MCP601-I/ST - 2.7V Rail-to-Rail CMOS Op Amp | Microchip
MPN： MCP601-I/ST ✓ 啟用中MCP601-I/ST 概覽
A CMOS operational amplifier is an analog building block that uses high input impedance and voltage gain to amplify small signal differences. The MCP601 belongs to the operational-amplifier hierarchy, which connects to analog signal-processing ICs and broader semiconductor systems. Its CMOS construction is intended to support low power consumption, low input bias current, and operation from low-voltage supplies while preserving useful open-loop gain.
The manufacturer identifies the MCP601 family as a low-power operational amplifier with rail-to-rail output swing. This output capability is useful when the usable output range must extend close to either supply rail. The family also supports operation with supply voltages as low as 2.7 V and draws less than 325 uA of quiescent current according to the Microchip product page. These characteristics make it useful in battery-operated and portable equipment where every milliamp of supply demand can affect runtime.
The MCP601-I/ST uses Microchip's advanced CMOS process technology. Publicly indexed product information describes low bias current, high-speed operation, and high open-loop gain. These properties support sensor conditioning, buffering, and low-level signal amplification, although exact gain-bandwidth, slew-rate, input-bias-current, and offset figures are not included in the supplied verified records and therefore remain marked for data retrieval.
Typical uses include portable sensor interfaces, low-voltage instrumentation, audio signal conditioning, and general-purpose analog buffers. In a sensor interface, the amplifier can sit between a high-impedance transducer and a downstream ADC. In a battery-powered circuit, its sub-325 uA quiescent current and 2.7 V minimum operating supply help conserve available energy. Its rail-to-rail output reduces the headroom required when driving a following stage.
Designers should verify the complete electrical limits and stability requirements against the manufacturer datasheet before production use. Decoupling capacitors, source impedance, output loading, and the selected gain can affect practical performance. The 8-pin TSSOP footprint is compact, but the exposed thermal limitations and assembly requirements of this small package should be considered alongside ambient temperature and expected dissipation.
This page consolidates the verified distributor listing, manufacturer family information, package identification, current pricing reference, and practical selection context. It also distinguishes confirmed drop-in options from package variants that require PCB consideration, helping engineers compare replacements without treating electrically similar parts as automatically interchangeable.

典型應用
MCP601-I/ST 適用於 6 應用s: Battery-Powered Sensor Interface, Portable Medical Monitoring, Low-Voltage Audio Buffering, Industrial Control Signal Conditioning, Data Acquisition Front End, IoT Edge Sensor Hub.
Battery-Powered Sensor Interface
The MCP601-I/ST fits low-voltage sensor interfaces because its documented 2.7 V minimum operating supply and less than 325 uA quiescent current help preserve battery energy. Place the amplifier between a high-impedance sensor and a downstream ADC, using the rail-to-rail output where the signal must approach a supply limit. The benefit is a compact single-supply signal path suitable for portable instrumentation, although the complete battery budget must include sensor and ADC consumption. Exact capacitor recommendations and input-noise data should be confirmed in the manufacturer datasheet before layout release.
推薦
Portable Medical Monitoring
The MCP601-I/ST can support compact medical-monitoring signal paths that operate from a single low-voltage rail. Its single-circuit CMOS architecture, low input bias current, and rail-to-rail output are useful when conditioning a sensor-derived waveform before digitization. The 2.7 V to 5.5 V supply range supports portable devices that prioritize low component count and low quiescent demand. For diagnostic or life-critical use, engineers must independently verify patient-safety requirements, isolation, accuracy, and applicable regulatory standards rather than assuming a general-purpose op amp is qualified.
推薦
Low-Voltage Audio Buffering
The MCP601-I/ST is applicable in small audio and microphone circuits where a single 2.7 V to 5.5 V supply limits available output swing. Rail-to-rail output helps preserve low-level audio signal range, while the family's low bias current is favorable for high-impedance sources. The amplifier can buffer a microphone or line-stage output before an ADC or codec. Its exact bandwidth, slew rate, noise, and output-drive capability are not included in the supplied records, so frequency response and distortion requirements must be checked against the complete Microchip datasheet.
推薦
Industrial Control Signal Conditioning
The MCP601-I/ST can condition low-level control and sensor signals in compact industrial electronics powered from a 5 V or lower rail. Its single-supply operation and rail-to-rail output simplify interfacing between a sensor and a controller input, while the 8-lead TSSOP package supports dense layouts. The -I/ST ordering variant is associated with an extended industrial temperature grade, although the verified records do not state the numerical limits. Confirm those limits, along with noise, offset, common-mode behavior, and stability, before using the device in safety-critical control loops.
推薦
Data Acquisition Front End
The MCP601-I/ST is suitable as an input buffer or gain stage in compact data-acquisition systems powered by a 2.7 V to 5.5 V rail. The low-power CMOS design can reduce the load presented by a high-impedance sensor, and rail-to-rail output provides more of the available signal span before conversion. A practical design should verify input offset, bias current, noise, gain-bandwidth product, and common-mode limits because those numerical parameters were not supplied in the verified web records. The same-family SOIC and PDIP versions can simplify breadboard validation before the TSSOP layout is finalized.
推薦
IoT Edge Sensor Hub
The MCP601-I/ST fits IoT edge-sensor circuits that must amplify a weak analog signal before digital conversion while operating from a restricted power budget. Its less-than-325 uA manufacturer-stated quiescent current and 2.7 V minimum supply are beneficial in compact edge nodes. Rail-to-rail output can reduce headroom loss into a low-voltage ADC. Designers should account for the amplifier's unspecified noise and offset values, sensor settling time, and the ADC's acquisition requirements. A common-ground, short-trace layout and datasheet-recommended bypass placement are essential for predictable behavior in a compact IoT module.

主要差異化特點
- Manufacturer-documented low-voltage operation (對比MCP6001-I/ST)
- Confirmed rail-to-rail output capability (對比MCP6001-I/ST)
- Low quiescent demand (對比MCP6001-I/ST)
設計說明
Budget the MCP601-I/ST against the complete analog subsystem rather than using its less-than-325 uA quiescent current as the total circuit demand. Sensor biasing, ADC operation, and amplifier output current can dominate consumption. The 2.7 V to 5.5 V single-supply range simplifies low-voltage designs, but the selected bypass capacitors and regulator must remain stable with the amplifier's operating current.
Keep the supply bypass path and any required output-decoupling component close to the corresponding MCP601-I/ST pins. Use a low-resistance ground return and avoid routing sensitive input traces beneath the package. The supplied records do not specify capacitor values or maximum input-capacitance guidance, so those details must be taken from the manufacturer datasheet before finalizing the layout.
Do not treat the 2.7 V minimum supply as permission to operate below the full electrical limits or to assume the output can reach both supply rails exactly. Rail-to-rail output describes the output capability, not zero headroom. Account for load current, output swing, input common-mode range, and downstream ADC limits. Also compare temperature-grade suffixes before replacing MCP601-I/ST with MCP601-E/ST.
合規資訊
The supplied verified records do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because MCP601-I/ST is a general-purpose amplifier and no automotive qualification was identified.
