wide supply-voltage tolerance with low quiescent current and automotive-compliant construction. A 36 V maximum supply makes it useful in systems operating from industrial or automotive batteries after appropriate transient and protection design. Its 700 kHz gain-bandwidth product is adequate for low-to-moderate-frequency signal paths, while the 0.3 V/µs slew rate affects how quickly the output can follow large voltage changes. The 40 mA output-current figure and 250 nA input-bias current define important loading and input-stage constraints. The two amplifiers provide flexibility within one compact package, reducing component count in dual-channel circuits. Each channel has its own differential input and output pins, allowing simultaneous or independent operation. Because the device is intended for general-purpose amplification, its offset voltage, input-bias current, bandwidth, and output-drive capabilities must be checked against the target signal amplitude, source impedance, load, noise requirements, and stability conditions. Typical applications include automotive sensor conditioning, actuator and valve-driver feedback, battery-powered instrumentation, industrial control modules, current monitoring, and low-frequency signal amplification. In battery-powered systems, the approximately 700 µA supply-current characteristic helps limit standing power when both channels are operating at low utilization. For high-impedance sensors, the 250 nA input-bias current should be compared with the sensor's effective source impedance and resulting offset error. The main design consideration is maintaining stability with the output load and compensation network selected for the target feedback topology. Keep sensitive input traces away from power paths and output nodes, provide local supply bypassing, and account for automotive supply transients at the board interface. The TSSOP-8 outline also requires thermal analysis when both channels drive demanding loads at elevated ambient temperature. This product page combines the manufacturer and distributor characteristics for the LM2904QTH-13 with package, replacement, application, and design guidance.

An operational amplifier is a high-gain, differential-input analog amplification component used to compare or amplify voltage signals. Within the electronics hierarchy, the LM2904 belongs to the operational-amplifier family, which sits within analog amplifier ICs and broader semiconductor signal-conditioning products. Its two-channel configuration allows one device to implement two related analog functions while reducing the number of components required on a circuit board. The manufacturer datasheet identifies the LM2902 and LM2904 series as low-input-offset-voltage amplifiers designed for single power-supply operation over a wide voltage range, with split-supply operation also possible. The operating-temperature characterization extends from -40°C to +125°C. The standard green mold compound, industry-standard pinout, and SO-8 packaging support use in conventional industrial, instrumentation, control, and signal-conditioning equipment. The 1.1 MHz gain bandwidth product makes the device appropriate for low-frequency amplification rather than high-speed signal processing. Its 100 dB open-loop gain provides substantial nominal gain before feedback and saturation limits are considered. The 20 nA input bias-current listing is also relevant when the source impedance is high, because bias-current error can become significant relative to the input voltage being measured. Typical uses include transducer-signal conditioning, feedback networks in control systems, active filtering, sensor amplification, and general-purpose analog signal conditioning. Two amplifiers in one package are useful when a design needs an inverting stage and a non-inverting stage, two sensor channels, or an amplifier paired with a comparator-like buffer function. Designers should verify input common-mode range, output swing, output-current capability, offset voltage, and supply-current limits in the manufacturer datasheet before finalizing a new board. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs must be biased so that both output stages remain in a defined operating state. This product page combines the manufacturer family data with practical application guidance, a same-package family alternative, and engineering-focused selection criteria. It is intended to help engineers determine whether the LM2904S-13 is appropriate for a low-frequency, dual-amplifier design before moving to detailed electrical verification and PCB implementation.

