LM258AD

LM258AD - Dual 30V 700kHz Op Amp | Texas Instruments

The Texas Instruments LM258AD is a dual, internally frequency-compensated operational amplifier designed for low-power operation from a single supply. It combines a 30 V maximum supply rating, 700 kHz gain-bandwidth product, 1.1 MHz unity-gain bandwidth, and approximately 500 uA supply current per amplifier in an 8-pin SOIC package. The device provides two independent amplifiers in one package and operates over the -25°C to 85°C temperature range. An operational amplifier is an analog signal-conditioning IC that uses high open-loop gain to amplify the difference between voltages applied to its inverting and non-inverting inputs. The LM258AD belongs to the operational-amplifier family within the broader linear-amplifier and analog-signal-processing hierarchy. Its internally frequency-compensated architecture eliminates the need for an external compensation capacitor in typical closed-loop configurations. Key features include a large DC voltage gain of 100 dB, a 1.1 MHz unity-gain bandwidth, low input bias current of 20 nA, and supply current that remains essentially independent of supply-voltage magnitude. The two amplifiers can be used in non-inverting, inverting, comparator, summing, difference, and general feedback configurations. The single-supply capability also supports battery-powered and industrial signal-conditioning equipment. Each amplifier is intended for operation over a wide supply range, with the verified manufacturer description identifying a 30 V maximum supply voltage and a -25°C to 85°C operating-temperature range. Internal frequency compensation makes the device suitable for straightforward fixed-gain implementations without an additional compensation network. Engineers should still account for input common-mode limits, output swing, stability, input offset, and output-current limitations according to the manufacturer datasheet. Typical applications include transducer and sensor-signal conditioning, low-current industrial control, audio preamplification, bridge-amplifier interfaces, and power-supply feedback networks. The dual configuration saves board area when two low-frequency analog channels are required. Compared with a switching regulator or a modern rail-to-rail amplifier, the LM258AD prioritizes low quiescent current, wide supply-voltage headroom, and straightforward single-supply operation. When laying out the circuit, keep input and feedback paths short and place compensation or filtering capacitors close to their associated pins when required by the selected topology. Check output-current demand and input common-mode range against the actual supply voltage. Do not assume rail-to-rail input or output behavior; the available headroom and output swing are important constraints in low-voltage designs. This page consolidates the verified manufacturer specifications, distributor availability information, package details, and practical selection guidance. It also distinguishes pin-compatible alternatives from merely similar amplifiers and highlights missing electrical data explicitly rather than estimating values that are not established by the supplied sources.

LM258AH

LM258AH - Dual 30V Low-Power Op Amp | STMicroelectronics

STMicroelectronics LM258AH is a dual, low-power operational amplifier designed for single-supply operation over a wide voltage range, with two independent, internally frequency-compensated amplifiers in an 8-lead TO-99-8 metal package. The LM258 family supports input voltages up to 30 V, operating frequency up to 700 kHz, and an industrial ambient-temperature range of -25 °C to +85 °C. The LM258AH ordering suffix identifies the wire-lead TO-99-8 industrial-temperature configuration. An operational amplifier, or op amp, is a high-gain analog building block used to amplify small voltage signals. Within the wider semiconductor hierarchy, the LM258AH is an analog integrated circuit and a dual operational amplifier. Its two independent channels can support signal conditioning, feedback control, voltage comparison, and general-purpose analog amplification without requiring a split-supply arrangement. The key features of the LM258AH include two amplifiers in one package, internal frequency compensation, and a maximum input voltage of 30 V. The LM258 family is designed around a 700 kHz gain-bandwidth characteristic, while the LM258A version has an input offset voltage specified as 3 mV by the cited manufacturer information. The low-power architecture is intended for applications that require wider supply-voltage tolerance than conventional low-voltage single-supply op amps. The internally compensated architecture simplifies closed-loop amplifier design because it avoids the external compensation components normally required by higher-gain parts. Independent channels may also be used for unrelated signal paths, although common supply pins mean both channels share the same operating rail and thermal environment. Designers should still verify output swing, input common-mode range, output-current capability, and stability against their actual source and load impedances. Typical uses include industrial process-control loops, sensor-signal conditioning, low-frequency filter stages, comparators, and general analog signal chains. The wide operating-voltage capability can simplify legacy and industrial designs that operate from higher single rails. The 700 kHz bandwidth is appropriate for low-frequency precision and control tasks, but it is generally not the preferred choice for high-speed video, RF, or wideband data-acquisition requirements. The principal design considerations are supply decoupling, input common-mode limits, output swing, and thermal behavior. Place the supply bypass capacitor close to the device and avoid driving outputs into hard clamps except where the application intentionally requires saturation. Verify the complete circuit against the STMicroelectronics LM258 datasheet, particularly for AC output current, noise, offset voltage, and load-capacitance stability. This product page consolidates the verified manufacturer and distributor information for the LM258AH and distinguishes the TO-99-8 metal-package option from surface-mount and other package variants. It also provides compatibility-focused replacement guidance, practical circuit considerations, and a specification comparison structured around engineers evaluating an existing TO-99-8 dual-op-amp design.

The device supports input voltages up to 30 V, operates across the -25°C to +85°C temperature range, and features a 700 kHz gain-bandwidth product. Its dual-channel configuration allows one package to implement two amplification, filtering, comparison, or signal-conditioning functions. An operational amplifier is a high-gain analog signal-processing IC that compares its inverting and non-inverting inputs and drives its output according to the voltage difference between them. The LM258 family belongs to the operational-amplifier category within analog amplifiers and linear integrated circuits. It is intended for general-purpose designs rather than precision, low-noise, or high-speed instrumentation, providing a practical balance of supply range, gain, common-mode capability, and output swing. Key features include two independent channels, large DC voltage gain of 100 dB, and internal frequency compensation that supports unity-gain operation without an external compensation network. The input common-mode voltage range includes ground, supporting single-supply signal conditioning where the signal is referenced to 0 V. These characteristics make the LM258AM suitable for transducers, industrial controls, audio and communication interfaces, sensor amplification, and general feedback-control circuits. The architecture is based on two independent high-gain amplifier sections with internal compensation. Internal compensation simplifies PCB design and improves usability at unity gain, while the wide supply range permits operation from lower-voltage single supplies through industrial supplies up to 30 V. Because this is a general-purpose bipolar-style amplifier family, engineers should verify input common-mode limits, output swing, load capability, stability, and supply-current requirements against the manufacturer datasheet for the exact operating conditions. Typical applications include current-loop and voltage-feedback control, low-side sensing, sensor signal conditioning, audio preamplification, active filtering, threshold detection, and general industrial interface circuits. The dual arrangement is especially useful when a design needs two related functions, such as an error amplifier paired with a buffer or a comparator paired with a gain stage. When laying out an LM258AM circuit, keep input and feedback connections compact to minimize parasitic pickup, provide adequate supply bypassing near the device, and verify that source and load impedances remain within the stability requirements of the internal compensation. The SOIC-8 package also allows a smaller footprint than a traditional through-hole dual operational amplifier. This page consolidates the LM258AM electrical characteristics, package information, verified source links, replacement considerations, comparison parameters, and practical design guidance into one engineering-focused resource for part selection and PCB implementation.

