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

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. Review the pin-description table and recommended operating conditions in the manufacturer datasheet before final PCB release or substitution to another dual amplifier.

LM2904PWRG4

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

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.

LM2904QD

LM2904QD - Dual 26V 700kHz Automotive Op Amp | Texas Instruments

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.

LM2904QDRG4 - Dual 26 V 700 kHz Op Amp | Texas Instruments

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

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 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.

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. It highlights practical distinctions among same-footprint alternatives and identifies the electrical details that require confirmation against the current manufacturer datasheet before production release.

LM2904S-13 - Dual 1.1MHz Op Amp, 100dB Gain | Diodes

The Diodes Incorporated LM2904S-13 is a dual general-purpose operational amplifier packaged in an 8-pin SO package. It provides two independent amplifier channels, a listed gain bandwidth product of 1.1 MHz, a listed open-loop gain of 100 dB, and input bias current of 20 nA. The device is intended for single-supply or split-supply operation across industrial temperature conditions. 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.

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. This product overview combines the manufacturer family information, package identity, pin assignment, sourcing considerations, and drop-in-replacement guidance to support faster engineering selection and PCB planning.

LM2904TH-13 - Dual 700 kHz Op Amp | Diodes Incorporated

Diodes Incorporated LM2904TH-13 is a dual general-purpose operational amplifier in an 8-pin TSSOP package. 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. It also distinguishes documented LM2904 family choices from alternatives that would require a different package or different electrical capabilities, helping engineers narrow a redesign without overlooking PCB compatibility.

LM2904VDMR2 - Dual 3-32V Op Amp for Industrial Control

The onsemi LM2904VDMR2 is a dual general-purpose operational amplifier with a 3 V to 32 V supply range, 1 MHz gain-bandwidth product, and 8-MSOP package. Designed for low power consumption, the device accepts single-supply or split-supply operation, while its common-mode input voltage range can extend to ground or VEE. It is suited to industrial signal-conditioning, transducer, and analog-control systems. An operational amplifier is a voltage-gain building block used to amplify small signals, buffer sensors, compare voltages, and implement active analog filters. The dual LM2904 family combines two amplifiers in one package, reducing board area compared with separate single amplifiers. Its ability to operate from a single positive supply or from split positive and negative rails gives it broad utility in both grounded-signal systems and bipolar analog environments. Key features include low power drain, a 1 MHz gain-bandwidth product, and a common-mode input range that extends to ground or VEE. The 3 V to 32 V operating range supports both conventional 5 V and 24 V industrial systems when the total supply remains within the rated range. The 8-MSOP surface-mount package also supports compact, high-density analog boards while providing adequate lead spacing for automated assembly and inspection. The LM2904 architecture derives from the circuit design used in onsemi's quad operational-amplifier family. It is intended for general-purpose applications where low power consumption and flexible supply configurations are more important than precision, rail-to-rail input/output performance, or the bandwidth of modern CMOS amplifiers. Because the input common-mode range can reach ground or VEE, the device can process signals near the lower supply rail when correctly biased. 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. Avoid relying on rail-to-rail behavior, and account for input offset and bias-current errors when designing high-accuracy signal chains. This product page consolidates the confirmed supply, bandwidth, package, and application characteristics with drop-in replacement analysis, package comparison, and practical circuit guidance. It helps engineers distinguish genuine footprint-compatible options from amplifiers that are only functionally similar before committing a new board revision.

The onsemi LM2904VDR2G is a dual, general-purpose operational amplifier with a 1 MHz gain-bandwidth product, 0.6 V/µs slew rate, and operation from single or split supplies in an 8-SOIC package. It is designed for instrumentation, signal conditioning, buffer amplification, and general analog control applications where two amplifiers are required in one package. An operational amplifier is an analog integrated circuit that uses high open-loop gain and negative feedback to amplify a voltage difference. The LM2904 family belongs to the operational-amplifier hierarchy, with the LM358 family representing one-half of a quad amplifier. Its common-mode input range extends to ground or VEE, allowing useful operation in single-supply circuits where the input signal approaches the negative supply rail. Key features include two amplifier circuits per package, a 1 MHz gain-bandwidth product, a 0.6 V/µs slew rate, and a specified operating voltage range of up to ±16 V, equivalent to 32 V across the supply rails. The low-power design supports both single-supply and split-supply operation. The standard 8-SOIC package also simplifies assembly in designs that do not require a high-performance precision amplifier. The LM2904 architecture is intended for general-purpose amplification rather than rail-to-rail input or output operation. Its common-mode input behavior reaches ground or VEE, making it particularly useful for circuits powered from a positive rail and ground. As with any feedback amplifier, stable operation depends on suitable compensation, output loading, source impedance, and the selected gain network. Typical uses include buffering sensor outputs, amplifying low-level analog signals, conditioning potentiometer inputs, driving moderate loads, building active filters, and providing general-purpose gain stages in industrial or embedded systems. Two amplifiers in one SOIC package can also simplify layouts where matched general-purpose stages are needed. When designing around the LM2904, check the common-mode input range and output swing at the intended load rather than assuming rail-to-rail behavior. Place input and feedback components close to the device, provide adequate bypassing near the supply pins, and verify stability at the lowest planned gain. The manufacturer datasheet should guide compensation, load capability, and absolute maximum ratings. This product page combines the exact LM2904VDR2G package and electrical identity with practical design guidance, pin-level information, verified source links, and a package-matched replacement comparison. These engineering details help buyers distinguish the dual general-purpose amplifier from single-amplifier, automotive-qualified, and other LM-family variants before committing to a PCB design.

