LM2903QDGKRQ1

LM2903QDGKRQ1 - Dual 36V Automotive Comparator | Texas Instruments

The Texas Instruments LM2903QDGKRQ1 is an AEC-Q100 Grade 0 and Grade 1 automotive dual differential comparator with open-collector outputs, operating from 3 V to 36 V and supplied in an 8-pin VSSOP package. The device provides two independent comparison channels, a common supply range of 3 V to 36 V, and input common-mode operation extending to the supply rails. According to the TI LM2903-Q1 product page, the LM2903-Q1 family is designed for cost-sensitive automotive and industrial systems requiring high-voltage tolerant inputs and open-collector outputs. A comparator is an analog integrated circuit that evaluates two input voltages and produces a digital output indicating whether the non-inverting input is above or below the inverting input. Within the broader hierarchy, the LM2903-Q1 is a differential comparator, a general-purpose analog IC, and a member of the power-management and signal-conditioning semiconductor category. Its open-collector output structure allows several comparator outputs to be wired together for wired-AND operation and requires an external pull-up resistor for normal logic-level operation. Key characteristics include dual-channel operation, a 36 V maximum supply capability, and open-collector outputs suitable for automotive battery-powered systems. The AEC-Q100 Grade 0 and Grade 1 qualification supports demanding automotive environments, while the wide input voltage range reduces the need for separate input protection in many 12 V, 24 V, and 36 V system architectures. The 8-pin VSSOP package also supports compact PCB layouts where space is limited. The LM2903-Q1 architecture is designed for general-purpose threshold detection rather than high-speed waveform discrimination. Its differential input stage allows sensing of small analog changes, and the open-collector outputs can directly pull up a logic bus, drive a relay driver, or interface with automotive transceiver inputs. The open-collector configuration also provides wired-AND behavior when multiple comparator channels share a pull-up resistor. Typical applications include automotive battery monitoring, overvoltage and undervoltage detection, window or door sensing, sensor conditioning, and industrial control systems. In battery systems, the wide supply tolerance supports operation across load dump and automotive electrical-environment conditions when paired with appropriate protection. In control logic, two independent channels can monitor separate thresholds or implement a window comparator using external resistor networks. When designing the PCB, route the comparator inputs away from switching nodes and high-current return paths because input offset voltage can make nearby interference appear as a false state transition. Place the pull-up resistor close to the open-collector output and verify that its value keeps the logic rise time within the receiving device's limits. Automotive designs should also include the transient-protection components required by the complete vehicle electrical system rather than relying on the comparator alone for surge suppression. This page consolidates the verified package, voltage, output, qualification, and lifecycle information with application guidance, comparison parameters, and design notes that support faster component selection and PCB implementation.

LM2903QDRQ1

LM2903QDRQ1 - 36V Automotive Dual Comparator | Texas Instruments

The Texas Instruments LM2903QDRQ1 is an AEC-Q100-qualified automotive dual differential comparator with two independent comparison channels, a 2 V to 36 V single-supply operating range, and open-collector outputs in an 8-pin SOIC package. It is designed for high-voltage industrial and automotive systems where two independent comparator channels are required in a compact package. A differential comparator is an analog integrated circuit that compares the voltage at its inverting input with the voltage at its non-inverting input and changes its output state when the input difference crosses a defined threshold. The comparator belongs to the broader hierarchy of analog ICs, signal-conditioning ICs, and semiconductor devices. Its open-collector architecture allows the output to be pulled up to a system-compatible logic voltage rather than being limited to the IC supply rail. Key electrical characteristics include a typical input offset voltage of 2 mV, a typical input bias current of 25 nA, and a supply current of 0.4 mA per comparator. Each channel provides one push-pull-compatible input stage and an open-collector output that is compatible with TTL, MOS, and CMOS logic families. The single-supply operating range is 2 V to 36 V, while operation from dual supplies is possible when the total supply difference is between 2 V and 36 V. The LM2903-Q1 family combines a wide supply range with low supply current and AEC-Q100 Grade 0 and Grade 1 options. These characteristics make it suitable for sensing circuits connected to higher-voltage buses than those commonly handled by low-voltage mixed-signal comparators. The open-collector outputs also simplify wired-interface and level-shifting arrangements when an external pull-up resistor is used. Typical applications include automotive battery and power-system monitoring, industrial control systems, motor and solenoid feedback circuits, window or lighting controllers, overcurrent and overvoltage detection, and general-purpose threshold sensing. Two channels in one package reduce board area when independent comparison functions are required. The main design consideration is the open-collector output. Every output requires a pull-up resistor to the desired logic rail, and the pull-up must be sized against the output sink current and expected switching rate. Designers should also verify the input common-mode range at the selected supply voltage before committing the circuit to automotive or industrial rail conditions.

Typical uses include automotive battery monitoring, overvoltage and undervoltage detection, fan-speed control, sensor conditioning, power-supply supervision, and industrial control systems. The dual architecture also allows both halves to operate independently, although their input common-mode behavior and output pull-up network must be checked against the system requirements. When laying out the board, keep comparator inputs away from switching nodes and route the ground reference directly to the device ground pin. Choose the external output pull-up for the required logic family, account for the open-collector sink-current limit, and validate the design across the full temperature range. This page combines manufacturer specifications, package details, verified listing information, drop-in alternatives, and practical design guidance for faster component selection.