LM258AN

LM258AN - Dual Low-Power Op Amp | STMicroelectronics

STMicroelectronics LM258AN is a low-power dual operational amplifier containing two independent, high-gain, internally frequency-compensated amplifiers. It is packaged in an 8-pin Mini DIP and is designed for single-supply operation over a wide voltage range. Each channel is internally compensated for unity-gain stability, allowing operation without an external frequency-compensation network. An operational amplifier, or op amp, is a voltage-gain amplifier that compares an inverting input with a non-inverting input and drives its output toward the difference between them. The LM258 belongs to the broader linear-IC hierarchy: operational amplifier, analog amplifier, voltage amplifier, and semiconductor. Internally compensated dual op amps are useful when a board needs two independent amplifier channels while limiting component count and keeping the two channels in one package. The LM258AN provides two amplifier circuits with a large DC voltage gain of 100 dB and unity-gain frequency compensation. Its input common-mode voltage range includes ground, an important characteristic for circuits powered from a single positive supply and biased near the lower supply rail. The low-power architecture is designed to maintain low supply drain independently of the magnitude of the supply voltage, according to the manufacturer family documentation. Each amplifier channel has separate input and output pins, while the two channels share the power supply connections. This arrangement supports conventional non-inverting, inverting, voltage follower, summing, and differential signal-conditioning circuits. Because the amplifiers are internally compensated, stable unity-gain operation can be implemented with a minimum external feedback network, reducing design effort in general-purpose analog equipment. Typical LM258AN applications include sensor-signal conditioning, industrial control loops, low-frequency active filters, relay-driver interfaces, audio preamplifier stages, and buffered measurement systems. The dual configuration is especially useful when a circuit requires two related analog channels, such as an instrumentation amplifier input stage, motor-control feedback network, or dual-channel sensor interface. When designing around the LM258AN, verify the exact input common-mode range, output swing, supply-current limits, and operating-temperature limits for the LM258 variant against the STMicroelectronics datasheet. Decoupling capacitors should be placed close to the supply pins, and the feedback network should preserve stable operation at the intended signal frequency. This product page combines the LM258AN family characteristics, package information, sourcing guidance, comparison parameters, and practical circuit-planning notes. It is intended to help engineers evaluate the device for single-supply analog designs and identify same-package alternatives without overlooking package or qualification differences.

LM258AP

LM258AP - Dual 30V 700kHz Op Amp | Texas Instruments

Texas Instruments LM258AP is a dual, general-purpose operational amplifier supplied in an 8-pin PDIP package. It supports operation from a single supply or split supply over a wide voltage range, with a maximum total supply voltage of 32 V. The LM258 family provides 700 kHz gain-bandwidth product, 0.3 V/µs slew rate, and approximately 3 mV input offset voltage for the LM258A version, making it suitable for conventional analog signal conditioning. An operational amplifier is an analog semiconductor that amplifies the voltage difference between its two inputs. Its applications include voltage buffers, current-to-voltage conversion, active filters, comparators, instrumentation circuits, and low-frequency closed-loop control. The dual LM258 architecture provides two amplifiers in one package, reducing board area in designs that need independent or complementary analog channels. The LM258A operating-temperature range extends from -25°C to 85°C. The principal characteristics are a 700 kHz typical gain-bandwidth product, 0.3 V/µs slew rate, and 3 mV offset voltage for LM258A. The device operates with total supply voltages from 3 V to 32 V, including single-supply configurations near 3 V and split supplies up to approximately ±16 V. Its 8-pin PDIP package also facilitates prototyping and through-hole assembly where leaded components are preferred. LM258 devices are internally frequency-compensated dual operational amplifiers. Internal compensation allows operation as unity-gain voltage followers without external compensation components, which simplifies many basic amplifier layouts. Users must still observe input common-mode and output-swing limits, maintain the specified supply voltage, and use adequate bypassing to prevent oscillation or unexpected analog noise. The dual configuration also permits one channel to perform signal amplification while the other handles a separate task. Typical uses include low-frequency active filters, DC sensor amplification, industrial control-signal conditioning, audio preamplifier stages, comparators, and general instrumentation. In a basic non-inverting stage, the closed-loop gain is established by the feedback network, while the amplifier provides high input impedance and low output impedance. In a transimpedance stage, the feedback resistor converts input current into a voltage, making the LM258 suitable for photodiode and detector interfaces when operating within its bandwidth and dynamic-range limits. A critical design consideration is to place the specified bypass capacitor close to the supply pins and route feedback components to minimize parasitic capacitance and oscillation risk. Check common-mode input range, output swing, load capability, and thermal dissipation at the actual supply voltage. Keep sensitive input nodes away from switching-current paths and use a stable ground reference to reduce offset and noise pickup. This product page combines manufacturer specifications, package details, drop-in alternatives, application guidance, and design considerations for engineers evaluating the LM258AP. It also distinguishes verified electrical parameters from parameters that require design confirmation, helping teams plan analog prototypes, production PCB layouts, and replacement decisions with fewer assumption-driven errors.