The device provides two independent amplifiers, automotive qualification under AEC-Q100, and operation over a -40°C to +125°C ambient-temperature range. An operational amplifier is a high-gain, high-impedance analog signal-processing component that compares its differential input voltage with a feedback network to produce an amplified output. The dual-amplifier configuration places two amplifiers in one package, reducing board area in applications such as sensor conditioning, current-loop signal processing, filtering, and general-purpose analog amplification. LM2904-Q1 belongs to the operational-amplifier, amplifier IC, and analog IC hierarchy within semiconductor signal-conditioning electronics. The LM2904VQPWRQ1's key attributes are its dual-circuit architecture, 26 V maximum total supply rating, 700 kHz gain-bandwidth product, and ability to operate across a 3 V to 32 V supply range. AEC-Q100 qualification supports its use in automotive electronic systems, while the extended -40°C to +125°C ambient-temperature range addresses industrial temperature requirements. Low supply current and ESD protection are additional features identified in the family datasheet. The amplifier family is designed for general-purpose operation rather than high-speed precision signal paths. Its 700 kHz bandwidth is suitable for moderate-frequency conditioning, while the automotive qualification and wide supply operating range suit electronic control units, sensor interfaces, actuator drivers, battery-powered systems, and industrial measurement modules. Users should confirm output-swing, input-common-mode, offset, and stability limits against the specific operating conditions in the manufacturer datasheet before finalizing a design. Typical applications include low-side current sensing in automotive electronic control units, conditioning resistive sensor signals, amplifying sensor and transducer outputs, active filtering, and general voltage amplification. The two amplifier sections can process related signal paths while sharing one supply package, which simplifies power distribution and reduces component count compared with two discrete single amplifiers. PCB design should provide a stable ground reference, short feedback paths, appropriate input-biasing, and decoupling close to the supply pins. Because automotive environments can contain electrical transients and ESD events, system-level protection and validation remain essential even though the amplifier family includes ESD-protection features. Confirm pin orientation and signal names against the manufacturer pin-configuration table before layout release. This page organizes the automotive dual operational amplifier's electrical limits, package information, design considerations, application guidance, and verified drop-in alternatives.

LM2924M Low-Power Op Amp/Comparator | Texas Instruments
LM2924M

LM2924M Low-Power Op Amp/Comparator | Texas Instruments

Texas Instruments LM2924M is a low-power dual-purpose analog IC containing two independent building blocks: a high-gain, internally frequency-compensated operational amplifier and a precision voltage comparator. The device is packaged in an 8-pin SOIC and is identified as an industrial-temperature-grade component. This combination allows one package to provide signal amplification and threshold detection without using separate amplifier and comparator packages. An operational amplifier is a voltage amplifier whose closed-loop gain is established by an external feedback network. A voltage comparator compares two input voltages and switches its output according to their relationship. The LM2924M combines these complementary functions in a single analog device, placing it in the operational-amplifier and comparator hierarchy while supporting transducer, sensing, control, and signal-conditioning applications. The internally frequency-compensated operational amplifier is designed to operate without an external compensation capacitor, simplifying implementation in basic gain configurations. Its comparator section provides an independent decision-making channel, allowing the two internal circuits to monitor or condition separate signals simultaneously. Because the amplifier and comparator are independent building blocks, their inputs and outputs can be used for different stages of a system. The National Semiconductor datasheet describes the LM2924M as a low-power operational amplifier and voltage comparator for precision voltage-amplification and related analog signal-processing needs. The 8-pin SOIC package provides a compact surface-mount format for industrial equipment, embedded controls, instrumentation interfaces, and mixed analog-digital circuit boards. Typical applications include transducers whose weak outputs require voltage amplification, sensor interfaces requiring a defined switching threshold, industrial control loops, and analog monitoring subsystems. The dual internal architecture can reduce board area when a design needs both continuous analog amplification and discrete threshold detection. For PCB implementation, assign the supply, ground, input, and output pins according to the manufacturer pin-description table and preserve the recommended input/output operating conditions. Confirm signal ranges, output states, stability requirements, and temperature limits against the device datasheet before connecting external transducers or logic interfaces. This page combines the device architecture, package details, sourcing guidance, verified replacement constraints, and practical application guidance.