LM2903QS-13

LM2903QS-13 - 36V Dual Precision Comparator | Diodes Incorporated

The Diodes Incorporated LM2903QS-13 is a dual precision voltage comparator designed for operation from a single supply or split power supplies. Its headline ratings include a 36 V maximum supply voltage, 2 mV input offset voltage, 25 nA input bias current, 0.6 mA supply current, and 5 nA input offset current. The device is packaged in an 8-pin SOIC and is qualified to AEC-Q100 for automotive applications. A voltage comparator is an analog interface IC that evaluates two input voltages and switches its output when one input becomes higher than the other. Within the semiconductor hierarchy, a comparator belongs to the amplifier IC family, supports signal conditioning, and is frequently used to bridge low-level analog measurements to digital logic. The LM2903 contains two independent comparators, allowing one package to monitor two thresholds or perform two independent decisions. The low input offset and bias-current characteristics support precise threshold decisions when signals originate from sensors, dividers, or low-level analog stages. The common-mode input range includes ground, a useful property for single-supply systems whose signals remain near the lower rail. Open-collector outputs also allow the two channels to be connected together for wired-AND operation and permit external pull-up resistors to establish the logic-high voltage independently of the comparator supply. The LM2903 architecture emphasizes low power consumption and broad supply compatibility rather than high-speed comparator performance. According to the Diodes Incorporated datasheet, the series supports single-supply operation over a wide voltage range and split-supply operation as well. This makes it suitable for industrial, automotive, and embedded systems where a sensing element compares a variable voltage against a reference before driving a control, fault, or sequencing circuit. Typical applications include supply sequencing, battery and power-system threshold detection, sensor signal conditioning, window-comparator implementations, overvoltage and undervoltage protection, and general digital-logic interfacing. Two independent channels can implement a two-threshold system, compare two sensor signals, or provide one always-enabled channel and one conditionally monitored channel. The 8-pin SOIC footprint is convenient for conventional surface-mount assembly. The principal design consideration is the open-collector output. Each output requires a pull-up resistor to the appropriate logic supply, and the selected resistor must satisfy the output sink-current and rise-time requirements. Inputs should also remain within their specified common-mode and differential ranges, while supply decoupling should be placed close to the device to limit switching-induced disturbance. This product record combines the LM2903QS-13 electrical identity, automotive-grade package information, family-level replacement context, and application-focused design guidance. It helps engineers identify the correct SOIC-8 part, understand its threshold-measurement role, and compare it with same-footprint dual-comparator options before finalizing a PCB or BOM revision.

LM2903S-13

LM2903S-13 - Dual 36V Differential Comparator | Diodes

Diodes Incorporated LM2903S-13 is a dual differential comparator in an 8-pin SOIC package, with a 36 V maximum supply rating, 20 mA output current capability, and 25 nA input bias current rating. It contains two independent comparators, allowing one package to provide two separately controlled threshold-detection or level-shifting channels. A differential comparator is an analog integrated circuit that compares two input voltages and changes its output state according to their relationship. Within the broader hierarchy of comparator IC, voltage comparator, analog IC, and semiconductor, the LM2903S-13 is intended for general-purpose signal conditioning, threshold detection, and logic-interface applications. Its dual-channel architecture improves board utilization while keeping the two channels electrically independent. Key features include a 36 V maximum total supply voltage, operation from a single supply or split supplies, and an input common-mode range that includes ground. The open-collector outputs are designed to interface with TTL, MOS, and CMOS logic. Each comparator can drive an external pull-up network, making the device useful when a wired-AND function or level translation is required. The stated 25 nA input bias current supports applications where input bias effects must be controlled. The LM2903 family uses an open-collector output architecture rather than a push-pull or rail-to-rail CMOS output. When the output transistor is off, the output voltage is set by the pull-up resistor and its connected supply. When the output transistor is on, the output approaches ground while remaining within the device's output-current capability. This architecture provides flexibility in interface voltage, but it also requires an external pull-up resistor and suitable attention to pull-up current. Typical applications include two-threshold monitoring, zero-cross detection, sensor-signal conditioning, relay or solenoid drive interfaces, window comparators, and general digital logic level translation. The device can also support dual-polarity sensing when powered from split supplies. Its 8-pin SOIC package is convenient for conventional through-hole assembly and hand rework, although modern high-density designs may prefer a smaller surface-mount package when one is qualified. For reliable operation, keep the total supply voltage within the 36 V rating and observe the absolute maximum input and output limits listed in the manufacturer datasheet. Place the pull-up resistor close to the output net, maintain a continuous ground return, and account for the open-collector output's rise time, which is determined by output capacitance and pull-up resistance rather than by a dedicated push-pull driver. This product page combines the LM2903S-13 device identity, package details, manufacturer-family information, sourcing references, pin-compatible alternatives, and application-oriented design guidance. It is structured to help engineers evaluate the comparator electrically before deciding whether the 8-pin SOIC implementation matches the assembly, protection, interface, and lifecycle requirements of the target design.

LM2903TH-13

LM2903TH-13 Dual Differential Comparator | Diodes

Diodes Incorporated LM2903TH-13 is a dual differential comparator designed for general-purpose analog signal comparison, with two independent comparator channels and an 8-pin TSSOP package. The device operates from 2 V to 36 V, accepts input voltages spanning approximately ±18 V in the dual-supply configuration, and provides a maximum input offset voltage of 7 mV. These characteristics position it for industrial control, sensor interfacing, voltage-threshold detection, and general analog decision-making circuits. A comparator is an analog integrated circuit that compares two input voltages and produces a logic-level output indicating which input is higher. A differential comparator evaluates the voltage difference between its inverting and non-inverting inputs. This function is placed within the hierarchy of comparator integrated circuits, analog signal-processing ICs, semiconductor devices, and electronic control systems. Unlike a general-purpose operational amplifier used primarily for linear amplification, a comparator is optimized for fast, decisive output-state transitions. The LM2903 family provides two channels in one package, reducing component count and PCB space in dual-threshold applications. Its 2 V to 36 V supply capability supports operation from low-voltage analog systems through substantially higher industrial voltage ranges. The 7 mV maximum input offset specification limits the input difference that can be recognized as a deliberate transition, making the device suitable for threshold monitoring when board-level signal integrity and input conditioning are properly controlled. The dual differential architecture allows two independent comparisons within one IC. Each channel can monitor a sensor signal against a reference, supervise a supply rail, or establish an upper and lower control boundary. Its wide operating-voltage range is especially useful where input signals may exceed the nominal supply of a low-voltage controller. The 8-TSSOP package also supports compact surface-mount layouts, although thermal performance and unused-channel handling remain important design considerations. Typical uses include industrial motor-control logic, power-supply supervision, temperature-sensor interfaces, battery monitoring, overvoltage detection, and general-purpose threshold switching. For dual-polarity sensing, the comparator can operate from single or dual supplies. For a single-supply design, the output reference and input signal levels must remain compatible with the supply voltage and the logic thresholds of the following digital device. PCB design should keep sensitive comparison inputs away from switching nodes and high-current return paths. Place input-referenced components close to the corresponding pins, maintain a stable ground reference, and account for input bias current when using high-source-impedance sensors. If only one comparator channel is required, verify the manufacturer's guidance for the unused channel so that it does not introduce unstable behavior or excess switching activity. This product page combines the LM2903TH-13 identification, package information, technical specifications, sourcing workflow, verified drop-in alternatives, and practical comparison guidance. It is intended to help engineers determine whether the dual comparator's voltage range, offset limit, pin compatibility, and surface-mount format match a specific analog-control design.