LM258D

LM258D - Dual 30V Operational Amplifier | STMicroelectronics

The STMicroelectronics LM258D is a dual, internally frequency-compensated operational-amplifier IC with two independent amplifiers, a 30 V maximum supply rating and a 700 kHz gain-bandwidth product. Each amplifier is designed for general-purpose signal conditioning from single or split supplies. The device is packaged for surface mounting in an 8-pin SOIC and is identified by the DigiKey listing as a standard, general-purpose, two-circuit amplifier. The supplied source data confirms the 30 V and 700 kHz headline ratings through Texas Instruments’ LM258 family page, but it does not provide a complete STMicroelectronics parameter table. An operational amplifier is a voltage-gain element that uses external feedback to control closed-loop behavior. The LM258D belongs to the dual operational-amplifier hierarchy and contains two independent amplifiers in one package. Internal frequency compensation makes each amplifier stable without an external compensation network in many voltage-follower and conventional feedback configurations. Its common-mode range extending toward ground, together with single-supply operation, makes this device class useful in battery-powered, industrial-control and instrumentation circuits where the signal can approach the lower supply rail. The principal design benefit is integration: two amplifiers occupy one 8-SOIC package rather than requiring two separate single amplifiers. Both channels can amplify a pair of related signals, form two halves of an active filter, or implement independent comparators and buffers. The 700 kHz gain-bandwidth product supports moderate-frequency signal paths, while the 30 V supply class accommodates higher-voltage industrial rails. Designers must still check input range, output swing, slew rate, offset, bias current and load capability against the exact manufacturer datasheet before releasing production hardware. Technically, internal frequency compensation trades bandwidth and other performance characteristics for ease of use. Stable operation does not make every feedback topology valid, and real circuits still require attention to output loading, input common-mode range, supply decoupling and stability around capacitive loads. Two amplifiers do not share their supply pins internally at the component level, so both sections use the package’s common positive and ground connections. PCB grounding and bypass placement determine whether the theoretical noise and transient performance can be realized. Typical applications include transducer-signal conditioning, low-side current measurement, loop-error amplification, active filtering, audio preamplification, motor-control interfaces and general dual-rail amplification. A single-supply sensor circuit can use one amplifier for conditioning and the other for an offset, filter or intermediate buffer stage. Split-supply instrumentation can use both channels more independently. Compared with modern low-voltage rail-to-rail amplifiers, the LM258D trades compactness and precision for its wide-supply capability and straightforward general-purpose use. When designing around the LM258D, place the supply bypass capacitor close to the IC and route each amplifier’s inputs and outputs to minimize leakage and feedback-loop pickup. Confirm that signals stay within the common-mode and output-swing limits under the worst supply, temperature and load conditions. Do not treat a distributor cross-reference result as proof of equivalence; verify pin mapping, electrical limits, stability and temperature grade in the selected replacement manufacturer’s datasheet. This page combines the verified distributor identification, official family-page information, cross-reference evidence and package-level design guidance. It distinguishes confirmed facts from parameters that were not supplied, avoiding invented precision while helping engineers evaluate LM258D procurement, replacement and circuit-integration decisions.

The device is supplied in an 8-pin SOIC package. Its low-power design, common-mode input range extending toward ground or VEE, and support for single-supply or split-supply operation make it suitable for industrial control, instrumentation, sensor conditioning, and low-frequency signal-processing systems. An operational amplifier, or op amp, is a voltage-gain building block within analog and mixed-signal electronics. A dual op amp contains two amplifiers in one package, allowing one device to implement two independent signal paths or a differential stage. The LM258DG belongs to the operational-amplifier hierarchy: dual operational amplifier, general-purpose amplifier, analog IC, and ultimately semiconductor. Its broad supply range accommodates conventional industrial rails, while its ground-referenced input capability simplifies designs powered from a single supply. Key verified characteristics include two amplifier circuits, 1 MHz gain-bandwidth product, 0.6 V/µs slew rate, and operation from 3 V to 32 V. The listed operating temperature range is -25 °C to 85 °C. Because the gain-bandwidth product is 1 MHz, the device is best suited to low-frequency amplification, buffering, comparators, and general feedback-control loops rather than high-speed signal processing. The LM258 architecture derives from the circuit designs used in quad operational amplifiers. This dual configuration provides functional flexibility while limiting package count and board area. Single-supply operation allows the input and output signals to remain near the lower supply rail, and split-supply operation permits bipolar-style signal paths. The verified operating range supports both 3 V minimum-supply designs and higher-voltage industrial systems. Typical applications include sensor signal conditioning, transducer amplification, current-loop interfaces, low-frequency active filters, and general-purpose analog buffers. Its two channels can also be used together as a differential amplifier when the circuit requires matched amplifier functions in one package. Applications should account for the 1 MHz bandwidth and 0.6 V/µs slew rate when setting gain, bandwidth, and expected output slew behavior. A key design consideration is verifying input and output voltage excursions for the selected single- or split-supply configuration. Decoupling and stability should be implemented around the circuit required by the ON Semiconductor LM258 datasheet and the particular feedback network. Because detailed pin names, offset voltage, input bias current, and noise figures were not supplied in the verified data, those values must be confirmed before production release. This page consolidates verified distributor specifications, sourcing information, same-package replacement candidates, and practical selection guidance. It adds engineering context for supply-range, bandwidth, packaging, and replacement decisions while clearly separating verified facts from unavailable parameters.

LM258DT

LM258DT - Dual 30V Low-Power Op Amp | STMicroelectronics

The STMicroelectronics LM258DT is a low-power, dual, internally frequency-compensated operational amplifier with two independent amplifiers, a 3 V to 30 V single-supply operating range, and an 8-pin SOIC package. Its unity-gain bandwidth is 1.1 MHz, while its slew rate is 0.6 V/us. The device is designed for single-supply operation over a wide voltage range and provides large DC voltage gain of 100 dB. An operational amplifier is an analog signal-conditioning IC that uses high open-loop gain and negative feedback to amplify, buffer, filter, or compare voltages. The LM258DT belongs to the bipolar operational-amplifier family and combines two amplifiers in one package, reducing board area when a circuit needs matched general-purpose gain stages. Its internally frequency-compensated architecture simplifies closed-loop design because the compensation network is integrated rather than added externally. Each amplifier offers a unity-gain bandwidth of 1.1 MHz and a slew rate of 0.6 V/us, making the device suitable for audio-frequency signal paths, sensor conditioning, active filtering, voltage amplification, and general feedback-control blocks. The low-power supply drain is approximately 500 uA per amplifier and is essentially independent of supply-voltage magnitude. The low input bias current of approximately 20 nA also helps minimize source-loading errors in high-impedance sensing circuits. The dual architecture supports independent signal paths, including two noninverting stages, two inverting stages, mixed gain stages, or a buffer paired with an active filter. Both amplifiers share the same supply pins but operate independently. Their common supply range allows them to use a single rail in portable instrumentation, industrial control, sensor interfaces, and low-voltage embedded systems. The 8-SOIC package is suitable for conventional surface-mount PCB assembly and temperature-controlled lead-free manufacturing processes. Designers should account for input and output voltage limitations when using a single positive supply. The LM258DT is not a rail-to-rail input or output device, so the usable signal range must remain inside the common-mode and output-swing limits stated in the manufacturer datasheet. Place bypassing capacitors close to the supply pins and maintain adequate PCB copper for heat dissipation. Stable operation also depends on selecting appropriate feedback components and avoiding capacitive loading directly at the amplifier output. This product page combines the LM258DT electrical characteristics, package and pin information, application guidance, comparison criteria, and practical design considerations into a compact engineering reference for initial design decisions.

