MCP624-E/ST

MCP624-E/ST - 20MHz Quad mCal Op Amp | Microchip Technology

Microchip Technology MCP624-E/ST is a quad general-purpose operational amplifier with a 20 MHz gain-bandwidth product, 10 V/us slew rate, rail-to-rail input and output capability, and four amplifiers in a 14-pin TSSOP package. The device includes Microchip mCal self-calibration to reduce input offset voltage at power-up. An operational amplifier, or op amp, is a high-gain analog building block used to amplify, buffer, filter, compare, and drive signals. The MCP624 belongs to the CMOS operational-amplifier hierarchy, where rail-to-rail input and output operation supports signals approaching the supply rails. Four independent channels in one package can simplify sensor conditioning, signal conditioning, and general analog signal-chain designs while reducing board area. The MCP624-E/ST provides a typical 20 MHz gain-bandwidth product, 10 V/us slew rate, 13 nV/Hz typical noise at 1 MHz, and a typical short-circuit current of 70 mA. Its calibrated input offset voltage is specified at a maximum of 200 uV. The -E suffix identifies the electrical grade, while the /ST package designation corresponds to the 14-pin TSSOP package described for this device. Microchip mCal is an important architectural feature of the MCP62x family. At power-up, the amplifiers are self-calibrated to improve offset performance. This calibration makes the family useful where DC offset can influence measurement accuracy, transducer conditioning, or closed-loop control behavior. Designers should still account for output settling and startup time when sequencing sensitive analog systems. Typical uses include 2.5 V and 5.5 V precision signal conditioning, low-voltage sensor interfaces, active filters, instrumentation buffers, audio preamplifier stages, and four-channel acquisition front ends. The 20 MHz bandwidth provides useful speed for low-amplitude signals, while the 14 TSSOP outline supports conventional surface-mount assembly. PCB design should provide a solid return path, short feedback loops, and careful placement of input, output, and compensation-network components. Decoupling capacitors should be connected directly to the supply pins, and unused amplifier inputs must be biased so they do not float. The 5.5 V maximum operating supply also leaves no tolerance margin above that voltage. This product page combines the manufacturer specifications with practical considerations for decoupling, layout, calibration behavior, signal conditioning, and drop-in sourcing. It also highlights the electrical and package constraints that must be checked before replacing the MCP624-E/ST in an existing 14-pin TSSOP design.

MCP6242-E/P

MCP6242-E/P - Dual 550kHz Rail-to-Rail Op Amp | Microchip

The Microchip Technology MCP6242-E/P is a dual general-purpose operational amplifier featuring a 550 kHz gain-bandwidth product, rail-to-rail input and output, and operation from a single 1.8 V to 5.5 V supply. The device is packaged in an 8-pin PDIP and provides two independent amplifier channels for compact analog signal-conditioning designs. An operational amplifier, or op amp, is a high-gain differential amplifier used to amplify, buffer, filter, compare, or control analog signals. The MCP6242 belongs to the operational amplifier hierarchy of analog ICs and combines low supply current, wide bandwidth, and rail-to-rail signal handling in a low-power package suitable for portable, industrial, instrumentation, and control applications. The main electrical strengths include a typical 550 kHz gain-bandwidth product, 68-degree typical phase margin, 50 µA typical quiescent current, and rail-to-rail input and output operation. Its low operating voltage permits direct use in 1.8 V, 2.5 V, 3.3 V, and 5 V systems. Input common-mode rejection of at least 60 dB and typical input offset voltage of 5 mV support accurate amplification around the supply rails. The MCP6242 family is intended for general-purpose applications where moderate bandwidth and low quiescent current are more important than very high slew rate or very low offset voltage. Each amplifier can operate as an inverting or non-inverting gain stage, voltage follower, comparator, active-filter element, or transducer interface. Rail-to-rail input reduces the need for artificial biasing in single-supply sensing, while rail-to-rail output improves dynamic range when the required output swing approaches a supply rail. Typical uses include portable sensor interfaces, battery-powered measurement systems, industrial control modules, audio preamplifiers, and low-voltage data-acquisition circuits. The 8-pin PDIP package also facilitates prototyping and hand assembly. Designers should still account for input bias current, offset error, capacitive-load stability, output-current capability, and noise when defining the gain and feedback network. For a stable single-supply design, bypass the supply pins with local ceramic capacitance and keep feedback components close to the amplifier inputs and outputs. Avoid operating large capacitive loads directly at the output unless the output-stage stability limits are checked. This page combines manufacturer specifications, package details, application guidance, and pin-compatible family options for faster engineering selection. The MCP6242-E/P designation identifies the extended-temperature, PDIP-version member of the MCP6242 family. It is appropriate when a through-hole package is preferred for manual assembly, prototypes, repair, or applications where leaded mounting simplifies inspection. For production designs that prioritize PCB area, surface-mount variants should be reviewed separately, while the electrical design must remain compatible with the selected package variant.