LM2903VN - Dual 36V Open-Collector Comparator | onsemi

The onsemi LM2903VN is a dual, general-purpose voltage comparator with open-collector outputs, rail-to-rail input capability, and a supply-voltage rating of 2 V to 36 V. The device is offered in an 8-pin PDIP package and is qualified for automotive applications with an operating ambient-temperature range of -40°C to +125°C. Each half of the IC contains an independent comparator, allowing two threshold or switching functions to be implemented in one package. A voltage comparator is an analog integrated circuit that compares an input voltage with a reference voltage and changes its output state when the relationship between the voltages changes. Within the broader semiconductor hierarchy, a comparator belongs to the interface and signal-conditioning IC family. It converts a small voltage relationship into a logic-level indication that can be used by control systems, protection circuits, sensing equipment, and industrial automation systems. The LM2903VN is identified as a low-offset-voltage, low-power dual comparator. Its open-collector output architecture requires an external pull-up resistor when the output is used as a wired logic signal. This arrangement permits several open-collector outputs to share a common bus when their pull-up network is designed correctly. The rail-to-rail input designation indicates operation across the full input range covered by the device, while the 2 V to 36 V supply rating supports operation from low-voltage logic systems through higher-voltage industrial applications. Automotive qualification and the -40°C to +125°C ambient-temperature range make the LM2903VN relevant to temperature-tolerant control and monitoring circuits. The dual configuration can reduce component count when a design requires independent positive and negative threshold decisions, two sensor-limit channels, or complementary logic outputs. Because the two comparators are independent, they can also be used with different input networks, reference voltages, and output pull-ups within the ratings of the device. Typical design roles include supply sequencing, overvoltage indication, sensor-threshold detection, window monitoring, and general digital control. The 8-pin PDIP package favors through-hole assembly and conventional prototyping. PCB layout should keep input and feedback traces short, place the input bypass capacitor close to the supply pins, and route high-current or switching-node copper away from the comparator inputs to reduce false transitions. This page combines the manufacturer-device identification, package and operating information with engineering guidance for threshold design, open-collector interfacing, automotive use, and PCB implementation. It also provides comparison and replacement guidance intended to help engineers evaluate board-level alternatives without overlooking supply-voltage, common-mode, output-stage, and package differences.

LM2903VQDRQ1 - 36V Dual Automotive Comparator | Texas Instruments

Texas Instruments LM2903VQDRQ1 is a dual differential comparator rated for a 2 V to 36 V supply, operating from -40 °C to +125 °C in an 8-pin SOIC package. The device provides two independent comparison channels with open-collector outputs compatible with TTL, MOS, and CMOS logic. It is qualified to AEC-Q100 Grade 0 and Grade 1 for automotive applications. A comparator is a differential amplifier whose output indicates whether its non-inverting input is above or below its inverting input. The LM2903VQDRQ1 belongs to the comparator hierarchy within analog and mixed-signal integrated circuits. Its high-voltage supply tolerance and automotive qualification make it suitable for monitoring 12 V and 24 V vehicle electrical systems, where input signals can exceed conventional logic supply levels. The LM2903VQDRQ1 supports single-supply operation from 2 V to 36 V or dual-supply operation from ±1 V to ±18 V. Each channel includes an inverting input, a non-inverting input, and an open-collector output. The open-collector architecture requires an external pull-up resistor and permits the output to be pulled up to a logic voltage different from the comparator supply. Supply-current drain is specified as 0.4 mA, supporting low-power monitoring systems. The differential input-voltage range extends to the maximum-rated supply voltage, while the common-mode input range includes ground. These characteristics support threshold detection, overvoltage and undervoltage detection, sensor conditioning, and automotive signal monitoring. The open-collector outputs can sink external-device current when the comparison state is active, while the pull-up network establishes the inactive high state. A typical propagation delay of approximately 1.3 µs is appropriate for general-purpose control rather than high-speed edge detection. Typical uses include battery-pack protection, automotive power-rail supervision, industrial control thresholds, window and sensor-limit comparisons, and interface logic for open-collector buses. In vehicle systems, the wide supply range allows a comparator to operate directly from protected battery-related rails when the preceding circuit provides suitable transient protection. In process-control equipment, the comparator can supervise a transducer signal and provide a pulled-up logic indication to a controller. Design the pull-up resistor to balance output rise time, switching current, power consumption, and the sink-current rating of the open-collector output. Keep the two comparison channels independent even when they share the supply pins. Provide stable supply decoupling close to the device, route sensitive input traces away from switching nodes, and use the manufacturer's pin-description table when assigning PCB tracks. Automotive implementations should also include the transient-protection and layout measures required by the completed vehicle interface. This product page combines the exact ordering information, manufacturer specifications, pin arrangement, drop-in replacement analysis, application guidance, and engineering design notes needed to evaluate the LM2903VQDRQ1 before it is assigned to a PCB or placed on a bill of materials.