LM258H

LM258H - Dual 30V 700kHz Op Amp | Texas Instruments

The Texas Instruments LM258H is a dual general-purpose operational amplifier with a 30 V supply rating, 700 kHz gain-bandwidth product, and operation from -25°C to 85°C. The LM258H is supplied in the metal-can TO-99-8 package and provides two amplifiers per package. Its precision-oriented counterpart grades, including the LM358 family, use the same dual-amplifier architecture for common industrial signal-conditioning designs. An operational amplifier is an active semiconductor device that uses high-gain differential amplification to increase the voltage difference between its differential input and drive its output. Operational amplifiers belong to the amplifier IC hierarchy and are commonly used in sensor interfaces, buffer stages, integrators, comparators, and control loops. The LM258 family is positioned as a general-purpose bipolar amplifier rather than a high-speed, low-noise, or precision-specific device. The manufacturer identifies the LM258 family as dual, 30 V, 700 kHz operational amplifiers. The LM258H ordering variant is associated with the TO-99-8 metal-can package, while the broader LM258 family also includes other package and temperature options. The verified distributor listing describes LM258H as a two-circuit amplifier in a TO-99-8 package. The H suffix is used in the manufacturer ordering information, but individual suffix-specific electrical values must be confirmed against the ordering table in the manufacturer datasheet. The 700 kHz gain-bandwidth product is the principal verified speed parameter. It describes the approximate closed-loop bandwidth available for unity-gain operation under the stated test conditions, subject to the manufacturer datasheet's load and test assumptions. The 30 V rating identifies the device as suitable for higher-voltage analog signal chains than basic low-voltage single-supply amplifiers, provided the selected grade and supply arrangement meet the complete datasheet limits. Operating temperature is specified from -25°C to 85°C for the LM258 family. Typical uses include buffered sensor signals, low-frequency active filters, analog summing and difference amplifiers, current-loop buffering, audio and communications signal conditioning, and general industrial control interfaces. Because the verified data does not provide output-current, input-offset, noise, slew-rate, load-current, common-mode, or package-dimension values, those parameters should not be inferred for design calculations. Engineers should use the manufacturer datasheet for the exact LM258H grade limits and test conditions. The main design consideration is ensuring that the selected dual amplifier's pinout, supply voltages, input common-mode range, output swing, and load conditions match the completed analog design. TO-99-8 is a through-hole metal-can package, so PCB footprint selection and mechanical clearance require the package drawing rather than a modern SMD assumption. Decoupling, grounding, and stable feedback compensation remain necessary even when using a general-purpose amplifier. This page combines the verified manufacturer product identity, distributor package information, ordering context, and design-oriented interpretation. It also distinguishes verified LM258 family facts from parameters that still require confirmation from the manufacturer datasheet, helping engineers move from part selection to a qualified schematic without inserting unsupported assumptions.

The LM258N is a dual, general-purpose operational amplifier designed for single-supply operation over a 3 V to 30 V range, with a stated 32 V maximum supply rating in the verified product data. It provides two independent amplifiers in an 8-pin Mini DIP package and operates from -25°C to 85°C. Each channel combines a high-gain, internally frequency-compensated architecture with a typical gain-bandwidth product of 1.1 MHz and a typical slew rate of 0.6 V/µs. The device is intended for general-purpose signal conditioning, transducer interfaces, and low-frequency analog control applications. An operational amplifier is a high-gain analog building block that compares two input voltages and drives its output to reduce their difference. A differential input amplifier, voltage follower, comparator-style interface, or control loop can be built around the LM258N when the required bandwidth, slew rate, supply voltage, and input/output range fit the device. The LM358-family architecture also allows operation from a single supply or split supply, making it useful in systems whose signal is referenced near ground. Verified product information identifies the LM258-N as a dual 32 V, 700 kHz operational amplifier with -25°C to 85°C operation. The related LM258N distributor listings identify an 8-pin Mini DIP package and a general-purpose dual amplifier configuration. The device is therefore suited to industrial and instrumentation circuits where a through-hole package and wide supply range are useful, provided the circuit designer checks the exact manufacturer datasheet for input common-mode limits, output swing, supply current, offset voltage, and thermal limits. The internally compensated amplifiers simplify implementation of unity-gain and conventional inverting or non-inverting stages because no external compensation network is required for ordinary closed-loop use. The 1.1 MHz gain-bandwidth product supports many low-frequency signal paths, while the 0.6 V/µs slew rate limits large-signal response. These characteristics make the LM258N more appropriate for instrumentation, buffering, and control than for high-speed signal chains. Typical uses include sensor signal conditioning, low-frequency active filters, audio and communications interface stages, analog control loops, and general dual-amplifier boards. In a single-supply circuit, the input and output signal ranges must remain inside the device's allowable common-mode and output-swing limits. The 8-pin DIP package also favors through-hole prototyping and repairable industrial assemblies. For PCB layout, keep input and feedback paths short, provide a solid ground reference, and place decoupling capacitors close to the supply pins. Avoid placing noisy switching nodes beside high-impedance input traces. Because the verified data does not provide every electrical limit, exact compliance status, pricing, or an official pin mapping for the generic LM258N ordering code, those details remain marked as data needed rather than inferred.