An operational amplifier is an analog integrated circuit that uses high open-loop gain to amplify differences between input voltages. The MCP6244 belongs to the broader hierarchy of operational amplifier, analog amplifier, signal-conditioning IC, and semiconductor. Its rail-to-rail input and output characteristics allow signals to approach the supply rails, improving signal utilization in battery-powered and mixed-signal equipment operating from low supply voltages. The MCP6244 family provides 1.8 V minimum operation, a 550 kHz typical gain-bandwidth product for the family, and a typical phase margin of 68 degrees according to the Microchip product page. The MCP6244-E/P listing identifies the E/P configuration as an extended-temperature quad amplifier with 650 kHz bandwidth. Rail-to-rail inputs and outputs support acquisition and drive circuits where conventional input or output headroom would otherwise become the limiting factor. Four independent amplifiers can implement sensor conditioning, active filtering, differential measurement, level translation, and small-signal drive functions. The low-voltage supply range is particularly useful for portable instruments, industrial sensor interfaces, audio and communication equipment, and embedded control systems. A single 14-pin PDIP package also simplifies prototyping and repair because it can be socketed rather than surface-mounted. Designers should evaluate noise, input bias current, output drive, capacitive loading, and stability for the intended gain before finalizing the circuit. The listed phase margin provides a starting point for closed-loop analysis, but PCB leakage, source impedance, load capacitance, and the selected feedback topology can change dynamic performance. Decoupling should follow the manufacturer application guidance, with short return paths and local supply bypassing to reduce amplifier interaction. This page combines the manufacturer family information with package, temperature, interface, and application details, plus practical guidance for evaluating this quad amplifier in precision analog designs. It also identifies the differences that matter when considering a same-package replacement or planning a multi-amplifier signal-conditioning board.

Designed for low-voltage signal conditioning, the device operates from 1.8 V and is housed in a 10-DFN 3x3 mm surface-mount package. An operational amplifier is an analog signal-conditioning IC that uses high-gain feedback to amplify voltage differences. The MCP625-E/MF belongs to the operational-amplifier hierarchy within amplifier ICs and semiconductor electronics. Its dual-circuit configuration allows two independent amplifier channels in one package, reducing board area in portable, industrial, automotive, and test-and-measurement equipment. The principal performance features include a 20 MHz gain-bandwidth product, 10 V/µs slew rate, rail-to-rail inputs and outputs, and operation down to 1.8 V. The automotive-oriented E temperature grade supports extended-temperature operation. These characteristics make the amplifier suitable for sensor interfaces, current sensing, active filtering, audio signal paths, and general low-voltage analog systems. At a 20 MHz gain-bandwidth product, a closed-loop gain of 10 corresponds to an approximate bandwidth of 2 MHz before other practical limitations become significant. The 10 V/µs slew rate allows relatively fast transitions and reduces distortion when driving higher-capacitance loads. Rail-to-rail input capability improves usable input range near the supply rails, while rail-to-rail output operation increases output-voltage headroom. Typical uses include battery-powered sensor conditioning, industrial control signals, automotive interface circuits, instrumentation amplifiers, active filters, and low-voltage audio electronics. In a current-sensing application, the two channels can amplify a small differential voltage and buffer an unrelated reference or monitor signal, provided the common-mode and output ranges satisfy the electrical limits. Layout and stability remain important design considerations. Place the device close to the feedback network and sensitive input nodes, keep high-current return paths out of analog signal paths, and provide an exposed-pad thermal connection according to the manufacturer land pattern. Stable operation with capacitive loads may require an isolation resistor between the amplifier output and the load. This product page combines the manufacturer-device identity, distributor specifications, package information, technical application guidance, and replacement-selection context to support faster engineering decisions.