LM2924MX - Low-Power Amplifier/Comparator | Texas Instruments
LM2924MX

LM2924MX - Low-Power Amplifier/Comparator | Texas Instruments

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. It also distinguishes confirmed drop-in replacements from merely similar amplifier or comparator families so that PCB reuse decisions remain technically defensible.

LM293AD - Dual Differential Comparator, 2-36V | Texas Instruments
LM293AD

LM293AD - Dual Differential Comparator, 2-36V | Texas Instruments

Texas Instruments LM293AD is an industrial-grade dual differential comparator with two independent comparison channels, a 2 V to 36 V supply range, rail-to-rail input operation, and open-collector/open-drain outputs. The device is packaged in an 8-pin SOIC and is designed for sensing and control applications involving wide input and output voltage conditions. A differential comparator is an integrated circuit that compares two input voltages and changes its output state according to their relationship. Its two channels can monitor thresholds, detect crossings, implement window functions, or generate control signals. The LM293 belongs to the comparator hierarchy within analog interface ICs, where it bridges analog sensing and digital control logic. 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.

The onsemi LM293AM is a dual differential comparator designed for single-supply operation up to 36 V or dual-supply operation up to ±18 V, and it is available in an 8-pin SOIC package. Its differential inputs allow two voltages to be compared, while the open-collector output structure supports flexible interface and pull-up arrangements in control, sensing, and protection circuits. A differential comparator is an analog integrated circuit that compares two input voltages and changes its output state according to their relationship. The dual configuration provides two independent comparators in one package. When used with an external pull-up, an open-collector output can drive TTL, MOS, or CMOS-compatible circuitry while also allowing wired logic, level translation, or system reset behavior. The LM293AM belongs to the comparator hierarchy within amplifier and interface ICs. Key features include single-supply operation to 36 V, dual-supply operation to ±18 V, a typical low-current drain of 800 µA, and a typical input bias current of 25 nA. The device can compare input voltages near ground potential and is compatible with multiple logic families. Its low input bias current helps reduce source-loading effects in high-impedance sensing networks, while the wide supply range supports industrial and automotive-style control environments. The LM293AM uses open-collector outputs rather than push-pull outputs. This architecture provides a useful advantage when a comparator output must remain inactive until an external pull-up supplies the required logic-high voltage. It also supports open-wired signal arrangements, but every application must include the appropriate pull-up resistor and verify that the resulting rise time is acceptable. The operating common-mode range, differential input limits, output sink capability, and timing behavior should be checked against the manufacturer datasheet for the selected manufacturer version. Typical applications include industrial control systems, power-supply supervision, motor and solenoid protection, battery monitoring, sensor-threshold conditioning, window or level detection, and general-purpose logic interfaces. The dual comparator arrangement is particularly useful when one circuit monitors two related thresholds or when an enable function and a fault signal can be implemented with the two channels in a compact footprint. For PCB design, place the device so that sensitive input traces remain away from switching nodes and output pull-up routing. Keep input and output paths separate to reduce feedback through supply or board-level coupling. Confirm the logic-high level, output rise time, input common-mode range, supply decoupling requirements, and operating temperature range before releasing the design for production. This page combines manufacturer-family operating limits, package details, sourcing guidance, replacement analysis, and practical PCB considerations to support faster component selection. Review the complete pin assignment and electrical characteristics in the LM293AM datasheet before layout, particularly when the same circuit must accommodate multiple LM293-family variants.