LM258NG

LM258NG - Dual 1MHz Operational Amplifier | onsemi

onsemi LM258NG is a dual, general-purpose operational amplifier with a 1 MHz gain-bandwidth product, 0.6 V/µs slew rate, and operation from 3 V to 32 V in an 8-pin PDIP package. The device provides two amplifier circuits in one through-hole package and supports single-supply or split-supply operation. Its common-mode input voltage range extends toward ground or VEE, making it suitable for industrial, instrumentation, control, and signal-conditioning systems where single-rail operation is advantageous. An operational amplifier is a high-gain differential amplifier used to amplify, buffer, compare, or integrate signals. The LM258NG belongs to the dual general-purpose operational-amplifier class and within the broader hierarchy of analog ICs, analog signal-chain components, and semiconductor devices. Unlike rail-to-rail precision amplifiers, its practical input and output ranges depend on its supply voltage and circuit configuration. Designers should therefore evaluate common-mode range, output swing, input bias current, and load capability against their signal levels. The principal verified characteristics are a 1 MHz gain-bandwidth product, 0.6 V/µs slew rate, dual-circuit construction, and a 3 V to 32 V operating supply range. The low-power-drain architecture is useful in battery-powered or space-constrained equipment, while the common-mode range extending to ground or VEE improves usefulness in systems powered from one positive rail. The 8-pin PDIP package also supports conventional through-hole assembly and socket-level serviceability. The LM258NG architecture is suited to general-purpose feedback stages rather than high-speed signal chains. A 1 MHz gain-bandwidth product provides usable bandwidth at modest closed-loop gains, while the 0.6 V/µs slew rate limits how quickly output voltage can follow a changing input. In gain configurations with substantial noise gain, the available closed-loop bandwidth is lower. Stable feedback-network design and appropriate output loading are therefore necessary to avoid oscillation or slew-limited operation. Typical uses include low-frequency sensor signal conditioning, industrial control-loop amplifiers, audio preamplification, comparators with external hysteresis, and buffered instrumentation inputs. The dual configuration can implement two independent amplifier sections on one PCB. In a single-supply circuit, input and output grounding must be referenced carefully because the common-mode range reaches ground or VEE but is not necessarily a rail-to-rail input specification. A key design consideration is power-supply decoupling: place a suitable bypass capacitor close to each supply pin and route return currents without splitting analog ground paths. Check output swing and load current at the lowest supply voltage, and use output isolation when driving capacitive loads. These checks are especially important because the available verified data does not specify detailed offset, bias-current, thermal, or output-drive limits. This page consolidates verified distributor specifications, package information, practical application guidance, and verified web-data drop-in candidates. It also distinguishes confirmed facts from parameters that still require confirmation from the manufacturer datasheet, helping engineers identify the LM258NG quickly while avoiding unsupported assumptions.

LM258P

LM258P - Dual 30 V 700 kHz Op Amp | Texas Instruments

The Texas Instruments LM258P is a dual, internally frequency-compensated operational amplifier with a 30 V supply rating, 700 kHz gain-bandwidth product, and operation from -25°C to 85°C, housed in an 8-pin PDIP package. One package contains two independent amplifiers, making it suitable for dual-channel signal conditioning, transducers, control loops, and general-purpose analog systems. An operational amplifier is a voltage-gain building block within analog and mixed-signal electronics. The LM258P belongs to the bipolar operational-amplifier family, combining differential inputs, high voltage gain, internal frequency compensation, and common operation from a single or split supply. Its two independent channels allow simultaneous amplification, filtering, buffering, or feedback control without requiring two separate amplifier packages. The verified source data identifies a wide supply-voltage operating range, high DC voltage gain, unity-gain bandwidth, low supply current, and low input-bias current. The search results specifically identify 100 dB large DC voltage gain, 1.1 MHz unity-gain bandwidth, approximately 500 µA supply current per amplifier, and approximately 20 nA input-bias current. These characteristics make the device relevant to instrumentation where useful closed-loop accuracy is more important than very high speed. Each amplifier is independently compensated, allowing normal operation without external frequency-compensation components. Input and output-device choices support practical single-supply and split-supply arrangements, while the dual configuration can reduce board area in paired channels. Nevertheless, output-current capability, common-mode limits, input-offset behavior, noise, and stability should be checked against the complete manufacturer datasheet before precision or load-heavy use. Typical uses include transducer signal conditioning, low-frequency active filters, sensor amplification, instrumentation amplifiers, sample-and-hold interfaces, and industrial control loops. The 8-pin PDIP package is appropriate for through-hole assembly and prototypes, and its wide temperature coverage supports equipment operating across industrial temperature ranges. PCB design should keep input and feedback paths short, provide adequate supply bypassing, and maintain a stable reference or mid-supply point when the output must remain biased above ground in single-supply operation. Avoid relying on the verified snippets for load-current or saturation limits; those values require the complete LM258 manufacturer datasheet. This page consolidates the verified LM258P identity, package, temperature, supply, bandwidth, gain, current, pricing, and sourcing information with engineering guidance. It also distinguishes verified facts from parameters that still require full-datasheet confirmation, providing a practical basis for initial design and procurement review.

