LM201AD - 1 MHz Single Op Amp, 8-SOIC | STMicroelectronics
MPN: LM201AD ✗ জীবনকালের সমাপ্তিLM201AD সারাংশ
An operational amplifier is an analog signal-conditioning integrated circuit that amplifies the voltage difference between its inverting and non-inverting inputs. The LM201 family is positioned as a general-purpose amplifier rather than a precision micropower device or a high-speed rail-to-rail amplifier. Its non-compensated architecture requires the user to add external compensation when closed-loop stability is needed, making it most suitable for designs in which the engineer selects a specific gain, bandwidth, and phase-margin target.
Verified distributor information identifies the LM201AD as a one-amplifier, 8-SOIC device. One distributor listing reports a 1 MHz gain-bandwidth product, while a separate Mouser listing identifies a 3.5 MHz gain-bandwidth figure. These values may reflect different source pages or gain and condition definitions, so the two figures should be confirmed against the exact STMicroelectronics datasheet revision before setting compensation networks or estimating closed-loop bandwidth.
Typical uses include general analog signal conditioning, instrumentation interfaces, active filtering, and feedback control in industrial or test equipment where higher supply voltages are acceptable. Because this is a non-compensated amplifier, external compensation components and stability analysis are normally required. The wide plus or minus 22 V capability also makes rail-to-rail input and output operation unlikely, so input and output common-mode and swing limits must be respected.
For PCB design, place the amplifier close to feedback and compensation components, keep input nodes away from switching nodes and high-current paths, and provide adequate ground return connectivity for the single-supply return terminal. Decoupling requirements should be confirmed from the manufacturer datasheet rather than inferred from the distributor listings.
This page combines verified distributor specifications, package information, cross-reference results, and engineering guidance that are not consolidated in a single manufacturer product listing. Pricing, pin-level data, lifecycle details, and compensation requirements should be verified against the current STMicroelectronics datasheet before production release.

সাধারণ ব্যবহার
LM201AD এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: General-Purpose Analog Signal Conditioning, Instrumentation Amplifier Front End, Active Analog Filter, Feedback Control Amplifier, Laboratory Test and Measurement, High-Voltage Industrial Sensor Interface.
General-Purpose Analog Signal Conditioning
The LM201AD fits general analog signal-conditioning stages that require one operational amplifier, push-pull output, and a supply range extending to plus or minus 22 V. Its non-compensated architecture allows the engineer to select external compensation for the intended closed-loop gain rather than accepting a fixed internal network. The verified 0.5 V/us slew rate is suitable for moderate-bandwidth instrumentation signals, while the wide supply capability permits use in higher-voltage industrial test circuits. Before finalizing the design, confirm input offset voltage, bias current, noise, common-mode range, and output swing from the exact manufacturer datasheet.

Instrumentation Amplifier Front End
The LM201AD can serve as an intermediate amplifier stage in a discrete instrumentation front end when the sensor output requires level shifting, filtering, or drive into a higher-impedance measurement block. The verified plus or minus 5 V to plus or minus 22 V supply range provides flexibility for laboratory and industrial excitation circuits, and the push-pull output is useful for driving the next stage. Because the device is non-compensated, the selected gain must be paired with a verified compensation network, and input bias current must be checked against sensor source impedance to prevent DC error.

Active Analog Filter
The LM201AD is applicable to active-filter prototypes that require an externally compensated amplifier and a conventional single-amplifier topology. Its non-compensated nature can support deliberate pole placement and bandwidth selection, but the exact component values depend on the target gain, closed-loop bandwidth, phase margin, and load. The 1 MHz figure in the FindIC listing and the 3.5 MHz figure in the Mouser listing must be reconciled before calculating compensation. Bench validation with the selected tolerance stack is recommended because noise, offset, bias current, and gain-bandwidth details were not captured in the verified data.

Feedback Control Amplifier
The LM201AD can function in a feedback-control loop where a stable, compensated amplifier is preferred over a fixed-compensation device. Its wide plus or minus 5 V to plus or minus 22 V supply capability permits operation from higher-voltage industrial control rails, and the single 8-SOIC package simplifies point-to-point or multichannel board layouts when replicated. Loop stability and transient response require careful compensation design around the measured gain-bandwidth behavior. Check the load capability and output swing against the actuator or feedback network before using the device in closed-loop service.
সুপারিশকৃত
Laboratory Test and Measurement
The LM201AD is a reasonable candidate for laboratory test and measurement fixtures that operate from higher-voltage analog rails and require flexible closed-loop gain. The verified 8-SOIC package and push-pull output make it practical for breadboarded or compact instrument modules, while the 300 mW dissipation listing identifies thermal consideration for sustained operation. Engineers should verify maximum input and output swing, supply-current behavior, stability, and temperature limits before installation. A shielded layout with short feedback paths reduces noise pickup and reduces the risk of unintended oscillation.
সুপারিশকৃত
High-Voltage Industrial Sensor Interface
The LM201AD can be evaluated for industrial sensor-interface circuits where available supply headroom exceeds the requirements of low-voltage rail-to-rail amplifiers. Its plus or minus 22 V maximum listed supply and push-pull output permit compatibility with higher-voltage bias networks, while the non-compensated design enables application-specific stabilization. Input protection and actual signal swing remain essential constraints, and common-mode limits must be obtained from the datasheet. Use a protected layout with defined return paths and confirm that transient levels at the pins remain within the manufacturer limits.

ডিজাইন নোট
Do not treat the LM201AD as a unity-gain-stable amplifier without verifying its compensation arrangement. The verified manufacturer description identifies it as non-compensated, so the external compensation network must be chosen for the intended closed-loop gain and load. Also reconcile the conflicting 1 MHz and 3.5 MHz distributor gain-bandwidth figures before calculating poles or phase margin. Use the exact STMicroelectronics datasheet and validate the completed filter or amplifier with a scope and a stability probe.
Keep the operational amplifier, feedback components, and compensation capacitor in a compact loop near the SOIC pins. Route both inputs away from switching nodes, relay contacts, high-current return paths, and the device's own output node. Use a continuous ground plane and short, direct return paths for bypass capacitors. Because the LM201AD supports plus or minus 22 V supply listings, check that no external node exceeds the actual input, output, and absolute-maximum limits specified by the manufacturer.
Estimated: using the verified 300 mW dissipation value as the reference condition, actual self-heating depends on supply voltage, output swing, load current, ambient temperature, and PCB copper. The supplied data does not include a thermal-resistance figure, so junction temperature cannot be calculated reliably. Derive dissipation from the actual operating values, confirm the package thermal data, and provide adequate copper area. Avoid extrapolating the distributor dissipation figure as a universal operating limit.
কমপ্লায়েন্স তথ্য
The verified snippets identify PbAHP compliance for the compared LM201AD versus LM201ADT entry, but they do not provide a complete current RoHS, REACH, AEC-Q100, halogen-free, or conflict-minerals declaration for the target orderable part. AEC-Q100 is marked not applicable because this is a general-purpose analog amplifier and no automotive qualification was provided.