LM2903VQPWRG4Q1

LM2903VQPWRG4Q1 - 30V Dual Comparator | Texas Instruments

The Texas Instruments LM2903VQPWRG4Q1 is an automotive dual differential comparator with two independent open-collector channels, a 30 V maximum supply voltage, and an 8-pin TSSOP package. The LM2903VQPWRG4Q1 supports single-supply or dual-supply operation and is qualified to AEC-Q100 Grade 0 and Grade 1 for automotive electronics. A comparator is an analog integrated circuit that compares two input voltages and changes its output state when the non-inverting input rises above the inverting input. The differential comparator belongs to the broader comparator, analog IC, and semiconductor hierarchies. It is commonly used for threshold detection, overvoltage and undervoltage monitoring, sensor conditioning, and converting analog levels into digital logic signals. The device provides lower offset voltage, higher supply-voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2 kV ESD performance than earlier LMx93-family devices. Typical input offset voltage is no more than 7 mV at 25°C, supply current is 0.4 mA per comparator, and nominal response time is 1.3 microseconds. Its open-collector outputs allow wired logic, pull-up resistors, and level translation to the supply voltage used by the receiving logic. Each channel has independent noninverting and inverting inputs, so the two comparators can monitor separate signals or implement two thresholds. The common-emitter open-collector output sinks current from an external pull-up and naturally goes to a high-impedance state when the comparator is inactive. Because the output stage is not push-pull, output rise time depends on the pull-up resistor, total bus capacitance, and leakage current rather than only on internal drive strength. Typical uses include automotive battery monitoring, sensor threshold detection, industrial control inputs, overvoltage and undervoltage protection, and signal conditioning between analog sensors and digital controllers. Single-supply operation simplifies power architecture, while dual-supply operation allows inputs and output pull-ups to reference different voltage domains. The wide 30 V supply range also accommodates 12 V and 24 V automotive electrical environments when the absolute maximum ratings and transient requirements are respected. For PCB design, keep the comparator inputs and power-ground return paths compact, connect the exposed-decoupling route to a low-impedance ground plane, and place the output pull-up resistor near the driven logic input. Avoid routing sensitive input traces beside power outputs or long pull-up traces. Input protection may be required in external automotive connectors, and production designs should validate the complete system for conducted noise, ESD events, supply transients, and open-collector pull-up compatibility. This page combines exact ordering information, automotive qualification details, drop-in comparator choices, application-specific engineering guidance, and a parameter comparison to help engineers select and implement the LM2903VQPWRG4Q1 correctly.

LM2903VQPWRQ1

LM2903VQPWRQ1 - Dual 36V Automotive Comparator | Texas Instruments

The Texas Instruments LM2903VQPWRQ1 is a dual general-purpose differential comparator in an 8-pin TSSOP package, qualified to AEC-Q100 Grade 0 and Grade 1 for automotive applications. It provides two independent open-collector outputs, operates from single or dual supplies, and supports supply-voltage differences from 2 V to 36 V when used with dual supplies. The typical supply-current drain is 0.4 mA per comparator. A comparator is an analog integrated circuit that evaluates a voltage at its non-inverting input against a voltage at its inverting input and switches its output according to the polarity of that difference. The LM2903 family belongs to the broader hierarchy of differential comparator, analog comparator, linear integrated circuit, and semiconductor. Its open-collector outputs allow the output stage to be pulled up to a local supply or logic rail, providing flexibility for wired-AND arrangements and direct interfacing with TTL, MOS, or CMOS-compatible circuitry. The V-enhanced LM2903-Q1 family is designed for cost-sensitive applications requiring wide supply tolerance, low supply-current drain, and automotive qualification. According to the manufacturer product page, the device offers improved low-offset voltage, higher supply-voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2 kV ESD performance compared with earlier LM293, LM393, and LM2903 families. The improved 2 kV ESD capability is especially relevant to chassis-connected and cable-driven automotive systems. Typical uses include battery monitoring, threshold detection, overvoltage and undervoltage protection, window comparators, motor-control interfaces, and signal conditioning. Because each half of the device operates independently, one package can implement two unrelated comparison functions. This reduces component count while preserving separate inputs and outputs for each channel. For PCB design, keep the two comparator channels away from high-current switching paths and high-impedance input traces where practical. Place input-referenced components close to their associated pins, provide an uninterrupted ground return, and use pull-up resistors on both open-collector outputs. Confirm the pull-up voltage, output-sink current, input common-mode range, and supply limits against the manufacturer datasheet before fixing the external component values.

LM2903XK

LM2903XK - Dual Open-Drain Comparator | Runic Technology

Runic Technology LM2903XK is a dual-channel, general-purpose voltage comparator with open-drain outputs, supplied in an 8-pin SOIC package. The device is intended for industrial control and consumer-electronics circuits that compare two input voltages and require a digital, low-side output for interfacing with pull-up-based logic systems. Its dual-channel architecture allows two independent threshold comparisons in one package. A voltage comparator is a semiconductor that evaluates the relationship between two voltages and changes its output state when one input crosses the other. The comparator category belongs to the broader signal-conditioning and interface-IC hierarchy, where an analog voltage decision is converted into a logic-compatible event. The LM2903XK open-drain output can support wired logic, system monitoring, threshold detection, and control functions when paired with an appropriate pull-up resistor. The LM2903XK provides two comparator channels, open-drain output structures, and an 8-SOIC package identified as SOIC-8 with a 0.154-inch, 3.90 mm width. PartGenie classifies the device for industrial-control and consumer-electronics applications. Its listed environmental-handling classification is MSL 3 for 168 hours, while its compliance records identify RoHS3 compliance and no REACH impact. Because the output is open drain, each channel can pull its output node to a defined logic-low state but cannot actively drive a logic-high state. A pull-up resistor or compatible pull-up network is therefore required. This arrangement provides useful flexibility because the output can be referenced to a supply selected by the system designer, while multiple open-drain outputs can share a bus when the electrical conditions and device limits permit. Typical uses include monitoring a power rail against a reference, detecting sensor thresholds, generating reset or fault signals, comparing two analog signals, and implementing simple control loops. The dual-channel format is especially useful when a system requires two related decisions, such as an upper-limit detector and a lower-limit detector, without using separate single-channel packages. The primary PCB considerations are pin orientation, input common-mode limits, output pull-up values, and the voltage and current ratings of the open-drain nodes. Designers should use the manufacturer datasheet pin-description table and electrical characteristics before finalizing input ranges, output sink-current limits, supply limits, and decoupling requirements. A local ground-reference arrangement is important for stable comparator behavior. This product page consolidates the LM2903XK function, package information, compliance records, verified source links, and application guidance. It also identifies confirmed package-related alternatives and clearly separates them from unverified or differently packaged options so that engineers can assess PCB compatibility before making a replacement decision.