LM258PT

LM258PT - Dual 1.1 MHz Low-Power Op Amp | STMicroelectronics

The STMicroelectronics LM258PT is a dual low-power bipolar operational amplifier packaged in an 8-pin TSSOP. Each of its two independent, internally frequency-compensated amplifiers provides a 100 dB large-signal voltage gain, a 1.1 MHz unity-gain bandwidth, and approximately 500 uA of supply current per amplifier. The device is designed for single-supply operation across a wide voltage range and supports general-purpose signal conditioning. An operational amplifier, or op amp, is a high-gain differential-input amplifier whose inverting and non-inverting inputs produce a single-ended output. Internally frequency-compensated op amps such as the LM258PT are internally stabilized for unity-gain operation without an external compensation network. This makes them suitable for amplifier, buffer, comparator, transducer, and feedback-control circuits where simplicity and low quiescent current are more important than very high bandwidth. Key characteristics include two amplifier circuits in one package, a large DC voltage gain of 100 dB, a 1.1 MHz unity-gain bandwidth, approximately 500 uA of supply current per amplifier, and a typical input bias current of 20 nA. Because the two channels are independent, engineers can use them for cascaded gain stages, differential signal conditioning, active filtering, or separate control and monitoring functions. The internal frequency compensation eliminates the need for external dominant-pole components in most unity-gain applications. The LM258PT is a bipolar-input general-purpose amplifier rather than a rail-to-rail CMOS op amp. Its design is appropriate when a single supply rail is available, input-referred offset is not the dominant system requirement, and operation from a non-rail-to-rail output range is acceptable. Designers must still account for the output-swing limits, common-mode input range, stability requirements, and load capability described by the manufacturer datasheet. Typical uses include low-frequency transducer amplification, sensor signal conditioning, audio preamplification, battery-powered instrumentation, feedback amplifiers in control loops, and general dual-amplifier boards. Its 8-pin TSSOP footprint permits compact surface-mount layouts, while the low 500 uA-per-amplifier supply current helps preserve battery life in portable systems. The main design consideration is stability around the op amp. Place input and output components close to their associated pins, verify capacitive loading against the datasheet stability limits, and avoid driving the output into hard clipping when the input signal exceeds the available output swing. Using the device as a unity-gain buffer requires particular care with capacitive loads because the internal compensation is optimized for a specified load range. This page consolidates manufacturer and distributor information, package details, verified pricing, drop-in alternatives, application guidance, and design notes. It is intended to complement the manufacturer datasheet with selection and implementation context that is not normally presented on a distributor listing page.

LM258QT

LM258QT - Dual 1.1MHz Op Amp | STMicroelectronics

The STMicroelectronics LM258QT is a low-power dual operational amplifier with two independent, internally frequency-compensated amplifiers, a 1.1 MHz unity-gain bandwidth, 100 dB large-signal voltage gain, and an 85 dB common-mode rejection ratio. The device is supplied in an 8-pin DFN package measuring 2 x 2 mm and operates from 3 V to 30 V on a single supply or from ±1.5 V to ±15 V on dual supplies. An operational amplifier is a high-gain analog signal-conditioning IC that compares differential input voltages and amplifies the result. The LM258QT belongs to the operational amplifier hierarchy, where it combines amplifier signal gain, input protection, frequency compensation, and output-current capability in one package. Its two independent channels make it useful for dual-channel signal paths, instrumentation, transducer amplification, and general-purpose analog control. Key features include a 1.1 MHz gain-bandwidth product, 0.6 V/µs slew rate, 2 mV input offset voltage, approximately 20 nA input bias current, and 100 dB DC voltage gain. The low-power architecture is intended for operation across a broad supply-voltage range, while internal frequency compensation avoids the need for external compensation components in standard closed-loop configurations. The two amplifiers are independent, allowing them to amplify different signals or drive separate analog stages. Its 85 dB CMRR helps reject common-mode interference, while its 0.6 V/µs slew rate supports moderate signal slewing requirements. The 1.1 MHz bandwidth is appropriate for low-to-moderate-frequency precision and control circuits rather than high-speed video or RF signal chains. Typical applications include sensor and transducer signal conditioning, industrial control loops, low-frequency measurement instrumentation, audio preamplification, and general-purpose dual-channel amplification. The two-amplifier configuration can reduce component count when a board needs two related analog functions, provided both channels have compatible signal ranges and grounding requirements. Designers should preserve the datasheet-recommended bypass capacitance, verify output swing and load-current limits, and account for input common-mode range near the supply rails. The DFN-8 package also requires careful PCB layout, exposed-pad thermal management, and short feedback and input paths to preserve stability and reduce parasitic effects. This page consolidates verified distributor pricing, package and electrical details, practical application guidance, and pin-compatible replacement information. It also highlights the LM258QT's key engineering trade-offs so purchasing and design decisions can be made against verified source data rather than generic operational-amplifier assumptions.

LM258YPT

LM258YPT - Dual Low-Power Op Amp | STMicroelectronics

The STMicroelectronics LM258YPT is a low-power dual operational amplifier consisting of two independent, high-gain, internally frequency-compensated amplifiers in an 8-pin TSSOP package. According to the manufacturer product page, the device is designed for single-supply operation over a wide voltage range, while the distributor listing identifies a 100 dB gain specification and 1.1 MHz bandwidth. Each amplifier includes low-input-bias-current characteristics suited to feedback, sensing, and signal-conditioning circuits. An operational amplifier is a high-gain analog building block that compares two input voltages and drives its output toward the difference between them. The LM258 belongs to the dual operational-amplifier family within the broader linear IC and amplifier hierarchy. Internally frequency compensation simplifies closed-loop use because designers do not need to add an external dominant-pole capacitor for ordinary stable operation. The LM258YPT provides two amplifiers in one compact surface-mount package. Its 100 dB gain and 1.1 MHz bandwidth make it appropriate for audio-frequency signal paths, transducer conditioning, feedback networks, and low-frequency control applications. Low input bias current helps preserve measurement accuracy when the source impedance is relatively high, while the dual configuration saves board area compared with two separate single amplifiers. Each channel is independent, allowing one section to perform amplification while the other handles a different signal or a supervisory function. Because the amplifiers can operate from a single supply, the output range remains constrained by the supply rails. Designers must account for this limitation in rail-to-rail sensing applications or add suitable biasing when signals extend below the lower supply voltage. Typical uses include audio preamplification, temperature-sensor interfaces, light-control loops, low-level instrumentation, and general feedback-control systems. The 8-pin TSSOP package is useful for compact industrial, instrumentation, and embedded-control designs where two amplifiers are required but a through-hole dual operational amplifier would be unnecessarily large. Layout should keep feedback components close to the relevant input and output pins, maintain a continuous ground reference, and place decoupling capacitance near the supply pins. Input and output nodes should remain short to reduce parasitic pickup. Designers should also verify common-mode range, output swing, slew rate, supply voltage, stability, and load behavior against the manufacturer datasheet before finalizing the circuit. This product page combines manufacturer-device identification, distributor availability information, pinout and datasheet references, application guidance, and qualified same-package alternatives. It is structured to help engineers compare the LM258YPT against other 8-pin dual operational amplifiers without treating every functionally similar device as a true drop-in replacement.

