MCP6283-E/P - 5MHz Dual RRIO Op Amp | Microchip
MPN: MCP6283-E/P ✓ Hoạt độngMCP6283-E/P Tóm tắt
An operational amplifier is a voltage-gain and signal-conditioning semiconductor used in analog, mixed-signal, and power-control systems. Common functions include buffering, amplification, active filtering, current-to-voltage conversion, differential sensing, and feedback control. Rail-to-rail input and output, commonly abbreviated RRIO, extends the usable input and output range toward the supply rails. The MCP6283-E/P belongs to Microchip's MCP6281, MCP6281R, MCP6282, MCP6283, MCP6284, and MCP6285 family of low-power operational amplifiers.
The MCP6283-E/P provides a typical gain-bandwidth product of 5 MHz and a 65° phase margin. Its typical slew rate is 2.5 V/µs, while the typical supply current is 450 µA per amplifier. The device also specifies 85 dB common-mode rejection and 0.0050 µA typical input bias current. These characteristics make it suitable for low-power sensor conditioning, current measurement, filtering, buffering, and portable-equipment signal paths where amplifier current consumption is important.
The single-supply architecture simplifies power planning in battery-operated and embedded systems. Rail-to-rail inputs are particularly useful when sensor outputs approach ground, while rail-to-rail outputs improve output swing for low-voltage analog signals. Designers should nevertheless account for input and output common-mode limits, output-current capability, capacitive-load stability, and the voltage drop across the power pins when establishing system operating limits.
Typical uses include portable medical instruments, industrial sensor interfaces, battery-powered monitoring equipment, low-voltage data acquisition, active analog filters, and audio input conditioning. The extended temperature range allows use in industrial environments where the ambient or enclosure temperature can reach 125°C, provided the board layout maintains the intended operating conditions.
For PCB implementation, place the SOT-23-6 close to the signal source and receiver, route the ground return directly to the device ground pin, and decouple the supply with a local bypass capacitor. Check the recommended capacitor type and value in the manufacturer datasheet for the intended gain, noise, and stability requirements. This page consolidates the device specifications, sourcing workflow, application guidance, and replacement considerations into one engineering-focused reference.

Ứng dụng tiêu biểu
MCP6283-E/P phù hợp cho 6 Áp dụngs: Portable Sensor Conditioning, Battery-Powered Monitoring, Current-Sense Amplification, Active Analog Filtering, Industrial Data Acquisition, Low-Voltage Audio Input Buffer.
Portable Sensor Conditioning
The MCP6283-E/P fits low-power sensor interfaces because its rail-to-rail input stage can accommodate signals near ground while its 5 MHz gain-bandwidth product supports reasonably fast analog signals. The 450 µA typical supply current is valuable in battery-operated equipment where every amplifier microamp affects operating life. Use the device as a non-inverting or inverting buffer ahead of an ADC, and confirm that the sensor's source impedance does not degrade offset or noise performance. The -40°C to +125°C rating also supports compact industrial sensing products exposed to temperature variation.

Battery-Powered Monitoring
For battery-powered monitors, the MCP6283-E/P combines a 450 µA typical supply current with rail-to-rail input and output behavior in a compact SOT-23-6 package. It can amplify a transducer output toward the usable range of a low-voltage ADC without requiring a mid-supply bias when the source signal remains near ground. The 5 MHz gain-bandwidth product allows closed-loop bandwidth beyond slow monitoring signals, although actual noise gain and output settling must be checked. Using the minimum practical gain also helps control power consumption.
Được đề xuất
Current-Sense Amplification
The MCP6283-E/P is suitable for amplifying the small differential voltage produced by a shunt resistor in current-measurement systems. Its 85 dB common-mode rejection helps reject common-mode noise when the shunt voltage is superimposed on a larger supply-derived voltage. The 2.5 V/µs typical slew rate provides useful response margin for moderately fast current transients. Choose the closed-loop gain carefully because noise gain affects both bandwidth and output swing, and verify that common-mode and output limits remain valid at the highest expected current.
Được đề xuất
Active Analog Filtering
The MCP6283-E/P can implement active low-pass, high-pass, or band-pass sections where a compact 5 MHz operational amplifier is needed. Its 5 MHz typical gain-bandwidth product and 65° phase margin are the principal parameters for selecting closed-loop gain and filter impedance. Lower resistance values can increase bandwidth but also increase noise and may alter loading, while high impedance values reduce current consumption yet amplify offset and leakage effects. Validate stability, component tolerances, and stop-band attenuation with the intended operating frequency and load.
Được đề xuất
Industrial Data Acquisition
The MCP6283-E/P fits compact industrial data-acquisition front ends that require two analog channels, rail-to-rail signal handling, and extended-temperature operation. Its dual-channel configuration can reduce board area when conditioning two related inputs, while the 6-pin SOT-23 package simplifies high-density assembly. The -40°C to +125°C operating range is useful in equipment deployed near heat sources or in industrial enclosures. Designers should still evaluate long-term temperature drift, precision limits, noise, and the common-mode range at the actual signal levels.
Được đề xuất
Low-Voltage Audio Input Buffer
The MCP6283-E/P can serve as a low-level audio input buffer in portable equipment when the source impedance and required bandwidth match the amplifier's characteristics. The 5 MHz gain-bandwidth product is substantially above the bandwidth of many audio paths, while the 2.5 V/µs typical slew rate supports non-critical audio signals. Rail-to-rail output operation improves swing on a low supply, though output distortion and load drive must be checked at the selected frequency. Input and output coupling capacitors also require suitable bias-current and DC-offset analysis.

Ghi chú thiết kế
Place the MCP6283-E/P close to the signal source, the ADC, or the feedback network it serves. Connect its ground pin to the quiet analog ground using a short, low-impedance path, and position the supply bypass capacitor directly between the supply and ground pins. Keep the amplifier input nodes away from switching-node copper and high-current return paths. Correct package orientation and pin assignment must follow the manufacturer datasheet.
Do not assume that rail-to-rail input and output operation guarantees full output swing at every load. Check output-current limits, output-voltage headroom, input common-mode behavior, and capacitive-load stability under the worst-case supply voltage. Also account for input-offset voltage and input-bias-current error when high source impedance makes those parameters significant. These checks are particularly important when operating from a low 5 V nominal supply.
Choose closed-loop gain and feedback components using the 5 MHz typical gain-bandwidth product and 65° phase margin rather than bandwidth alone. Lower feedback resistance can support higher bandwidth but increases noise and output-current demand, while very high resistance can increase offset and leakage sensitivity. Confirm settling behavior, feedback-node capacitance, grounding, and output loading with the intended signal bandwidth before finalizing the amplifier configuration.
The MCP6283-E/P is rated for -40°C to +125°C, but package temperature and system reliability still depend on copper area, airflow, nearby heat sources, and dissipation. Treat the extended-temperature rating as an operating capability rather than a substitute for thermal analysis. In sealed industrial equipment, verify the temperature rise inside the enclosure and avoid placing the amplifier next to regulators or power devices without an adequate thermal path.