Key characteristics include a wide single-supply operating range of 2 V to 36 V, dual-supply operation from ±1 V to ±18 V, and very low supply current of 0.4 mA. The typical input bias current is 25 nA, while the typical input offset current is ±5 nA. The open-collector outputs support wired-AND arrangements and require an external pull-up when the comparator must drive a logic input. Automotive-grade versions of this device family are associated with AEC-Q100 qualification. The two internal comparators are electrically independent, allowing separate signal paths within the same package. Rail-to-rail input behavior and low input bias current are useful when sensing source voltages that vary close to either supply rail. The low supply current also reduces power consumption in battery-powered systems, although propagation delay and output pull-up selection remain important when switching speed is critical. Typical applications include automotive battery and power-rail monitoring, industrial sensor threshold detection, overvoltage and undervoltage protection, window-comparator circuits, and logic-level translation between analog sensing nodes and digital control circuits. Its 2 mm × 2 mm DFN8 package supports compact board layouts when adequate copper area and controlled assembly are available. Designers should verify the complete pin assignment and exposed-pad requirements in the manufacturer datasheet before layout. Place input and output components close to their associated pins, provide a suitable pull-up for each open-collector output, and use stable reference sources when threshold accuracy matters. Confirm that signal amplitudes, common-mode range, supply limits, and automotive qualification requirements suit the target circuit. This product page consolidates the manufacturer electrical characteristics, package details, verified sourcing links, practical application guidance, and drop-in-replacement assessment. It also highlights the key limitation that a replaceable device must match both the 8-DFN footprint and pin behavior, rather than merely offering similar comparator performance.

LM2904AM8-13

LM2904AM8-13 - Dual 700 kHz Op Amp | Diodes Incorporated

Diodes Incorporated LM2904AM8-13 is a dual general-purpose operational amplifier with a 700 kHz gain-bandwidth product, supplied in an 8-MSOP package. The device contains two independent, high-gain amplifiers and supports operation from a single supply or split supplies. Its specified operating range extends to ±18 V, equivalent to a total supply voltage of 36 V. This combination of dual-channel operation, wide supply capability, and surface-mount packaging makes the LM2904AM8-13 suitable for general-purpose signal conditioning across industrial, instrumentation, analog control, and embedded systems. An operational amplifier is a high-gain differential amplifier that uses negative feedback to control gain, filtering, amplification, buffering, or analog signal conversion. The dual-amplifier configuration reduces the number of active devices and board area needed when two independent analog channels are required. The LM2904AM8-13 belongs to the operational-amplifier hierarchy, where it sits below precision instrumentation amplifiers and above general-purpose discrete analog signal-conditioning functions. The LM2904 series is identified as a general-purpose amplifier family with very low input-offset voltage relative to many older general-purpose op amps. The two channels share an 8-MSOP package while retaining independent inputs and outputs. A 700 kHz gain-bandwidth product supports general-purpose closed-loop operation at moderate signal frequencies, and the ±18 V supply capability provides useful headroom for circuits using higher signal amplitudes. These characteristics make the part appropriate where low cost, channel density, and supply-voltage flexibility are more important than rail-to-rail input or output operation. The common operating topology places positive and negative feedback around each amplifier, setting closed-loop gain through external resistors. Because the device is intended for broad industrial signal conditioning, designers should verify the required input common-mode range, output swing, output-current capability, input-bias behavior, and stability against the exact operating conditions. The manufacturer datasheet provides the electrical limits and characteristic curves needed to select suitable feedback resistors, bypass capacitors, and external load conditions. Typical uses include sensor-interface conditioning, low-frequency active filters, differential-input stages, transducer amplifiers, analog control loops, and general instrumentation. Industrial data-acquisition systems can use one channel for signal conditioning while using the second channel for biasing, monitoring, or an auxiliary gain stage. The device is also appropriate for compact embedded analog subsystems where an 8-MSOP package reduces board footprint compared with two separate single-amplifier packages. When laying out the circuit, place bypass capacitors close to the supply pins and route feedback components close to their associated amplifier inputs and outputs. Avoid long parallel feedback traces, particularly when operating near the device's 700 kHz gain-bandwidth limit. Check whether the input source can develop voltages outside the specified common-mode range, because general-purpose op amps are not automatically rail-to-rail devices. This product page combines the LM2904AM8-13 operating characteristics with package guidance, application engineering notes, and a parameter-by-parameter comparison framework. It is intended to help engineers identify design constraints quickly while preserving the distinction between published device specifications and application-specific engineering judgments.

The device operates from a 36 V maximum supply, provides two amplifier channels, and is specified for 500 uA supply current, 20 nA input bias current, and 100 dB open-loop gain. Its 8-MSOP package supports compact analog signal-conditioning layouts while retaining the industry-standard dual-op-amp pin arrangement described for the LM2904Q family. An operational amplifier, or op amp, is a high-gain analog amplifier used to amplify voltage differences, buffer sensors, drive external loads, and implement active filters. The LM2904 belongs to the broader general-purpose amplifier hierarchy, which includes dual and quad operational amplifiers used in signal-chain, instrumentation, and control applications. Its wide supply range makes it useful where signal levels and supply conditions vary substantially. The headline characteristics make the LM2904AQM8-13 appropriate for low-power signal conditioning. A 36 V maximum supply expands the usable operating envelope, while 500 uA supply current limits the power burden of dual-channel circuits. The 20 nA input bias current reduces loading on high-impedance sources, and 100 dB open-loop gain provides useful amplification when feedback establishes the closed-loop gain. The LM2904Q family uses industry-standard pin arrangements and is available in multiple small-outline packages. The M8-13 ordering option places this dual amplifier in an 8-MSOP. For conventional non-unity-gain operation, feedback networks define the closed-loop response, while input common-mode and output-swing limits must remain within the datasheet operating envelope. Decoupling should be placed close to the supply pins to reduce supply-borne noise. Typical uses include low-side current monitoring, transducer and sensor interfaces, buffered analog measurements, active filtering, and general-purpose signal conditioning in automotive or industrial equipment. The dual configuration reduces board area when two independent analog channels are required, although crossover distortion is important when similar signals are amplified simultaneously at high output levels. Designers should verify input bias current, input offset voltage, output swing, common-mode range, and stability requirements against the complete operating conditions. Avoid relying on rail-to-rail operation unless the applicable LM2904 datasheet explicitly confirms the required input or output range. Decoupling capacitors, grounding, and feedback-component placement remain important even though the amplifier itself has a low supply current of 500 uA. This product page consolidates the verified order information, package details, technical attributes, application guidance, and qualified drop-in comparison points. It is designed to help engineers determine whether the LM2904AQM8-13 fits a compact, dual-channel automotive signal-conditioning design and to identify the closest pin-compatible alternatives before a board-level substitution.