MCP6272-E/P

MCP6272-E/P - Dual 2MHz RRO Op Amp | Microchip

The Microchip Technology MCP6272-E/P is a dual-channel operational amplifier with a 2 MHz typical gain-bandwidth product, rail-to-rail input and output operation, and an 8-pin DIP package. It operates from a single supply up to 5.5 V, draws 170 µA typical supply current, and provides a minimum common-mode rejection ratio of 70 dB. The typical input offset voltage is 3 mV, and the extended-temperature version supports operation to +125 °C. These characteristics place the device in the general-purpose operational-amplifier category, where low power, moderate bandwidth, and input/output swing close to the supply rails are useful for portable and precision signal-conditioning systems. An operational amplifier, commonly abbreviated op amp, is an analog integrated circuit that amplifies the difference between two input voltages. A dual op amp contains two amplifier channels in one package, allowing simultaneous amplification or the construction of differential, filtering, comparator, and feedback circuits. The MCP6272 family combines a 2 MHz gain-bandwidth product with 65° phase margin and rail-to-rail input and output characteristics, making it suitable for general-purpose low-power signal conditioning. Key features include two amplifier channels, 2 MHz typical gain bandwidth, 170 µA typical supply current, and operation from a single supply to 5.5 V. The input offset voltage is 3 mV, while the common-mode rejection ratio is at least 70 dB. Rail-to-rail input and output behavior allows the amplifier to process signals near the low and high ends of its supply range. The extended-temperature capability reaches +125 °C, supporting applications with a wider environmental range than standard commercial-grade devices. The 2 MHz gain-bandwidth product defines the approximate frequency range available for useful closed-loop gain. For example, a 10-times voltage gain would place the amplifier near 200 kHz based on the 2 MHz gain-bandwidth product. The 65° phase margin provides stability-oriented design guidance for common feedback configurations. These figures make the MCP6272 practical for low-to-moderate-frequency instrumentation, sensor interfaces, audio preamplification, filtering, and general embedded analog signal paths rather than demanding high-speed video or RF amplification. Typical uses include battery-powered sensor conditioning, buffered ADC inputs, low-frequency active filters, audio input stages, and general dual-channel analog interfaces. The low 170 µA typical supply current is particularly useful in compact embedded systems where each additional milliamp can affect battery life. Two channels also reduce component count when a board needs paired amplification, differential buffering, or independent signal paths. Design should account for the 5.5 V maximum supply, input common-mode range, output swing, load capacitance, and stability requirements. Place the bypass capacitor close to the supply pins and route feedback components to minimize parasitic effects. Confirm the intended operating temperature and package constraints against the manufacturer datasheet before releasing a production PCB. This product page combines manufacturer specifications, package information, sourcing guidance, application fit, and engineering-focused design notes. It also distinguishes true same-package drop-in replacements from nearby family variants in other packages, helping designers avoid substitutions that require PCB or footprint changes.

The family’s 2 MHz gain-bandwidth product provides useful bandwidth for low-frequency precision and general-purpose analog signal paths. A 65-degree phase margin supports stable operation in common feedback configurations. The typical 170 uA quiescent current reduces the standing power requirement of battery-operated equipment, and the 2.0 V minimum single-supply operation makes the amplifier compatible with modern low-voltage rails. The MCP6273-E/P is specified in an 8-pin PDIP package for through-hole PCB assembly. This amplifier is intended for signal paths that need more bandwidth than a micropower comparator but do not require the drive or speed of a high-performance precision amplifier. Its rail-to-rail behavior is particularly valuable when the usable input range must cover much of the supply voltage. Designers should still evaluate output-current capability, noise, input bias current, common-mode limits, and stability under the intended loading before fixing a gain or output stage. Typical uses include low-frequency sensor conditioning, portable measurement systems, audio input stages, current-sense buffers, and general-purpose analog gain blocks. The MCP6273-E/P can also form the active element in filters and instrumentation amplifiers when component tolerances and operating bandwidth support the required accuracy. The 2.0 V operating supply and 170 uA typical quiescent current are particularly attractive for compact battery-powered products. The principal design consideration is stable feedback compensation. Keep the feedback network close to the amplifier, avoid excessive capacitive loading at the output, and confirm the selected gain against the 2 MHz gain-bandwidth product and 65-degree phase margin. The manufacturer datasheet should be used to assign the eight package pins, select input and output capacitors, and verify operating limits. This product page combines package information, searchable technical attributes, verified commercial availability, replacement guidance, and practical analog-design notes in one searchable reference. It helps engineers distinguish the MCP6273-E/P from related package and amplifier options before committing a PCB footprint or low-voltage power budget.