LM293AN - Dual Open-Collector Comparator | STMicroelectronics

The STMicroelectronics LM293AN is a low-power dual voltage comparator with two independent comparator channels, open-collector and open-drain outputs, and an 8-DIP package. The device is designed for general-purpose signal comparison and can operate from a single supply over a wide voltage range, while split-supply operation is also possible. Its listed rail-to-rail input designation, ground-referenced common-mode capability, and TTL, MOS, and CMOS output compatibility make it suitable for threshold detection, level translation, and analog-control systems. A voltage comparator is an integrated circuit that compares two input voltages and produces a logic-level indication of their relationship. In this role, LM293AN belongs to the comparator IC hierarchy within analog and mixed-signal semiconductors. Each of its two channels can evaluate a non-inverting input against an inverting input, allowing one package to perform two related comparisons while keeping channel operation independent. The LM293 family documentation identifies low power consumption as a defining characteristic and specifies input-offset voltage as low as 2.0 mV maximum for the associated two-comparator family. Open-collector outputs provide flexibility when the destination device requires a pull-up resistor, particularly in wired logic, relay-driver, and legacy digital-interface applications. The outputs are also listed as compatible with TTL, MOS, and CMOS logic families. Operation from a single supply is central to the device design. The common-mode input range includes ground, while the differential input voltage can extend to the maximum-rated supply voltage of ±38 V according to TI's LM293 family information. The 8-DIP mechanical format provides through-hole access to the two comparator channels, power, ground, and output connections. Typical uses include industrial control thresholds, sensor-interface decisions, window comparators, oscillator and timer designs, and general logic level conditioning. The two independent channels can also implement a larger comparator arrangement through external resistor networks. Open-collector outputs make pull-up selection an important part of the interface design because the output cannot directly drive a logic high without this external support. The main design consideration is that open-collector outputs require correctly selected pull-up resistors and adequate logic-level rise time at the driven node. Supply decoupling, input-source impedance, output load, and common-mode headroom should be reviewed against the application's operating conditions.

According to the Texas Instruments LM293 product page, the device is a dual differential comparator in an industrial-grade family; detailed electrical limits are not supplied in the verified excerpts and therefore remain marked for data completion. A comparator is an analog signal-conditioning IC that compares two input voltages and produces a logic-level output indicating which input is higher. A differential comparator belongs to the broader comparator, amplifier, and analog interface hierarchy, while the LM293D is specifically a low-power, dual-channel comparator for embedded and control applications. Its two independent channels allow simultaneous comparison of two signal pairs, provided the device operates within the manufacturer-rated common-mode and supply limits. The verified TI page states that the LM293 family supports wide supply-voltage operation, including systems using split power supplies. TI also states that the B-version is a drop-in replacement for LM293, LM393, and LM2903; however, the provided data does not establish that every related suffix is electrically identical for every use condition. The LM293D listing identifies open-collector/open-drain and rail-to-Rail output characteristics, which are important when interfacing with pull-up-based digital systems.

LM293DG - Dual Precision Comparator, 2-36V, SOIC-8 | onsemi

The onsemi LM293DG is a dual independent precision voltage comparator in an 8-pin SOIC package, built for single or split supply operation across a 2 V to 36 V supply range. Each channel offers an input offset voltage as low as 2.0 mV, a 1.3 microsecond response time, and a supply current of about 400 microamps per channel, with an open-collector (open-drain) output stage compatible with TTL, MOS and CMOS logic. A comparator is a differential amplifier used as a simple decision element: it compares two input voltages and switches its output state when the non-inverting input rises above the inverting input. The comparator category sits above discrete transistor switches in the signal-conditioning hierarchy and below instrumentation amplifiers in the analog IC family, sitting in the amplifier IC / signal conditioning control group of parts such as op amps, references and sensor interface ICs. The LM293 series is distinguished from general-purpose comparators by its low input offset voltage, wide supply range and ability to operate with the common-mode input range extending to ground, which makes it a strong fit for single 5 V or single 12 V systems where the signal of interest lives near the negative rail. The two channels are fully independent, each with its own pair of inputs and output. The open-collector output stage is the key architectural feature: the output transistor sinks current but never sources it, so an external pull-up resistor to the supply or logic rail is required to establish a valid high level. That architecture permits level shifting to any voltage up to the maximum supply, wired-AND bus tying, and direct drive of relay or solenoid drivers without a buffer stage. Because the output stage is a bipolar NPN transistor, output sink current is limited compared with modern CMOS comparators. Typical applications include overvoltage and undervoltage protection in linear and switching power supplies, battery and pack monitoring window comparators, motor stall and over-current detection, industrial sensor thresholding, and automotive-style sensor protection. The SOIC-8 package with 1.27 mm lead pitch supports both through-hole assembly and standard surface mount reflow, and the -25 C to +85 C ambient range covers industrial and consumer equipment. When designing with the LM293DG, always fit a pull-up resistor on each output and check the sink current against the pull-up value and the load. If your design needs rail-to-rail input operation, push-pull outputs, or a supply below 2 V, a CMOS comparator is the better choice; if it needs low offset with wide supply and open-drain flexibility, the LM293DG remains a proven, low-cost choice. This page consolidates manufacturer specifications, drop-in replacement candidates, pin-level detail and practical design guidance so that you can qualify the LM293DG for an existing board revision without redrawing the footprint.

Keep pull-up resistors close to open-drain outputs, and account for input common-mode range and supply polarity in both single-supply and split-supply systems. The LM293DR is not a power semiconductor, so SOA data is not applicable.