The Diodes listing also identifies a 100 dB open-loop gain metric and approximately 500 uA supply-current class, which make the amplifier practical for low- and moderate-frequency industrial and automotive circuits. The LM2904AQ family is identified by Diodes Incorporated as automotive compliant. The S suffix in LM2904AQS-13 identifies the SO-8 package option, while -13 identifies the supplier packaging format. This dual-channel configuration allows one package to implement two independent amplifier stages, reducing component count when a board requires signal buffering, differential amplification, active filtering, or two sensing channels. Typical applications include 5 V and 12 V sensor interfaces, automotive transponder and battery-management signal conditioning, industrial process-control inputs, active low-pass filters, and general dual-amplifier boards. The wide 36 V supply capability is particularly useful where signal nodes can experience industrial transients or automotive battery-related voltages, provided the design keeps every pin within the device's absolute maximum ratings. Design the feedback network for the intended closed-loop bandwidth, keep input and output signals within the common-mode range, and bypass the supply pins close to the package. Decoupling capacitors should be placed at the IC rather than at the power-source entry point. If the amplifier drives capacitive loads, add an isolation resistor and verify stability and output-current margin in the final board layout. This page combines package, electrical, automotive-compliance, cross-reference, and replacement information with practical guidance for dual op-amp layouts. It helps engineers distinguish the exact automotive SO-8 device from broader LM2904 variants, package variants, and functional alternatives that may require different qualification or footprint review.

The device is supplied in an 8-pin SO package and is characterized for operation from -40°C to +125°C. An operational amplifier is a high-gain analog signal-conditioning IC used to amplify voltage differences, buffer sensor outputs, implement active filters, and serve as the input stage of control and measurement systems. In the broader semiconductor hierarchy, the LM2904 belongs to the amplifier IC family, specifically low-power general-purpose operational amplifiers designed for single or dual supply operation. The two-channel configuration lets one package support independent signal paths while reducing board area and the number of required components. A 100 dB open-loop gain supports accurate amplification of small signals, while the 1.1 MHz gain-bandwidth product provides useful bandwidth for common low-frequency and moderate-frequency analog tasks. The stated 20 nA input bias current is particularly relevant when the source impedance is high. The 3 V to 36 V supply span permits operation from conventional single-supply rails through higher industrial supply voltages. Its specified 1 mV input offset supports applications where input-referred error must be controlled relative to the signal level. The -40°C to +125°C characterization provides a broad temperature range for industrial equipment, instrumentation, automotive-adjacent circuitry, and other systems requiring stable operation over extended environmental conditions. Typical uses include transducer-signal conditioning, active audio and control paths, low-frequency filter stages, sensor amplification, and general dual-amplifier circuits. The SO-8 package is suitable for conventional surface-mount assembly, and the manufacturer states that the LM2904/LM2902 family uses green mold compound as standard. When laying out a circuit, keep input and feedback paths short, provide stable bypassing close to the supply pins, and confirm common-mode and output-swing limits at the selected supply voltage and load.

LM2904ATH-13

LM2904ATH-13 - Dual General-Purpose Op Amp | Diodes Incorporated

The Diodes Incorporated LM2904ATH-13 is a dual, general-purpose operational amplifier packaged in an 8-pin TSSOP. It is intended for single-supply or dual-supply signal-conditioning applications and uses the widely recognized LM2904 amplifier architecture. The device operates from a single supply up to 36 V or from split supplies totaling 36 V, equivalent to ±18 V, while providing two amplifiers in one package. The LM2904 family is intended for general-purpose amplifier, comparator, and voltage-control applications where economy, wide supply-voltage operation, and straightforward PCB implementation are important. An operational amplifier is an analog building block that amplifies the difference between two input voltages. Within the broader semiconductor hierarchy, this product is a general-purpose operational amplifier, or op amp, used in analog signal chains, feedback-control loops, sensor interfaces, and buffer stages. The dual configuration allows one IC to implement two independent amplifier channels, reducing board area and simplifying designs that compare, amplify, filter, or condition two signals. The LM2904ATH-13 provides two independent channels with high open-loop gain and approximately 700 kHz gain-bandwidth performance. Its general-purpose positioning makes it suitable for audio preamplification, transducer conditioning, DC signal amplification, and low-to-moderate-frequency control applications. The 8-pin TSSOP package supports compact surface-mount layouts, while the tape-and-reel suffix identifies the production packing format. Exact input-offset, input-bias-current, output-swing, noise, and temperature limits must be confirmed against the manufacturer datasheet for the exact ordering code. The architecture is suited to conventional single-supply operation because the device can operate close to the positive rail while its output approaches the negative rail. Input common-mode range, output swing, slew rate, and stability conditions still determine whether a particular gain, load, and bypass-capacitor arrangement will meet the design objective. Decoupling should be placed close to the supply pins, and feedback components should be kept compact to minimize parasitic coupling and instability risk. Typical uses include low-level audio stages, current-to-voltage conversion for sensor outputs, general comparator configurations, small-signal amplification, and feedback control around slower feedback loops. The two independent channels can also be configured as comparators, buffers, amplifiers, or differential amplifier sections where their internal characteristics permit the intended operation. Applications requiring very low offset, low noise, high speed, low power, or rail-to-rail output should not assume that a general-purpose LM2904 is the optimal choice. For a robust design, begin with the manufacturer pin configuration and confirm the absolute-maximum ratings, common-mode limits, output-current capability, and recommended external-component values. Avoid using component-marking variants as substitutes without checking the exact pinout, supply range, temperature grade, and package. The TSSOP footprint also requires careful lead pitch and solder-joint inspection because its closely spaced leads are more difficult to inspect than wide-lead SOIC packages. This product page combines the LM2904ATH-13 ordering information, a pin-compatible replacement framework, and practical analog-layout guidance. It highlights the critical decisions engineers must make when reusing an existing 8-pin TSSOP footprint while preserving supply-voltage, common-mode, output-swing, temperature, and load-current requirements.