It operates from a 2.4 V to 6.0 V single supply and is intended for low-power applications requiring four amplifiers in one package. An operational amplifier, or op amp, is a high-gain analog building block used to amplify, buffer, filter, compare, and drive signals. The MCP6294 belongs to the operational-amplifier hierarchy, where it combines low-noise voltage amplification with a wide common-mode input range. Rail-to-rail input and output operation allows signals to approach the supply limits, which is useful in low-voltage sensor, signal-conditioning, and mixed-signal systems. The principal features are 10 MHz typical gain-bandwidth product, 65° phase margin, 8.7 nV/√Hz input noise, and 50 mA output-current capability. The MCP6294-E/P consumes 1.0 mA typical quiescent current per amplifier and operates over an extended temperature range of -40°C to +125°C. These characteristics balance bandwidth, noise, supply voltage, and power consumption rather than maximizing any single parameter. Each of the four amplifiers includes rail-to-rail input and output stages. The common-mode input range extends beyond the conventional input stages, improving signal capture when the input approaches either supply rail. The 10 MHz gain-bandwidth product supports moderate-frequency signal paths, while the 65° phase margin provides stability margin for common closed-loop gain configurations. Typical input offset voltage is 3 mV, and minimum common-mode rejection ratio is 70 dB. Typical uses include low-voltage sensor conditioning, current-loop and voltage-loop amplification, analog filtering, ADC input buffering, general-purpose instrumentation, and mixed-signal control. Combining four amplifiers in one package can also reduce board area and simplify power distribution where four matching amplifier channels are required. Designers should check input and output swing, capacitive-load stability, noise gain, and system grounding. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs should be biased to a valid common-mode level. The extended-temperature grade is suited to industrial environments when the board, solder, and surrounding components also meet the required temperature limits. This page combines the manufacturer specifications with package-level guidance, application fit, and practical design considerations. It also distinguishes verified device characteristics from parameters that still require circuit-level confirmation, helping engineers evaluate the MCP6294-E/P before PCB implementation.

The Microchip Technology MCP652-E/SN is a dual operational amplifier with a typical gain-bandwidth product of 50 MHz, rail-to-rail output, 30 V/us slew rate, and low 7.5 nV/Hz input-noise density. It is packaged as an 8-pin SOIC and specified for operation from -40C to +125C. The MCP652-E/SN also uses Microchip's mCal self-calibration technology to reduce input-offset voltage during power-up. An operational amplifier, or op amp, is a high-gain analog building block used to amplify small signals, buffer sensors, compare voltages, and drive analog-to-digital converters. The MCP652-E/SN belongs to the MCP65x family of low-offset, high-speed, low-noise amplifiers. It combines single-supply operation, rail-to-rail output, low distortion, and self-calibration in an 8-pin SOIC footprint suitable for general-purpose analog signal chains. Key electrical characteristics include a 50 MHz typical gain-bandwidth product, 30 V/us typical slew rate, 81 dB typical common-mode rejection, and a calibrated input-offset-voltage limit of +/-200 uV.

The dual configuration provides two amplifiers in one package, reducing board area in filtering, buffering, and differential signal-conditioning circuits. The MCP65x architecture performs self-calibration at power-up to lower input-offset voltage. This calibration is valuable in precision applications because input offset can otherwise create DC error, shift comparator thresholds, or reduce the effective resolution of an ADC. The rail-to-rail output allows the amplifier to approach the supply limits when higher output swing or wider signal range is required, although input-common-mode limits must still be checked for each operating condition. Typical uses include sensor signal conditioning, active filters, audio and communication paths, ADC drivers, comparators, and low-voltage instrumentation. The dual configuration is especially useful when a design needs two gain stages, a filter followed by an ADC driver, or an instrumentation amplifier built from matched amplifiers. The -40C to +125C temperature range supports industrial environments, while the standard 8-pin SOIC package simplifies assembly and board-level sourcing. The principal design trade-off is operating speed versus power and stability. High gain-bandwidth and slew rate support faster signal transitions, but feedback networks, capacitive loads, decoupling, and output-current limits still require careful review. Place bypass capacitors near the supply pins, keep feedback loops compact, and verify stability with the actual source and load impedances before releasing the layout.

