LM201AH - 1 MHz General-Purpose Op Amp | Texas Instruments
Teilenummer: LM201AH ✓ AktivLM201AH Übersicht
An operational amplifier, or op amp, is a high-gain differential-input amplifier whose feedback network determines its closed-loop behavior. The LM201AH belongs to the general-purpose operational-amplifier class within the broader amplifier IC and signal-conditioning hierarchy. Its TO-99-8 construction provides a through-hole package option for laboratory, industrial, and legacy instrumentation designs where surface-mount compatibility is not required.
The principal performance features include a 1 MHz gain-bandwidth product, 80 dB CMRR, 2 mV input offset voltage, and approximately 1.8 mA operating current. The wide common-mode rejection specification helps reduce unwanted behavior when the amplifier handles small signals superimposed on larger voltage references or sensor outputs. The hermetic TO-99-8 package supports applications requiring a conventional metal-can outline and eight through-hole connections.
The LM201A family uses advanced processing to reduce input bias current and temperature drift while retaining the general-purpose characteristics of the earlier LM101A architecture. The device can operate with conventional dual power supplies, making it suitable for signal paths centered around ground. Engineers should nevertheless verify supply-voltage limits, input common-mode range, output swing, compensation requirements, and electrical limits against the manufacturer datasheet before finalizing a design.
Typical uses include laboratory instrumentation, analog measurement front ends, active filters, transducers, current-sensing amplifiers, and precision feedback loops. In a filter or amplifier, its 1 MHz gain-bandwidth product limits usable closed-loop bandwidth according to the selected noise-gain configuration. For sensor interfaces, the 80 dB CMRR can help reject common-mode interference, while the 2 mV offset remains an important error term in precision measurements.
When designing around the LM201AH, begin by checking the required output swing and input common-mode range at the actual supply voltage. Decoupling should be placed close to the power pins, and the circuit should avoid driving capacitive loads unless stability behavior has been evaluated. Because the exact pin names and electrical limits are not included in the supplied search excerpts, those details should be confirmed in the Texas Instruments LM201A-N documentation before PCB release.
This page consolidates the supplied distributor and manufacturer listings with practical selection guidance, package-aware alternatives, comparison parameters, and design cautions. It distinguishes confirmed data from unavailable fields so engineers can verify critical specifications without relying on assumptions.