LM2904AVQDRG4

LM2904AVQDRG4 - Dual 36V 1MHz Op Amp | Texas Instruments

Texas Instruments LM2904AVQDRG4 is a dual, general-purpose operational amplifier with two independent channels, a 1 MHz gain-bandwidth product, and operation from a single supply up to 26 V or split supplies up to 36 V total. The device is packaged in an 8-SOIC package and is supplied on tape and reel. An operational amplifier, or op amp, is a high-gain analog signal-conditioning component that compares its inverting and non-inverting inputs and drives its output toward the difference between them. The LM2904 belongs to the broader hierarchy of dual operational amplifiers, analog amplifiers, integrated circuits, and general-purpose analog signal-processing devices. Its two channels share power pins but otherwise operate independently, allowing one package to provide amplification, buffering, filtering, or comparison functions. The principal benefits are a 1 MHz gain-bandwidth product, a 0.3 V/µs slew rate, and low supply-current drain of approximately 0.7 mA per amplifier. Each amplifier includes frequency compensation and is designed for operation from single or split supplies. The input common-mode range includes ground, which supports common single-supply signal-conditioning arrangements. The automotive-qualified ordering option is identified by the Q designation in the part number, although qualification documentation should be checked for the specific production configuration. The internal architecture is designed for dependable general-purpose operation with a useful combination of gain, bandwidth, input range, and supply flexibility. A typical noninverting amplifier gain of 100 has a closed-loop bandwidth of approximately 10 kHz, while a unity-gain configuration supports signal bandwidth up to the device's stated 1 MHz gain-bandwidth product. These figures make the amplifier suitable for slow sensor signals, audio-frequency circuits, feedback-control loops, and general analog conditioning rather than high-speed data acquisition. Typical applications include industrial sensor interfaces, automotive signal-conditioning modules, low-frequency active filters, audio preamplifier stages, current sensing with resistive shunts, and dual-rail buffer circuits. Two independent channels can process complementary signals or perform separate functions, reducing component count and conserving board area compared with two single amplifiers. When designing the circuit, check input and output common-mode limits at the actual supply voltage. Load output signals through appropriate biasing, use a stable reference for precision offset-sensitive measurements, and avoid operating the amplifier near supply-rail limits without confirming the input and output ranges. Place decoupling capacitors close to the power pins and keep feedback traces short to reduce oscillation and noise pickup. This page consolidates the device identity, ordering information, package details, pin assignment, engineering alternatives, and practical design guidance needed to evaluate the LM2904AVQDRG4 for a new analog circuit.

LM2904AVQPWR

LM2904AVQPWR - Dual 30V 700kHz Op Amp | Texas Instruments

The Texas Instruments LM2904AVQPWR is a dual, general-purpose operational amplifier in an 8-pin TSSOP package, with two independent, internally frequency-compensated amplifiers. The device supports a 30 V maximum total supply rating, delivers a typical gain-bandwidth product of 700 kHz, and operates across a -40°C to 125°C temperature range. Its two-amplifier configuration makes it suitable for signal conditioning, transducer amplification, and analog control circuits using single or split supplies. An operational amplifier is an analog building block that amplifies the voltage difference between its differential input while using negative feedback to set closed-loop gain and bandwidth. The LM2904 belongs to the broader hierarchy of linear amplifiers, analog signal-chain ICs, and semiconductor components. It is internally compensated, which simplifies implementation by removing the need for an external compensation capacitor in standard closed-loop configurations. Key characteristics include low supply-current drain, low input bias and offset currents, and an input common-mode range that extends close to ground for single-supply applications. The typical supply-current consumption is 0.7 mA per amplifier. Its broad supply range and temperature rating support industrial control, automotive, instrumentation, and test-equipment designs where the amplifier must operate across changing supply and ambient conditions. The LM2904 architecture uses two independent, high-gain, frequency-compensated amplifiers in one package. Internal compensation establishes the dominant pole and makes unity-gain operation practical without external compensation components. The 700 kHz gain-bandwidth product supports moderate-frequency signal conditioning rather than high-speed data acquisition, so layout should minimize feedback-loop area and keep sensitive input nodes away from supply and output routing. Typical uses include sensor-amplifier front ends, low-frequency active filters, comparator-style threshold circuits with saturation recovery, audio preamplifier stages, and programmable control interfaces. For automotive and industrial systems, the wide operating-temperature range and wide supply tolerance are especially useful, while the low input bias current helps preserve sensor accuracy. When designing around the LM2904AVQPWR, verify the input common-mode range against the actual signal and supply levels, particularly near the positive rail. Decoupling capacitors should be placed directly across the supply pins, and unused amplifier inputs must be biased rather than left floating. Avoid relying on the device for millivolt-level precision tasks without checking offset, drift, and bias-current contributions for the complete signal chain. This page consolidates package details, verified distributor pricing evidence, drop-in alternatives, and application-oriented design guidance for engineers evaluating the LM2904AVQPWR. It also distinguishes supply-voltage, temperature, channel-count, and bandwidth trade-offs among pin-compatible LM2904-family options.

The operating temperature range extends from -40°C to +125°C, supporting industrial and automotive environments where temperature and qualification requirements exceed those of ordinary general-purpose amplifiers. The internally compensated architecture simplifies implementation of standard inverting, non-inverting, summing, and feedback amplifier circuits. A typical supply current is 500 µA per channel, while output current capability reaches 40 mA per channel. These characteristics make the device suitable for low-power analog signal conditioning where a 3 V minimum supply is required and the circuit must tolerate supply voltages up to 26 V. Typical uses include sensor interfaces, actuator drivers, motor-control feedback networks, battery-powered instrumentation, industrial control loops, and automotive signal-conditioning modules. The wide supply range allows operation from single or split supplies, although the differential voltage between the supply rails must remain within the device limits. Designers should verify output swing, input common-mode range, stability, and load capability across the complete supply and temperature range. Decoupling capacitors should be placed close to the supply pins, while feedback components and sensitive input routes should be kept away from switching nodes to reduce coupling and maintain low offset performance.