LM2893M

LM2893M - 4.8 kBaud FSK Power-Line Transceiver | Texas Instruments

The Texas Instruments LM2893M is a carrier-current transceiver integrated circuit for half-duplex serial data communication over existing power lines. It combines an FSK transmitter, a receiver with phase-locked-loop demodulation, and an interface to the carrier-current network in a 20-terminal SOP package. The verified device supports data rates up to 4.8 kBaud and an operating temperature range of -40°C to +85°C. A carrier-current transceiver is a communications interface that superimposes a modulated signal onto an electrical power or communication line. In the broader electronics hierarchy, this device belongs to the interface-IC category rather than a general-purpose data converter. The LM2893M is designed to communicate short serial messages between remotely distributed nodes without requiring a dedicated signal pair, making it useful for energy-management equipment, home-automation controllers, appliance control, and industrial systems that already share a mains-powered network. The principal verified features include FSK modulation, phase-locked-loop demodulation, half-duplex bidirectional operation, a maximum data rate of 4.8 kBaud, operation from an 18 V supply, and a -40°C to +85°C industrial temperature range. Its 20-terminal gull-wing SOP package has a 1.27 mm terminal pitch according to the verified distributor listing. Because carrier-current communication is sensitive to network loading, coupling method, attenuation, noise, and grounding, successful implementation requires the interface network and filtering to be evaluated with the intended power-line environment. The LM2893M is most appropriate when both ends of a link can share a power or utility line and low data throughput is sufficient. The 4.8 kBaud rate suits status reporting, control commands, meter-reading messages, and energy-management telemetry rather than streaming data. Half-duplex operation requires the controller to avoid simultaneous transmission and to manage turnaround timing, while the PLL-based receiver provides the demodulation function required to recover FSK information from the carrier waveform. Designers should provide suitable supply bypassing and define the line-coupling, protection, filtering, and grounding arrangement with the actual mains network. Regulatory, safety, and isolation requirements must be handled by the complete interface circuit rather than assumed to be satisfied by the IC. The LM2893M itself is not a mains-isolated network interface, and its operating voltage should not be confused with the voltage appearing on the coupled power line. This page combines verified pricing, package information, operating limits, interface characteristics, and application guidance with the available manufacturer-family relationship. It also documents the absence of verified drop-in equivalents instead of presenting unverified substitutes as production-ready replacements.

LM2893N

LM2893N - Carrier-Current Transceiver | National Semiconductor

National Semiconductor LM2893N is a one-transceiver carrier-current interface IC designed for half-duplex, bidirectional serial communication over an existing power-mains network. The device is offered in a 20-pin PDIP package and combines a transmitter and receiver in one integrated circuit. Carrier-current systems use power-line infrastructure to transfer information between remotely separated locations rather than requiring a separate communication cable. A carrier-current transceiver is a type of power-line interface IC. Carrier-current communication belongs to the broader power-line networking and interface IC hierarchy, where communication signals are superimposed on an electrical power conductor. The LM2893N is intended to interface a serial data source with a carrier-current network, making it useful where the mains wiring already extends between remote nodes and adding a separate low-speed communication route would be impractical. The verified source information identifies the LM2893N as a one-transceiver, 20-PDIP device for carrier-current systems. Its principal benefit is integration: both directions of the half-duplex link are handled by a single package instead of separate transmitter and receiver packages. The confirmed communication mode is bidirectional and serial, allowing a node to exchange bit-stream data with another node over the same carrier-current medium. The LM2893N belongs to the bipolar LM1893/LM2893 carrier-current transceiver family. This family positioning indicates that the LM2893 is the higher-temperature-oriented member relative to the LM1893 designation, although exact electrical limits and comparison values are not included in the supplied distributor data. Designers should use the manufacturer datasheet for voltage ratings, current limits, logic thresholds, transmission timing, receiver sensitivity, and network-interface details before releasing production hardware. Typical carrier-current uses include remote metering, building-management communication, industrial monitoring, appliance control, and low-speed supervisory links where power and data share the same wiring. In these systems, the LM2893N acts as the physical-layer interface between the communication network and the node's serial logic. Network loading, isolation requirements, coupling method, transmit power, and protocol timing remain application-specific. The principal design consideration is that carrier-current communication is materially different from ordinary RS-485 or isolated digital communication. The power conductor presents a difficult noise environment, and the interface network must be characterized for attenuation, impedance, coupling, and surge exposure. PCB grounding, filtering, isolation boundaries, and protection components therefore deserve attention before the communication protocol is finalized. This product page combines verified distributor identification, family-level technical context, package information, sourcing links, and structured engineering guidance that is not available in a basic distributor listing. Exact electrical specifications and qualified drop-in replacements remain explicitly separated from verified facts so engineers can make a safe replacement decision without relying on assumptions.

The part is intended for general-purpose analog signal conditioning rather than precision instrumentation or automotive-qualified systems. According to the Texas Instruments LM2900 product page, the LM2900 family consists of four independent, high-gain frequency-compensated Norton operational amplifiers designed to operate from a single supply over a wide range of voltages. The product description also identifies large output-voltage swing, output short-circuit protection, internal frequency compensation, and low input bias current as important characteristics. These features make the device suitable for buffering, voltage amplification, signal conditioning, and general feedback-control circuits. The LM2900D can be used with a single positive supply or with split supplies. In single-supply designs, the input and output signal levels must remain within the amplifier's common-mode and output-swing limits. The LM2900 family is internally frequency compensated, so the feedback network establishes the closed-loop gain without requiring a separate compensation capacitor in ordinary applications. The 14-pin SOIC package provides a conventional surface-mount footprint and a practical temperature range for industrial and consumer equipment. Typical uses include transducer-signal conditioning, sensor interfaces, audio preamplification, low-current feedback amplifiers, and general analog control loops. Because the verified data does not provide detailed electrical limits, bandwidth, noise, slew rate, or exact input/output range, those parameters should be confirmed in the manufacturer datasheet before final design release.

