LM2902N 概要
An operational amplifier is an analog integrated circuit that uses differential input and feedback to control an output voltage. In the broader electronics hierarchy, an op amp belongs to the amplifier-IC family, performs closed-loop signal amplification, and commonly supports filtering, buffering, level shifting, sensing, and control applications. A quad package provides four amplifiers in one IC, reducing component count while preserving separate signal paths where independent channels are useful.
The verified product information specifically describes the LM2902-N as a quad 26 V, 1 MHz operational amplifier. The LM2902 family is associated with wide single-supply operation, internally frequency-compensated amplifiers, and general-purpose analog designs. These characteristics are useful when a board needs four amplifier channels with moderate bandwidth rather than a high-speed precision device. Because the available data does not provide the complete electrical tables, detailed input-bias-current, output-swing, noise, and common-mode specifications must be verified in the manufacturer datasheet before production release.
Typical uses include sensor conditioning, low-frequency active filters, industrial control loops, audio preamplifier stages, and general-purpose analog signal paths. The 14-pin DIP outline is appropriate when the design uses a through-hole footprint or a manually assembled educational or industrial prototype. Designers should confirm the exact pinout, supply limits, common-mode range, output drive, and stability requirements for the intended operating point rather than relying only on the family-level description.
A key design consideration is decoupling: place the supply bypass capacitor close to the device power pins and provide a stable, low-impedance return path. Input and feedback components should be arranged to minimize parasitic pickup and unwanted oscillation. This page distinguishes verified LM2902-N facts from unspecified parameters, making it a practical starting point for procurement and engineering review.
The LM2902N combines four channels, a 26 V supply class, and a 1 MHz operating-speed class in a through-hole 14-pin DIP. This combination supports cost-sensitive analog designs where external compensation, rail-to-rail operation, or high bandwidth is not required.

主な用途
LM2902N の用途: 6 件s: Industrial Sensor Signal Conditioning, Low-Frequency Active Filters, Audio Preamplifier Stages, Motor and Power-Control Loops, Test and Measurement Buffering, Educational and Prototype Analog Circuits.
Industrial Sensor Signal Conditioning
The LM2902N is a practical choice for conditioning slow sensor signals when the design needs four amplifier channels, a 26 V supply class, and a 1 MHz operating-speed class. Each independent channel can support buffering, gain shaping, or active filtering around sensors such as temperature, pressure, and position devices. The DIP package is convenient for industrial prototype boards and through-hole control assemblies. The main tradeoff is that the verified data does not specify offset, bias current, noise, common-mode range, or output swing, so sensor accuracy and signal headroom must be checked against the selected manufacturer datasheet.
おすすめ
Low-Frequency Active Filters
LM2902N can form the active stage of low-frequency filters in audio, measurement, and control circuits. Its stated 1 MHz class is sufficient for many modest-bandwidth filter sections, while four channels allow second-order or multi-stage filtering without requiring four separate packages. Use stable feedback resistors and capacitors and keep sensitive input nodes compact to reduce noise pickup. The supplied information does not identify the exact compensation, gain-bandwidth curve, or slew rate, so filter Q and stability must be verified in the manufacturer datasheet and tested with the intended component tolerances.
おすすめ
Audio Preamplifier Stages
The LM2902N can be evaluated for line-level audio preamplification or small-signal conditioning when four channels and a through-hole DIP package simplify assembly. Its 1 MHz operating-speed class is well above many low-frequency audio tasks, while the general-purpose architecture supports ordinary feedback-based gain stages. The verified source does not provide input-referred noise, harmonic distortion, input impedance, or output-drive data, so it should not be selected solely for audio-quality requirements without reviewing the complete TI or manufacturer datasheet and measuring the finished gain path.
おすすめ
Motor and Power-Control Loops
LM2902N is suitable for preliminary design work in low-bandwidth motor-control and power-control loops where four general-purpose amplifier channels and a 26 V supply class are useful. A typical arrangement may use channels for error amplification, current or position conditioning, and output buffering. Because the available data does not establish response time, output current, input common-mode limits, or thermal limits, engineers should calculate loop bandwidth and drive requirements before selecting it. The DIP package is useful for prototypes, but a production design should also review creepage, noise, and environmental qualification.
おすすめ
Test and Measurement Buffering
LM2902N can buffer moderate-bandwidth measurement signals when a design needs four amplifier channels and conventional through-hole assembly. It may be used ahead of an analog measurement front end, around resistive dividers, or in feedback stages of an instrumentation amplifier topology. The verified 26 V and 1 MHz classes provide the starting point for a general-purpose design, but input bias current, offset voltage, output impedance, and common-mode range are not present in the supplied data. Verify those parameters against the actual source and manufacturer, and check settling behavior before using it in precision measurement paths.
おすすめ
Educational and Prototype Analog Circuits
LM2902N is a practical teaching and prototyping part because it combines four general-purpose amplifiers, a 14-pin DIP package, and a single-supply-oriented architecture. Students and engineers can use the channels to demonstrate non-inverting and inverting amplifiers, comparators, integrators, oscillators, filters, and feedback control without assembling four separate ICs. The package is easy to insert into breadboards and through-hole training boards. Before drawing conclusions about rail-to-rail behavior, noise, or precision, consult the exact manufacturer datasheet because those parameters are not specified in the supplied search results.

設計ノート
Place the supply bypass capacitor close to the LM2902N power pins and use a low-impedance ground return. The verified family information supports single-supply operation, but the exact allowable supply and common-mode ranges are not included in the supplied data. Before layout release, verify those limits against the selected manufacturer datasheet and ensure the input/output operating points remain inside the supported rails.
Keep the 14-pin DIP footprint and its pin numbering consistent with the exact manufacturer being sourced. Do not assume that the same suffix from different manufacturers is interchangeable without comparing the pinout and electrical tables. Route feedback and compensation components close to the relevant pins, and avoid long high-impedance traces that can increase noise pickup or reduce stability in the closed-loop amplifier.
Do not choose LM2902N only from its 26 V and 1 MHz family-level claims. Input offset, input bias current, common-mode range, output swing, noise, slew rate, temperature rating, and stability conditions are not present in the supplied excerpts. Verify those parameters in the official datasheet, especially for precision sensing, high-load drive, battery operation, or industrial temperature-range requirements.
コンプライアンス情報
The supplied verified search results do not provide compliance declarations for the LM2902N. Confirm RoHS, REACH, lead-free, halogen-free, and conflict-mineral status with the selected manufacturer.
