MCP616-I/MS - 190kHz Micropower Op Amp | Microchip
MPN： MCP616-I/MS ✓ 啟用中MCP616-I/MS 概覽
An operational amplifier, or op amp, is a voltage-feedback analog amplifier that provides high open-loop gain and is commonly configured with external components for amplification, filtering, buffering, comparison, and signal-conditioning functions. The op amp belongs to the linear amplifier hierarchy and ultimately supports analog signal-chain, instrumentation, industrial-control, and embedded-system designs.
The MCP616 combines low power consumption with rail-to-rail output swing. Its 190 kHz gain-bandwidth product supports signal processing at relatively low frequencies, while the typical 19 uA operating current is suitable for battery-operated and loop-powered equipment. The offset voltage below 150 uV helps minimize input-stage imbalance, and Microchip's advanced CMOS process provides low bias current, high open-loop gain, and high-speed operation.
The MCP616 uses a Bi-CMOS architecture and accepts a 2.3 V to 5.5 V supply. Its general-purpose design makes it suitable for portable measurements, low-end audio, industrial process control, data acquisition, test equipment, and sensors. The single-amplifier configuration minimizes board area where only one analog channel is required, although multi-channel systems may benefit from a dual or quad amplifier.
The -I suffix identifies the industrial temperature grade, while the /MS package code denotes the MSOP package variant. Surface-mount construction simplifies automated assembly but requires careful control of exposed-pad or lead soldering, copper thermal relief, and analog-signal routing. Review the manufacturer's pin-description and ordering tables before assigning PCB nets.
When designing around the MCP616-I/MS, verify the required input and output common-mode range for the selected gain configuration. Keep feedback-loop routing compact, provide stable bypass capacitance near the supply pins, and avoid placing high-current digital paths beneath sensitive analog inputs. The 190 kHz bandwidth makes it more appropriate for slow sensor and instrumentation signals than for wideband communications or video.
This product page combines manufacturer specifications, package details, practical application guidance, and same-family drop-in comparisons. It is designed to help engineers evaluate the MCP616-I/MS against alternative amplifiers while keeping the decisions tied to supply voltage, current consumption, gain-bandwidth product, offset voltage, and package compatibility.

典型應用
MCP616-I/MS 適用於 6 應用s: Battery-Powered Sensor Conditioning, Portable Data Acquisition, Industrial Process Control, Low-End Audio Signal Path, Portable Test and Measurement, Loop-Powered Instrumentation.
Battery-Powered Sensor Conditioning
The MCP616-I/MS fits battery-powered sensor interfaces because it operates from 2.3 V to 5.5 V and consumes only 19 uA typical operating current. Its 190 kHz gain-bandwidth product is ample for common temperature, pressure, humidity, and level sensors that produce slowly changing analog voltages. The amplifier can provide gain or buffering ahead of an ADC while limiting battery drain. The 190 kHz bandwidth also leaves sufficient loop bandwidth for modest compensation networks, although capacitor selection and sensor-source impedance must be evaluated to prevent instability. Because the output is rail-to-rail, the circuit can use more of a low supply range, but input common-mode limits remain a separate design consideration near the rails.
推薦
Portable Data Acquisition
The MCP616-I/MS is appropriate for portable data-acquisition front ends requiring modest bandwidth and low operating current. A 190 kHz gain-bandwidth product can amplify sensor, transducer, and diagnostic signals without introducing the power cost of a high-speed amplifier, while offset voltage below 150 uV supports low-level measurements. Use the amplifier in a non-inverting or differential conditioning stage and select the external resistor values for the required closed-loop gain. Pay attention to source impedance because high source resistance combined with input capacitance can reduce phase margin. The 8-MSOP package supports compact instrument boards while retaining gull-wing leads that are inspectable after assembly.
推薦
Industrial Process Control
The MCP616-I/MS suits industrial process-control modules that monitor slow pressure, temperature, or valve-position signals. Its 19 uA typical operating current minimizes auxiliary power demand, while the industrial-temperature grade supports use across a wider ambient range than a consumer-grade amplifier. The device can buffer a transmitter output, amplify a scaled sensor signal, or form an active filter ahead of an ADC. Keep the feedback loop short on the PCB and avoid routing it alongside motor-control or relay-switching nodes. Because the gain-bandwidth product is 190 kHz, exceptionally fast loops, wideband isolation amplifiers, and video signals are better served by higher-bandwidth devices.
推薦
Low-End Audio Signal Path
The MCP616-I/MS can be used in low-end audio and microphone preamplifier circuits where low power and low cost are more important than wideband audio performance. The 190 kHz gain-bandwidth product provides substantially more bandwidth than typical human-audio frequencies, and the rail-to-rail output swing can improve utilization of a 2.5 V or 3.3 V supply. Input bias current and noise are important in microphone applications, so the manufacturer characteristic limits should be checked against the transducer source impedance. Add input filtering as required for RF immunity, keep the feedback components close to the device, and verify output headroom for the intended signal amplitude.
推薦
Portable Test and Measurement
The MCP616-I/MS is well matched to handheld meters and compact test instruments that need accurate low-level signal conditioning with low battery consumption. Its offset voltage below 150 uV is helpful when amplifying small transducer outputs, and the 190 kHz gain-bandwidth product supports meter-band and general-purpose diagnostic signals rather than high-speed waveform capture. The single amplifier in an 8-MSOP package leaves board area for measurement circuitry, power management, and an interface controller. Layout should isolate the analog input from display, switching, and reference-node drive paths. Stable feedback compensation and adequately decoupled supply rails are essential when a precision measurement is performed at low supply voltages.
推薦
Loop-Powered Instrumentation
The MCP616-I/MS is appropriate for loop-powered instrumentation because its 2.3 V minimum supply and 19 uA typical operating current support operation from constrained power budgets. The amplifier can buffer a sensor or transmitter at the input of a current-loop interface while the 190 kHz bandwidth comfortably covers conventional process-control bandwidth. The 8-MSOP package is useful in compact field transmitters. Nevertheless, the complete loop still needs adequate compliance voltage and current budget, and protection against polarity reversal or surge must be designed separately. Review the amplifier's input and output ranges at the lowest loop voltage to ensure the signal remains valid throughout startup and load changes.

主要差異化特點
- Lower operating current supports battery and loop-powered designs (對比MCP619-I/MS)
- A 190 kHz response is optimized for slow precision signals rather than high-speed waveforms (對比MCP619-I/MS)
- Low offset voltage supports low-level measurement (對比MCP618-I/MS)
設計說明
Place the input, output, feedback, and compensation components close to the MCP616-I/MS pins to minimize parasitic capacitance and feedback-loop area. Keep sensitive input traces away from switching-regulator outputs, relay contacts, high-current LED drivers, and digital clock lines. A solid ground plane and short ground-return paths help preserve accuracy when the amplifier is used with a high-impedance sensor.
Use local supply bypass capacitance close to the amplifier and follow the manufacturer recommendations for capacitor type, voltage rating, and effective capacitance across temperature. The MCP616-I/MS accepts a 2.3 V to 5.5 V supply, but its usable input and output range is narrower than the full supply in some operating conditions. Verify common-mode limits, output swing, and load current at the minimum system voltage before finalizing the power architecture.
Do not assume that rail-to-rail output means the input can also swing rail to rail. Review the MCP616 input common-mode range and the effects of output saturation on the feedback loop. Likewise, check stability with the actual sensor capacitance, cable length, and gain-setting resistors. A nominal 190 kHz gain-bandwidth product does not guarantee stability for every externally compensated configuration.