A single package containing three channels also reduces board area and simplifies multi-axis, multi-channel, or multi-filter designs. Architecturally the part is a CMOS operational amplifier with a high gain-bandwidth product and rail-to-rail output stage, intended for general-purpose signal conditioning rather than precision DC measurement. The 32 V/us slew rate and 60 MHz bandwidth make it suitable for active filters, audio preamplification, sensor buffering, and instrumentation where the signal bandwidth exceeds that of typical micropower amplifiers, while the low minimum supply voltage of 2.5 V allows direct operation from single-cell and 3.3 V rails. Typical applications include active low-pass and band-pass filters for sensor conditioning, audio and microphone preamplifier stages, buffer stages ahead of ADCs, communications and line-driver receive paths, and general instrumentation front ends where multiple channels must be matched for common-mode and bandwidth behaviour. The triple configuration is especially useful when three axes of a measurement or three filters of a signal chain must share supply and layout characteristics. When designing with the MCP660-E/ST, pay attention to stability when driving capacitive loads: place output decoupling close to the supply pins, keep feedback networks compact, and confirm gain stability with the actual load. Because the amplifier is rail-to-rail at the output, the input common-mode range versus output swing should be checked against the datasheet curve for the specific supply voltage. The extended temperature grade also demands attention to DC bias drift when the amplifier is used as a precision DC buffer. This page consolidates channel count, bandwidth, slew rate, supply range, package and temperature-class information for the MCP660-E/ST, adds pin-level detail, package-and-footprint-compatible alternatives, parameter-by-parameter comparison, and practical design notes that are not presented together on a manufacturer datasheet landing page.

MCP662-E/SN - Dual 60MHz Rail-to-Rail Op Amp | Microchip

The Microchip Technology MCP662-E/SN is a dual operational amplifier with a 60 MHz typical gain-bandwidth product, 32 V/us typical slew rate, and rail-to-rail output in an 8-pin SOIC package. Designed for low-voltage signal processing, it operates from 2.5 V to 5.5 V and supports an extended temperature range from -40 C to 125 C. An operational amplifier is a voltage-controlled differential amplifier that uses feedback to amplify the difference between two input signals. The MCP662 belongs to the CMOS operational-amplifier hierarchy within analog and mixed-signal semiconductors. Its combination of high bandwidth, high output short-circuit current, and low-noise performance makes it suitable for filtering, buffering, sensor conditioning, audio signal paths, and communications equipment operating from a single low-voltage supply. Key electrical features include a 79 dB typical common-mode rejection ratio, 6.8 nV/Hz typical input-voltage noise at 1 MHz, and a 90 mA typical output short-circuit current. The two-amplifier configuration allows one package to support simultaneous signal paths. Rail-to-rail output capability improves dynamic range when signals approach the positive or negative supply limits, while the 2.5 V minimum supply supports portable and embedded systems powered from regulated 3.3 V or lower rails. The MCP66x family is optimized for high-speed operation. Its 60 MHz gain-bandwidth product allows operation at moderate closed-loop gains, and the 32 V/us slew rate supports rapid transitions in filtering, waveform generation, and data-conversion interface circuits. The 90 mA typical short-circuit current provides drive capability for capacitive loads and higher-impedance downstream stages, although external isolation may still be required for large capacitive loads. Typical uses include low-voltage audio signal conditioning, ADC and DAC input or output buffering, active filters, portable instrumentation, industrial sensor interfaces, and communications equipment. The dual configuration can implement two independent amplifier channels or a differential signal-conditioning stage when the circuit requirements match. Designers should verify stable operating-gain configurations, output-capacitance limits, input-bias behavior, and noise performance using the manufacturer datasheet. Place bypass capacitance close to the supply pins, provide adequate output-current margin, and use resistive isolation when driving large capacitive loads or long PCB traces. This page combines the MCP662-E/SN electrical characteristics with same-package alternatives, application guidance, comparison parameters, and practical PCB design notes. It is intended to help engineers confirm footprint compatibility, speed, noise, supply range, and thermal requirements before integrating the amplifier into a new analog signal chain.
