MCP616-I/P - 190 kHz Micropower Op Amp | Microchip
N.º de pieza: MCP616-I/P ✓ ActivoMCP616-I/P Descripción general
An operational amplifier, or op amp, is a high-gain analog building block used to amplify, buffer, filter, compare, and control voltage signals. The MCP616 belongs to the operational-amplifier hierarchy, where it functions as a voltage-feedback amplifier built with Microchip's advanced CMOS technology. Its low operating current and low-offset design make it suitable for portable, battery-powered, sensor-interface, and low-power signal-conditioning equipment.
The MCP616-I/P combines a 190 kHz gain-bandwidth product with a typical operating current of only 19 µA. Its offset voltage is less than 150 µV, while the rail-to-rail output allows the output to approach the supply rails more closely than a conventional non-rail-to-rail output stage. Microchip describes the device as a micropower Bi-CMOS operational amplifier with low bias current, high open-loop gain, and rail-to-rail output swing.
The single-supply operating range extends from 2.3 V to 5.5 V, allowing operation from a single lithium-cell source or a low-voltage regulated rail. The verified distributor data identifies one amplifier circuit per package and places the MCP616-I/P in an 8-pin PDIP package. Suitable bypass capacitance, clean grounding, and attention to output-load drive are important because low-power operational amplifiers may have limited load capability compared with higher-current amplifiers.
Typical uses include battery-powered sensor conditioning, portable instrumentation, biomedical monitoring, general signal buffering, low-frequency active filters, and threshold detection. In these applications, the MCP616-I/P provides useful bandwidth for slow-moving signals while consuming little operating current. The rail-to-rail output can improve dynamic range when the signal must be measured near the upper or lower end of the available supply range.
For PCB design, place the bypass capacitor close to the supply pins and route the non-inverting input to minimize leakage from nearby switching nodes. Avoid long traces that place the offset-voltage and bias-current contribution above the signal source's error budget. Because the available verified data does not specify the exact output-current limit, input common-mode range, or open-loop-gain curve, those values should be confirmed in the manufacturer datasheet before finalizing a high-precision design.
This page consolidates the verified manufacturer specifications, distributor availability, package information, pricing indication, and application guidance for the MCP616-I/P. It also separates directly relevant engineering facts from unverified parameters and identifies same-family alternatives for engineers who must verify pin compatibility and performance before substitution.

Aplicaciones típicas
MCP616-I/P es adecuado para 6 aplicacións: Battery-Powered Sensor Conditioning, Portable Medical Monitoring, Low-Frequency Active Filters, Industrial Threshold Detection, Portable Instrumentation Buffering, Low-Power Voltage Comparison.
Battery-Powered Sensor Conditioning
The MCP616-I/P fits battery-powered sensor conditioning because its typical operating current is only 19 µA and its single-supply range begins at 2.3 V. The amplifier can provide gain or buffering for slow-moving sensor signals without requiring a dual supply. Its typical offset voltage below 150 µV is useful when the source impedance and signal amplitude make offset error significant. The design should use the rail-to-rail output to maximize usable signal range, while checking the manufacturer datasheet for input common-mode limits and load-current capability.
Recomendado
Portable Medical Monitoring
The MCP616-I/P is a candidate for portable medical-monitoring signal paths that require low power and a single low-voltage rail. Its 19 µA typical operating current helps limit energy use in battery-powered instruments, while the 2.3 V to 5.5 V supply range supports compact system architectures. The less-than-150 µV typical offset voltage can help preserve small physiological signals. Medical use still requires system-level validation of noise, leakage, patient protection, applicable standards, and qualification requirements; the amplifier alone does not establish medical compliance.
Recomendado
Low-Frequency Active Filters
The MCP616-I/P can implement low-frequency active filters when the signal bandwidth is well below its 190 kHz gain-bandwidth product. Its typical operating current of 19 µA reduces the power burden of always-on filtering, and the single 2.3 V to 5.5 V supply simplifies portable filter implementations. Designers should select closed-loop gain with adequate bandwidth margin and verify capacitor and resistor tolerances against the required cutoff accuracy. The listed 0.08 V/µs slew rate also determines large-signal behavior and settling time.
Recomendado
Industrial Threshold Detection
The MCP616-I/P is appropriate for low-power threshold detection in industrial monitoring when the decision signal can be compared against a reference. A 190 kHz gain-bandwidth product provides more bandwidth than is normally required for slow process-variable changes, while the 19 µA typical current supports long operating intervals. The rail-to-rail output helps drive downstream logic when the comparison result must approach the supply limits. Engineers should still check output-drive limits, noise around the threshold, input offset over temperature, and system grounding before deployment.
Recomendado
Portable Instrumentation Buffering
The MCP616-I/P works as a high-impedance buffer ahead of an ADC or measurement front end when power consumption is more important than high bandwidth. Its low bias current is particularly valuable with high-source-impedance sensors, while the less-than-150 µV typical offset reduces additive signal error. The device operates from 2.3 V to 5.5 V, allowing a buffered node to share a compact system rail. Layout should minimize leakage from the input pin and preserve a low-impedance reference return, while datasheet verification is needed for exact input-bias-current limits.
Recomendado
Low-Power Voltage Comparison
The MCP616-I/P can compare a low-voltage signal with a reference in battery-operated equipment because it supports single-supply operation down to 2.3 V. The 19 µA typical operating current helps preserve battery life, and the rail-to-rail output allows the comparison result to use more of the available supply range. A practical design should account for input offset, reference accuracy, noise, and propagation delay. The listed 190 kHz gain-bandwidth product supports signals well above basic static threshold detection while remaining focused on low-power analog performance.

Notas de diseño
Place the supply-bypass capacitor as close as practical to the V+ and V- pins, and route V- directly to the quiet ground reference. Because the MCP616-I/P is intended for micropower operation, capacitor leakage can be significant relative to its 19 µA typical operating current. Select a low-leakage bypass capacitor where battery life is critical, and verify the capacitor's DC bias derating because its effective capacitance may fall below its nominal value.
Keep the inverting input and feedback components away from switching nodes, clock traces, and the positive supply pin. For high-impedance sensors, shorten the non-inverting input trace, minimize solder-surface leakage, and avoid routing beneath noisy digital signals. A solid ground reference is more important than geometric symmetry in many low-power designs. These precautions help preserve the benefit of the MCP616's low bias current, whose exact value should be confirmed in the manufacturer datasheet.
Do not interpret rail-to-rail output as unrestricted input range or unlimited output drive. Confirm the input common-mode limits, output-current capability, capacitive-load stability, and channel-specific electrical limits in the current manufacturer datasheet. In addition, a candidate alternative must be checked for pin-function differences: MCP618-I/P adds chip select, and MCP617-I/P is a dual amplifier, so neither should be substituted solely because its package matches the 8-pin PDIP footprint.