STMicroelectronics LM2904ST is a low-power dual operational amplifier packaged in an 8-pin MiniSO package. It contains two independent, internally frequency-compensated amplifiers, allowing one device to implement two separate analog signal-processing channels. The LM2904 family is intended for general-purpose applications where a dual amplifier, low power consumption, and straightforward circuit implementation are more important than low-noise or high-speed performance. An operational amplifier is an active semiconductor device that compares two input voltages and drives its output to amplify the difference between them. In a closed-loop configuration, negative feedback causes the output to follow the intended circuit function with very high input impedance and relatively low output impedance. The LM2904 belongs to the operational-amplifier hierarchy, where it sits below precision amplifiers, rail-to-rail amplifiers, and high-speed amplifiers while remaining appropriate for industrial control, sensor conditioning, audio, and general instrumentation. The LM2904ST provides two amplifier channels in one package, reducing component count and PCB space compared with two separate single-channel amplifiers. Its internally implemented frequency compensation simplifies circuit design by eliminating the need for external compensation components in standard closed-loop applications. Because both channels are independent, the device can support different signal paths, provided the designer observes the common power-supply and grounding requirements. The target LM2904ST is a standard general-purpose dual amplifier in the MiniSO-8 format. The STMicroelectronics LM2904 family also includes other package and performance options, so engineers should compare electrical ratings, temperature range, supply limits, input common-mode range, output swing, and automotive qualification before treating another family member as a drop-in replacement. The exact electrical limits and environmental classifications should be confirmed in the manufacturer datasheet for the selected ordering code. Typical uses include low-frequency sensor signal conditioning, control-loop amplification, active filtering, audio preamplification, transducer interfaces, and general buffer stages. In such circuits, the LM2904ST provides two independently usable channels while keeping the implementation compact. Its internal compensation makes conventional inverting, non-inverting, summing, and differential amplifier configurations straightforward, although output loading, source resistance, stability margins, and the input common-mode range still require careful review. For a new layout, place the device close to the signals it processes, maintain a low-impedance return path to the supply ground, and decouple the supply pins locally. Avoid sensitive-source connections next to the output or supply pins, because parasitic coupling can increase offset and distortion.

The device contains two independent high-gain amplifiers, supports a 700 kHz bandwidth, and is designed for operation from a single supply or from split supplies. The LM2904 family provides a practical choice for signal conditioning, feedback control, and analog circuit designs requiring two amplifiers in one package. An operational amplifier, commonly called an op amp, is a high-gain DC-coupled analog amplifier whose behavior is controlled by feedback around the device. The LM2904 combines two independent amplifier channels in one package, reducing board area compared with two separate single-amplifier devices. Its 8-pin TSSOP package supports compact surface-mount assemblies and exposes supply, input, and output connections for each channel. The most prominent specified characteristics are the two-amplifier configuration, 700 kHz bandwidth, and supply capability extending to ±18 V, equivalent to a 36 V total span. The device is categorized as a standard general-purpose amplifier and is designed for both single-power-supply and split-supply operation. Its architecture also targets low input-offset voltage, making it relevant to closed-loop amplifier and comparator-style signal-processing applications when configured appropriately. The LM2904 series combines independent high-gain operational amplifiers with a broad supply-voltage range. Because the two channels are independent, one channel can process a sensor signal while the other performs an active filter, level conversion, or feedback function. Common-mode and output-voltage limitations still depend on the selected supply voltages, so every analog signal path must remain inside the amplifier’s valid input and output ranges. Typical uses include low-frequency instrumentation, buffered sensor interfaces, audio preamplification, analog gain stages, and dual-axis control loops. The 700 kHz bandwidth is most appropriate for general-purpose signal paths rather than high-speed video, RF, or precision data-conversion applications. Split-supply operation can simplify bipolar signal handling, while single-supply operation may require input and output biasing around the midpoint of the supply. Designers should use the manufacturer’s pin-description and typical-application information to establish channel assignments, bypass-capacitor placement, and acceptable output-load conditions. Decouple each supply rail close to the device, keep feedback paths short, and verify that input common-mode voltage and output swing remain valid over the full supply range and temperature range intended for the design. This page organizes the key device characteristics, practical application guidance, verified pricing references, pin-location information, and same-footprint replacement options.

Typical applications include 0–5 V or 0–10 V industrial sensor interfaces, low-level transducer amplification, analog alarm and threshold circuits, active low-pass filters, and general control-signal conditioning. It may also be used in battery-powered instrumentation where the selected operating point must balance signal bandwidth against power drain. Split-supply operation is useful for bipolar sensor signals or analog stages that require both positive and negative swing around ground. When designing around the LM2904VDMR2, verify input and output voltage limits at the selected supply voltage and load. Input and output decoupling should be placed close to the device, and unused amplifier channels must be configured according to the manufacturer’s recommended stable operating conditions.