Typische Anwendungen
LM201AH ist geeignet für 6 Anwendungs: Laboratory Instrumentation Signal Conditioning, Precision Analog Measurement, Active Filtering and Signal Conditioning, Current Sensing and Feedback Control, Industrial Transducer Interface, Legacy Audio and Control Circuits.
Laboratory Instrumentation Signal Conditioning
The LM201AH fits laboratory instrumentation because its 1 MHz gain-bandwidth product supports general-purpose amplification and its 80 dB CMRR helps suppress common-mode voltage on small sensor signals. A typical circuit uses the amplifier in a non-inverting or differential conditioning stage followed by an ADC or meter. The 2 mV input offset must be included in the error budget, while the approximately 1.8 mA supply current keeps auxiliary analog circuitry relatively economical. Before implementation, verify the exact input common-mode range, output swing, and supply limits from the LM201A-N datasheet.
Empfohlen
Precision Analog Measurement
The LM201AH can amplify weak measurement signals when its 2 mV input offset and 80 dB CMRR meet the required accuracy budget. It is suitable for closed-loop measurement stages that sense near-ground bipolar signals because the LM201A family is intended for conventional dual-supply operation. The 1 MHz gain-bandwidth product is adequate for many moderate-bandwidth sensors, but filtering, settling time, and output-drive requirements must be checked at the selected closed-loop gain. The hermetic TO-99-8 package also suits legacy laboratory and industrial instruments requiring through-hole construction.
Empfohlen
Active Filtering and Signal Conditioning
The LM201AH is appropriate for active filters and general signal-conditioning networks because the manufacturer describes the LM201A family as a general-purpose operational amplifier with 1 MHz gain-bandwidth product. In a low-pass, high-pass, or differential filter, usable bandwidth depends on closed-loop gain and the required noise gain rather than the gain-bandwidth value alone. Designers should verify phase margin, output swing, and capacitive-load behavior in the manufacturer documentation. The 80 dB CMRR can improve rejection of common-mode interference when the filter processes balanced or differential signals.
Empfohlen
Current Sensing and Feedback Control
The LM201AH can implement a current-sense amplifier or precision feedback element when its offset and bandwidth are adequate for the control loop. Its 2 mV input offset produces a sensing error proportional to the shunt voltage, while the 1 MHz gain-bandwidth product limits response speed. In a power-control application, engineers must account for supply limits, output saturation, input common-mode range, and stability during startup. The approximately 1.8 mA operating current is useful when the amplifier is continuously active, although overall power depends on the selected supply voltage.
Empfohlen
Industrial Transducer Interface
The LM201AH is suitable for industrial transducer interfaces that require general-purpose amplification of slowly varying or moderate-frequency sensor outputs. Its 80 dB common-mode rejection helps reject differential interference, while the single-circuit TO-99-8 package supports high-voltage board layouts and through-hole assembly. The -40 °C to +85 °C listed range covers many industrial environments, but the enclosure, creepage, noise sources, and grounding must still be controlled. Confirm input bias current and offset drift against the sensor impedance before selecting resistor values and capacitors.
Empfohlen
Legacy Audio and Control Circuits
The LM201AH can serve in legacy audio preamplifier, mixing, and servo-control circuits where the original design specified a hermetic TO-99 operational amplifier. Its 1 MHz gain-bandwidth product provides useful bandwidth for general audio and control paths, while the 80 dB CMRR reduces common-mode conversion in balanced stages. The 2 mV offset may contribute to audible or measurable DC error in high-gain audio paths, so coupling and biasing require care. Designers should also verify slew rate, output swing, noise, and stability because these values were not present in the supplied excerpts.

Wichtigste Unterscheidungsmerkmale

- Defined 2 mV input offset specification (vs. LM101AH)
- Lower documented operating current than many conventional alternatives (vs. Am301A)
Designhinweise
Do not treat a shared TO-99-8 outline as proof of complete electrical equivalence. The verified comparison between LM201AH and LM101AH explicitly indicates that some electrical characteristics differ, while the AMD documentation describes Am101A, Am201A, and Am301A as pin-for-pin equivalents to their corresponding National Semiconductor families rather than identical devices. Before replacing LM201AH, compare supply voltage, common-mode range, output swing, input offset, bias current, slew rate, compensation method, and noise against the complete manufacturer datasheets.
The listed supply current of approximately 1.8 mA is a useful baseline, but actual dissipation depends on the voltage applied to both supply pins. Place a local bypass capacitor at the positive supply connection and return it directly to the ground or negative-supply reference recommended by the manufacturer guidance. Keep sensitive input and feedback nodes away from the bypass-capacitor return path so supply-current changes and shared-impedance noise do not degrade the 80 dB common-mode rejection performance.
Calculate usable bandwidth from the desired closed-loop gain or noise gain rather than treating the 1 MHz gain-bandwidth product as the final filter cutoff. Include phase margin and settling requirements, especially in instrumentation paths with long feedback traces. Keep the inverting input and feedback components compact, use a ground plane for return current, and avoid routing the signal trace adjacent to power-supply paths or the TO-99 leads carrying high slew-rate output current.
The hermetic TO-99-8 package requires a through-hole footprint rather than a surface-mount land pattern. Confirm pin numbering directly from the LM201A-N datasheet because the supplied excerpts establish eight pins but do not provide the individual names. Maintain adequate spacing around the metal can for mechanical tolerance, avoid excessive force on the pins during assembly, and use a clean ground connection so the single-channel device can preserve its specified CMRR in practical layouts.
Compliance-Informationen
The supplied excerpts do not contain verified environmental or automotive-compliance declarations for LM201AH. The LM201AH/NOPB ordering code appears in the verified results, but it alone is not treated as proof of every compliance category.