LM2904BIDR

LM2904BIDR - Dual 36V 1.2MHz Op Amp | SOIC-10 | TI

The Texas Instruments LM2904BIDR is an industry-standard dual operational amplifier in an 8-pin SOIC package, delivering 1.2 MHz unity-gain bandwidth and a wide 3 V to 36 V supply range with single-supply operation. It is the next-generation 'B' revision of the legacy LM2904, providing tighter DC accuracy (lower input offset voltage), lower noise, and a 1.2 MHz bandwidth upgrade versus the original 700 kHz device, while remaining in the industry-standard 8-pin SOIC footprint used by all LM358 / LM2904 variants. Each channel is a bipolar voltage-frontier amplifier with internal EMI/RFI filtering and ESD protection on the inputs, and the device operates over the automotive -40C to +125C temperature range. An operational amplifier (op amp) is a high-gain DC-coupled differential amplifier whose output voltage is amplified by an external feedback network to perform amplification, filtering, and signal conditioning. A dual op amp integrates two ICs into a single package and is the same circuit-level topology (LDO) integrated with a higher-level power-supply chain and ultimately a semiconductor device, while dual op amps specifically serve as a low-side companion building block used in many sensor, instrumentation, and power-management signal chains. Key features include 1.2 MHz gain-bandwidth product, 0.5 mV typical (3 mV maximum) input offset voltage, 45 V/us (typical) slew rate, 25 nA input bias current, and an output swing that includes both rails. The device operates on a single supply from 3 V up to 36 V (or dual +/-1.5 V to +/-18 V). It is internally compensated for unity-gain stability and includes short-circuit protection on the output, making it suitable for direct drive of low-impedance loads in industrial and automotive environments. The LM2904BIDR uses a bipolar process with a PNP input stage that supports input common-mode voltages down to ground (and up to VCC - 1.5 V), enabling true single-supply operation from a 5 V or 12 V rail. The dual-channel architecture allows one IC to implement two independent gain stages - commonly a transimpedance amplifier and a buffer, or two channels of a differential sensor front-end - saving PCB area, cost, and complexity versus using two single-channel op amps. Typical applications include transducer interfaces (load cells, strain gauges, pressure and flow sensors), low-side current sensing in motor drives and battery management, active filters and integrators for instrumentation, comparator-like threshold detection, and general-purpose signal conditioning on 12 V / 24 V industrial and automotive buses. The wide supply range and automotive-grade temperature rating make it drop-in compatible with virtually every legacy LM288 / LM358 / LM2904 design. When designing with this device, ensure the input common-mode voltage remains within the linear range (GND to VCC - 1.5 V). For single-supply designs, AC-couple the input or bias the network to mid-supply. Decouple the supply pin with a 1 uF / 100 nF parallel pair within 10 mm of the IC, and avoid driving capacitive loads greater than 1 nF directly - add a series isolation resistor if needed.

The device is supplied in an 8-pin SOIC package and provides two amplifier channels in one package. Its 0.7 mA typical supply-current draw supports low-power signal-processing systems. An operational amplifier is an analog amplifier that uses high open-loop gain and negative feedback to amplify voltage differences. Within the semiconductor hierarchy, an operational amplifier belongs to the amplifier IC and signal-conditioning category. The LM2904 combines two general-purpose amplifier channels in a single package, reducing board area when a design requires matched dual-channel functions such as filtering, buffering, or gain stages. The LM2904DE4 provides a 700 kHz gain-bandwidth product, a 0.3 V/µs slew rate, and a low 0.7 mA typical supply-current drain independent of supply voltage. Its common-mode input range includes ground, making it useful in circuits that operate near the lower supply rail. The dual configuration supports applications in industrial controls, sensor interfaces, audio paths, and general-purpose analog signal conditioning. The 26 V maximum supply rating provides ample headroom for conventional industrial supply rails, although the actual operating voltage must remain within the manufacturer’s specified limits. Because this is a general-purpose amplifier rather than a precision part, design engineers should verify input offset, input bias current, output swing, and channel behavior against the application’s signal-integrity requirements. Feedback-network components and signal-source impedances determine practical accuracy and stability. Typical uses include two-stage sensor amplification, low-frequency active filters, buffered instrument inputs, audio preamplification, and general industrial signal conditioning. The 8-pin SOIC package is also compatible with conventional surface-mount assembly and automated PCB manufacturing. The dual organization allows one package to implement complementary signal paths while reducing component count compared with two separate single amplifiers. For stable operation, follow the manufacturer’s recommended compensation and decoupling practices, place input and output networks close to the device, and avoid driving the output beyond its specified load and swing limits. Grounding and trace-return paths should be planned to prevent supply and ground noise from entering the signal path. The manufacturer datasheet is the controlling reference for electrical limits, pin functions, and application details. This product page combines the official family specifications with practical design guidance, application fit analysis, and a package-focused replacement comparison. It is intended to help engineers identify the correct operating limits and select a pin-compatible alternative without overlooking differences in bandwidth, slew rate, supply current, or package construction.

onsemi LM2904DG is a dual, general-purpose operational amplifier with two independent amplifiers, 1 MHz gain-bandwidth product, 0.6 V/us slew rate, and a 3 V to 32 V supply range in an 8-pin SOIC package. It supports single-supply or split-supply operation and accepts input common-mode voltages extending to ground and VEE. An operational amplifier is a voltage-controlled differential amplifier used to amplify, buffer, filter, compare, or drive analog signals. The LM2904 belongs to the broader operational-amplifier hierarchy, where the dual configuration provides two signal-processing channels in one package. This makes it useful where board area, component count, and supply flexibility are more important than precision or high speed. Key features include a 1 MHz gain-bandwidth product, 0.6 V/us slew rate, and a minimum common-mode rejection ratio of 50 dB. The device is specified for a 3 V to 32 V total supply, allowing operation from a single positive rail or from positive and negative rails. Its common-mode input range extends to ground and VEE, which supports battery-powered, industrial-control, and sensor-interface designs where input signals may approach the lower supply rail. The input offset voltage is listed at 7 mV, making this amplifier more appropriate for general-purpose amplification than precision instrumentation applications requiring microvolt-level offset. Its moderate gain-bandwidth product and slew rate are appropriate for audio-frequency control loops, slow sensor signals, active filtering, comparators, and general analog signal conditioning. The dual architecture also allows both amplifiers to share the same supply and decoupling network. Typical uses include DC motor and actuator feedback control, transducer buffering, low-frequency active filters, audio preamplification, regulated power-supply feedback, and general-purpose analog interfaces. Split-supply operation can simplify biasing around ground, while single-supply operation helps reduce system power and board complexity in battery-operated equipment. Designers should account for input bias current, output-current capability, common-mode limits, and stability when driving capacitive loads. Place decoupling capacitors close to the supply pins, keep feedback routing compact, and verify output swing against the actual load. For applications requiring very low offset, very wide bandwidth, rail-to-rail output, or automotive qualification, compare the LM2904 family against more specialized amplifier families. This product page combines manufacturer-datasheet characteristics, verified distributor listings, drop-in replacement analysis, application guidance, and package-level design notes to support faster component evaluation and PCB reuse decisions.