Texas Instruments LM2924MX is a low-power bipolar analog IC that combines an operational-amplifier function with voltage-comparator operation in an 8-pin SOIC package. It is identified as a single-function transducer-amplifier circuit, is designed for industrial-temperature use, and is supplied in a rectangular surface-mount SOP package. The LM2924MX therefore serves as a compact analog signal-conditioning component for systems that require amplification and threshold detection in one package. An operational amplifier is a voltage-controlled analog amplifier whose open-loop gain is made large enough to amplify small signals accurately when negative feedback is applied. A voltage comparator compares one input voltage with another and changes its output state when a threshold is crossed. Together, these functions form part of the broader linear and mixed-signal IC hierarchy, where they support sensor conditioning, control loops, signal detection, and industrial interface circuits. The LM2924MX combines three notable product attributes. First, its bipolar construction places it in the classical family of analog amplifier ICs. Second, its single-function analog-circuit architecture supports compact implementation of transducer and signal-conditioning paths. Third, the 8-pin surface-mount SOIC package permits automated assembly while reducing board area compared with larger through-hole packages. Its industrial temperature grade also positions it for equipment operating beyond typical commercial-temperature conditions. LM2924MX is identified as a low-power operational amplifier and voltage comparator. This dual operating role allows the same device to amplify a low-level analog signal and evaluate whether that signal has crossed a defined reference level. In feedback-based configurations, the amplifier behavior supports closed-loop gain; in open-loop threshold service, the comparator behavior provides a digital indication of an analog condition. Exact gain-bandwidth, input-offset, supply-voltage, and output-current limits should be confirmed from the manufacturer datasheet before final circuit sizing. Typical uses include bridge or resistive-transducer signal conditioning, industrial sensor interfaces, low-level control-signal amplification, threshold detection, and alarm-generation circuits. The 8-pin SOIC footprint is suitable for compact analog boards where a surface-mount part is preferred and where signal conditioning must be placed close to the sensor or source to minimize susceptibility to interference. Designers should determine the allowable supply range, input common-mode range, output swing, input-offset voltage, noise, and comparator propagation behavior from the manufacturer datasheet. Decoupling capacitors should be placed close to the supply pins, while sensitive input routing should avoid switching nodes and high-current return paths. Feedback resistors and any hysteresis network must be evaluated for the required gain, offset, and threshold stability. This product page consolidates the exact package, temperature-grade, circuit-type, and lifecycle information for LM2924MX, maps suitable analog applications, and provides engineering guidance for layout, compensation, and sourcing.

The LM293AD operates from 2 V to 36 V and provides a response time of approximately 300 ns. Its common-mode input range includes ground, and its differential input range can equal the maximum-rated supply voltage of ±38 V according to the manufacturer product information. Open-collector outputs support wired logic, pull-up arrangements, level translation, and compatibility with TTL, MOS, and CMOS systems. Each comparator section compares an inverting input with a non-inverting input. When the non-inverting input is higher, the corresponding open-collector output transistor turns off; when the inverting input is higher, the output transistor turns on. An external pull-up resistor is required for conventional open-collector operation. The two channels share the supply pins but retain separate input and output pins. Typical uses include industrial sensor interfaces, battery monitoring, power-supply fault detection, overvoltage protection, relay or LED indication, and control systems that compare an analog voltage against a reference. The wide operating supply range is useful when the comparator must tolerate industrial transients while operating from a higher-voltage rail. Designers should verify input and output absolute maximum ratings, provide adequate pull-up resistors, maintain a valid common-mode range, and account for output-current limits when several wired-open-collector outputs share a bus. Because the outputs can sink current but cannot source it independently, external pull-ups determine the high logic voltage and rise-time behavior. This product page combines manufacturer specifications, verified distributor listings, same-package replacement guidance, and practical comparator-design notes. It helps engineers evaluate the LM293AD for industrial threshold detection, protection, monitoring, and open-collector interface designs without confusing it with open-drain parts that use different output structures.