LM2900N

LM2900N - Quad 2.5MHz Norton Operational Amplifier | TI

The Texas Instruments LM2900N is a quad, high-gain, frequency-compensated Norton operational amplifier with four independent amplifiers in a 14-pin PDIP package. Its headline specifications include a 2.5 MHz gain-bandwidth product, 20 V/µs slew rate, 4.5 V to 32 V single-supply operation, and ±2.2 V to ±16 V dual-supply operation. An operational amplifier is an analog signal-conditioning IC that uses high open-loop gain to amplify the difference between two input voltages. The LM2900 belongs to the Norton-operational-amplifier family, characterized by current-feedback-style input stages. Within the broader electronics hierarchy, it is an analog amplifier IC, then an operational amplifier, then a general-purpose quad amplifier. The LM2900 provides four independent amplifiers, wide bandwidth, large output-voltage swing, short-circuit protection, internal frequency compensation, and low input-bias current. Internal compensation removes the need for external compensation components in ordinary closed-loop operation, simplifying analog boards that need several amplified signals on one supply rail. Its specified 4.5 V to 32 V single-supply range makes it applicable to legacy industrial control, instrumentation, sensor interfaces, audio, and communications equipment. The 20 V/µs slew rate supports faster edge rates than many general-purpose amplifier selections, while the 2.5 MHz bandwidth gives useful signal bandwidth for audio and control applications. The DIP package also supports through-hole assembly and socketed prototypes. When designing around the LM2900N, verify input and output common-mode limits at the selected supply voltage. Account for the input-bias current when driving high-impedance sensors, and use stable feedback networks with resistive isolation where required by the source impedance. The device uses four independent amplifiers, but shared-package power and ground connections still require careful layout.

LM2901D

LM2901D - 30V Quad Differential Comparator | Texas Instruments

The Texas Instruments LM2901D is a 30 V quad differential comparator containing four independent open-collector comparator channels in a 14-pin SOIC package. Each channel supports single or split-supply operation, while the device is designed for level detection, low-level sensing, memory, consumer, automotive, and industrial applications. The LM2901D combines a typical input bias current of 25 nA with a typical input offset current of ±5 nA. A comparator is an analog integrated circuit that evaluates two input voltages and produces a logic-level result indicating which input is higher. Within the semiconductor hierarchy, the LM2901D is a voltage comparator, a linear signal-conditioning IC commonly grouped with amplifier and interface functions. Its open-collector outputs require an external pull-up resistor, allowing several outputs to be wired together when the resulting wired-AND behavior is appropriate for the system. The four independent channels make the LM2901D useful where several sensing decisions must be made in one package. Its open-collector output structure can drive TTL, CMOS, MOS, DTL, and ECL-compatible logic as identified in the manufacturer literature. The specified 300 ns response time supports general-purpose detection rather than the latency demanded by high-speed timing applications. Split-supply operation also permits bipolar sensing around a zero-volt reference. The input stage emphasizes low bias current, which reduces disturbance of high-impedance sensor outputs. A typical 25 nA input bias current is suitable for many threshold and level-detection circuits, while the typical ±5 nA input offset current helps minimize imbalance between the differential inputs. These characteristics should be considered together with input common-mode limits, output pull-up requirements, and supply-voltage tolerances during design verification. Typical uses include monitoring battery or power rails, detecting overvoltage and undervoltage conditions, comparing sensor thresholds, implementing window comparators, and providing four-channel status indication. Because all four outputs are open collector, a pull-up resistor is normally required on each channel. Connecting multiple open-collector outputs to one pull-up can reduce the number of logic signals, but it also creates a shared fault domain and requires careful analysis of output leakage and pull-up current. A practical design must preserve adequate input common-mode headroom at both supply rails, keep differential input voltage within the absolute maximum limits, and select pull-up resistors for the voltage and sink-current requirements of the connected logic. Decoupling capacitors should be placed close to the supply pins, while unused comparator inputs should be tied to a defined potential rather than left floating. This page organizes the key LM2901D electrical characteristics, manufacturer-backed comparison options, pin-package constraints, and application guidance for engineers evaluating a 14-pin quad comparator. It also highlights the practical trade-offs involved when selecting a drop-in alternative with different input offset, bias current, temperature range, or propagation timing.

LM2901M

LM2901M - 4-Channel 36V Open-Collector Comparator | Texas Instruments

Texas Instruments LM2901M is a four-channel differential analog comparator with an operating supply range of 2 V to 36 V, a typical response time of 1.3 µs, and open-collector outputs in a 14-pin SOIC package. Designed for single-supply operation, it can also operate from dual supplies providing approximately ±1 V to ±18 V. Each comparator compares two input voltages and produces a digital result that can drive TTL, MOS, or CMOS-compatible logic. The package is identified by the M suffix and is suitable for conventional through-hole PCB assembly when surface-mount assembly is not required. An analog comparator is a semiconductor that converts the relationship between two voltages into a logic-level output. The LM2901 belongs to the comparator hierarchy, where a general-purpose comparator is used for threshold detection, signal conditioning, and industrial control rather than precision analog amplification. Its wide supply range, low input bias current, and low typical supply-current consumption make it suitable for systems operating from low-voltage control circuits through higher-voltage industrial environments. The principal features include four independent comparator channels, an approximate 36 V maximum supply, 800 µA typical supply-current drain, 25 nA typical input bias current, and open-collector outputs suitable for wired logic. These characteristics allow the device to monitor slow and fast control signals while maintaining low loading on high-impedance sensor nodes. The open-collector architecture also supports wired-AND behavior when multiple comparators share a pull-up resistor, although the common output node requires careful voltage and timing analysis. Each internal comparator has an inverting input, a non-inverting input, and an open-collector output. The open-collector transistor normally remains off, so an external pull-up resistor is required to establish a high output state. When the comparator output is pulled low, the output transistor sinks current from that pull-up network. The resulting interface can support wired logic, relay-driver stages, lamp indicators, and other systems where a pulled-up bus must be shared safely. Typical applications include industrial sensor-limit detection, overvoltage and undervoltage monitoring, battery threshold detection, control-system interlock circuits, and logic-level translation around higher-voltage signals. The four channels can be used independently, or several channels can implement window comparison, fault detection, and redundant monitoring functions. A common ground and supply arrangement simplifies multi-channel designs while requiring attention to common-mode limits, output pull-up placement, and input protection. The principal design consideration is ensuring that input and output conditions remain within the comparator's absolute maximum and common-mode limits. Input protection may be required when external wiring exposes the device to transients or voltages outside the normal operating range. The open-collector outputs also need suitable pull-up resistors, with resistance selected from the required sink-current, rise-time, and bus-loading constraints rather than from resistance alone. This page combines manufacturer specifications, verified distributor information, pin-level implementation guidance, and same-footprint replacement analysis. It also identifies the practical trade-offs among closely related LM2901-family ordering options so that engineers can distinguish electrical compatibility, package identity, and qualification differences before committing a design to production.
