MCP6293-E/P - 10MHz Low-Power R-R Op Amp | Microchip
MPN: MCP6293-E/P ✓ NakahandaMCP6293-E/P Ulas
An operational amplifier, or op amp, is an analog amplifier that uses very high open-loop gain to amplify the difference between two input voltages. The rail-to-rail input and output architecture allows the MCP6293-E/P to operate close to the positive and negative supply rails, making it useful in portable instrumentation, sensor signal conditioning, audio, and low-voltage control systems where the available signal range is limited.
The family’s 10 MHz gain-bandwidth product provides useful bandwidth for moderate-frequency signal paths. A 65° phase margin supports stable operation in common closed-loop amplifier configurations. The 1 mA typical quiescent current reduces the supply burden in battery-operated and compact embedded equipment, while the 2.4 V minimum single-supply operation supports compatibility with low-voltage systems.
The MCP6293-E/P uses rail-to-rail inputs and outputs, allowing input and output voltages to approach the supply limits without requiring a separate negative supply. This characteristic is particularly valuable in low-voltage sensor interfaces, where the sensed signal can occupy much of the available input range. Its single-channel configuration also simplifies PCB routing when each signal requires independent gain or buffering.
Typical uses include portable sensor conditioning, low-voltage audio stages, active filtering, transducer amplification, and general-purpose analog buffering. The 8-pin PDIP package remains convenient for through-hole prototypes, educational designs, laboratory assemblies, and systems assembled from leaded components rather than compact surface-mount production.
Designers should verify the complete electrical limits, unity-gain stability configuration, input bias behavior, output-swing limits, and recommended external compensation values in the Microchip MCP6291 family data sheet. PCB layout should keep input, feedback, and ground connections short to minimize parasitic capacitance and maintain the intended bandwidth and stability.
This page combines package-specific identification, application guidance, practical design notes, and a parameter-focused replacement analysis to support faster component selection and PCB design for the MCP6293-E/P.

Tipikal na mga Gamit
MCP6293-E/P ay nararapat para sa 6 aplikasyons: Low-Voltage Sensor Signal Conditioning, Portable Audio Preamplification, Active Filtering and Equalization, Industrial Control Signal Conditioning, Battery-Powered Data Acquisition, Test and Measurement Buffering.
Low-Voltage Sensor Signal Conditioning
The MCP6293-E/P fits sensor interfaces because its rail-to-rail inputs accept signals extending toward the supply limits while its 10 MHz gain-bandwidth product handles moderate-frequency sensor waveforms. The 2.4 V minimum operating supply supports compact 3.3 V systems, and 1.0 mA typical quiescent current limits power use in battery-powered sensing equipment. Engineers can use the amplifier for gain, active filtering, or buffering around resistive dividers, thermistors, and low-current transducers. Before finalizing the gain and bias network, check the exact input common-mode range, output swing, and noise behavior in the Microchip MCP6291 family data sheet.
Inirekomenda
Portable Audio Preamplification
The MCP6293-E/P can provide input buffering or modest gain in low-voltage audio paths because its 10 MHz gain-bandwidth product comfortably exceeds the bandwidth of many microphone and line-level stages, while rail-to-rail inputs and outputs increase usable signal range. A 2.4 V single supply and 1.0 mA typical quiescent current suit compact headphones, portable instruments, and battery-powered audio products. The through-hole PDIP package also simplifies prototype construction. Verify output swing into the intended load, capacitive-drive conditions, and the required closed-loop gain before using the device as a microphone preamplifier.
Inirekomenda
Active Filtering and Equalization
The MCP6293-E/P is appropriate for first-order and moderate-order active filters that need more bandwidth than a micropower rail-to-rail amplifier can provide. Its 10 MHz gain-bandwidth product and 65° phase margin provide a useful basis for designing low-frequency smoothing, anti-alias, and equalization networks, while rail-to-rail operation allows the signal to use much of a low-voltage supply range. Component tolerances and the op amp's finite gain and output behavior determine the realized filter response, so simulation and bench verification remain important.
Inirekomenda
Industrial Control Signal Conditioning
The extended -40°C to +125°C operating range of MCP6293-E/P makes it appropriate for industrial control boards where the signal interface may experience a wide ambient temperature range. Its 1.0 mA typical quiescent current is useful in distributed sensing and control nodes, and the 10 MHz gain-bandwidth product supports faster control or diagnostic signals than the family’s slowest operating regimes. The 8-pin PDIP format simplifies maintenance and through-hole prototypes. Engineers should still evaluate the complete power budget, noise performance, electromagnetic coupling, and long-term reliability of the associated passive components.
Inirekomenda
Battery-Powered Data Acquisition
The MCP6293-E/P can support multiplexed or distributed data-acquisition channels where low supply current and a compact signal path are important. Its 1.0 mA typical quiescent current complements a 2.4 V minimum supply, enabling operation from small energy-harvesting or regulated sources. Rail-to-rail inputs help preserve small sensor signals, while the 10 MHz gain-bandwidth product handles sampling and settling requirements above very low frequencies. The designer should calculate acquisition time, dynamic range, settling error, and total channel power consumption, and should add anti-alias filtering ahead of any converter.
Inirekomenda
Test and Measurement Buffering
The MCP6293-E/P can buffer probes, divider networks, and low-current sensor outputs in compact test and measurement equipment. Rail-to-rail input and output operation preserves signal span in low-voltage systems, while the 10 MHz gain-bandwidth product supports higher-bandwidth instrumentation than a unity-gain-stability-focused part would. The single-amplifier 8-pin PDIP package makes it convenient for laboratory cards and prototype boards. For precision measurement, verify offset, bias current, noise, settling, and input-capacitance behavior in the manufacturer data sheet rather than treating general-purpose op-amp ratings as metrology-grade guarantees.

Talaan ng Disenyo
Place the MCP6293-E/P close to its feedback resistors, input source, and supply bypass capacitors. Keep the inverting-input node compact because parasitic capacitance at that node can alter feedback behavior and stability. Route the non-inverting input away from switching nodes and the positive supply trace. For a PDIP implementation, preserve the manufacturer's recommended lead spacing and avoid long copper runs that behave as antenna-like signal couplings.
Decouple the positive supply close to pin 7 and connect the negative supply at pin 4 with a short return path. Select bypass capacitors according to the application circuit and frequency range; the manufacturer data sheet provides the recommended decoupling and stability information. Because the amplifier's typical quiescent current is 1.0 mA, include op-amp current when sizing the supply and assess startup behavior across the full 2.4 V to 6.0 V operating range.
Do not treat the 10 MHz gain-bandwidth product as the usable closed-loop bandwidth for every gain and load. Closed-loop response depends on noise gain, feedback impedance, load capacitance, and output-drive conditions. Confirm unity-gain stability, maximum capacitive load, input common-mode limits, and output swing in the Microchip MCP6291 family data sheet before finalizing the feedback network and load configuration.
