MCP6244-E/P - Quad 1.8V 650kHz Op Amp | Microchip
MPN: MCP6244-E/P ✓ ActiveMCP6244-E/P Overview
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.

Typical Applications
MCP6244-E/P is suitable for 6 applications: Low-Voltage Sensor Signal Conditioning, Portable Instrumentation Signal Conditioning, Active Audio and Communication Filtering, Industrial Sensor Interface, Power-Sequenced Control and Signal Interface, Precision Bridge and Differential Measurement.
Low-Voltage Sensor Signal Conditioning
The MCP6244-E/P fits sensor-conditioning circuits that operate from 1.8 V supplies because the family supports single-supply operation with rail-to-rail inputs and outputs. Four independent amplifiers can buffer a sensor, amplify the differential signal, and provide additional gain or active filtering stages. The listed 650 kHz bandwidth is suitable for many moderate-bandwidth measurements rather than high-frequency sensing. Before committing the design, verify offset voltage, input bias current, output drive, and noise against the sensor impedance and required accuracy. A high-impedance source may make input bias current more influential than bandwidth.
Recommended
Portable Instrumentation Signal Conditioning
The MCP6244-E/P supports compact, battery-operated instruments because the amplifier family operates from supplies as low as 1.8 V and includes rail-to-rail input and output stages. The four-channel arrangement allows one board to condition several low-level channels without using four separate packages. Rail-to-rail operation also improves usable signal range in systems where the measured voltage can approach either supply rail. Design the input network and feedback values against the required noise and accuracy, and confirm settling behavior for the selected closed-loop gain. The 650 kHz listed bandwidth provides margin for low-frequency measurement chains.
Recommended
Active Audio and Communication Filtering
The MCP6244-E/P can implement active filters, gain stages, and buffer sections in low-voltage audio or communication equipment. Its four amplifiers provide independent channels for a second-order filter and adjacent conditioning functions, while the 650 kHz listed bandwidth covers signal paths well below the megahertz range. Use the family phase margin of 68 degrees as an initial closed-loop stability reference, then verify the final network because source resistance, load capacitance, and parasitic capacitance can alter the response. Place each amplifier close to its decoupling capacitor and route high-impedance input nodes away from switching signals.
Recommended
Industrial Sensor Interface
MCP6244-E/P is appropriate for industrial interfaces that need a common low-voltage amplifier across several transducers or control signals. Its -40°C to +125°C operating range covers extended-temperature equipment, while the PDIP package supports socketed prototypes, maintenance assemblies, and through-hole production processes. Four channels can handle buffer, gain, difference, and filtering functions. The engineer should still check input common-mode range, output-current capability, electrical-noise behavior, and stability with the actual sensor and wiring. Long cable connections require attention to ground offsets and electrostatic-noise coupling.
Recommended
Power-Sequenced Control and Signal Interface
The four amplifiers in MCP6244-E/P can provide independent interface functions in an embedded control board, such as conditioning control outputs, buffering sensor lines, amplifying diagnostics, and driving an external analog block. Operation from a 1.8 V supply supports systems in which the analog section must share a low-voltage rail. Use separate local bypass paths for the four amplifiers where practical, because shared long supply traces can couple transient current between channels. Check output drive before driving an ADC input, reference, relay-control network, or cable, and use suitable protection when exposed to industrial wiring.
Recommended
Precision Bridge and Differential Measurement
The MCP6244-E/P is suitable for low-voltage differential measurement when paired channels are assigned to a bridge or other balanced sensor. Rail-to-rail input behavior improves compatibility with sensors operating near the supply limits, while the four-channel package can combine differential amplification with reference buffering and output filtering. The system must remain within the amplifier input common-mode range for every bridge excitation and temperature condition. Input bias current can create error across high source impedances, so calculate its contribution and confirm offset stability against the measurement accuracy. Resistor matching also directly affects differential rejection.

Key Differentiators
- Combines four amplifiers in one extended-temperature PDIP package (vs MCP6004-E/P)
- Supports low-voltage single-supply operation (vs MCP6004-E/P)
- Uses through-hole packaging for prototype and serviceability needs (vs MCP6244-E/SL)
Design Notes
Place the supply bypass capacitor close to the MCP6244 power pins and provide a low-impedance return path to the device ground. Because four amplifiers can be active simultaneously, size the local supply network for the aggregate transient demand of the intended channels rather than one amplifier alone. Keep analog and digital return currents separated where the board contains switching circuitry, and avoid sharing a long, narrow ground route between sensitive input and output channels.
Keep input and feedback traces short, and route them away from clocks, switching-regulator nodes, relay contacts, and other high-impedance sources. Connect the thermal and exposed conditions of the target board to the package requirements, using adequate copper and airflow where necessary. For high-impedance sensor inputs, use guarding, clean connectors, and short leakage-sensitive traces. The rail-to-rail characteristics do not eliminate input-bias-current error or the effect of surface contamination.
Do not substitute the 14-pin SOIC MCP6244-E/SL for the PDIP MCP6244-E/P without redesigning the PCB footprint. Also do not assume MCP6004-E/P is electrically equivalent solely because both are quad amplifiers in a PDIP package. Compare offset voltage, input bias current, noise, bandwidth, slew rate, output drive, and stability for the actual feedback network. Confirm the operating region, load capacitance, and maximum output current against the manufacturer documentation for the exact replacement.
