MCP603-I/P - 2.7V, 2.8MHz CMOS Op Amp | Microchip
Артикул: MCP603-I/P ✓ АктивенMCP603-I/P Обзор
An operational amplifier is a high-gain analog building block used in the amplifier hierarchy and wider signal-processing systems. Its differential input stage, feedback network, and output stage support voltage amplification, filtering, buffering, comparison, and current-control functions. The MCP603 combines CMOS characteristics with low-power single-supply operation, making it relevant to portable, battery-powered, industrial, instrumentation, and general-purpose analog designs.
The MCP603 family's headline benefits are its low-power operation, 2.8 MHz bandwidth, rail-to-rail output swing, and chip-select control. Advanced CMOS technology provides low bias current and high open-loop gain, while the single amplifier makes the device economical where one buffered or amplified channel is sufficient. Its general-purpose positioning supports signal processing rather than precision-reference or high-current drive functions.
According to the verified distributor data, the device is a one-circuit rail-to-rail amplifier in an 8-DIP package measuring 0.300 inches, or 7.62 mm. The listed 2.3 V/us slew rate supports moderate-frequency waveform generation and signal conditioning. The chip-select feature is useful when multiple shared-bus or shared-signal arrangements require the amplifier output to be placed in a controlled state.
Typical applications include sensor-signal conditioning, low-power analog filtering, buffered ADC inputs, portable instrumentation, signal buffering, and general low-frequency control loops. Because the available data does not provide every electrical limit or pin assignment, engineers should consult the official Microchip MCP603 product page and datasheet before finalizing gain, noise, common-mode, output-load, and selection logic.
For PCB design, preserve short analog input paths, provide a stable supply reference, and place input and output decoupling near the device. Avoid substituting a package or pinout based only on an amplifier-function match; the 8-pin PDIP footprint, pin mapping, supply range, and electrical limits must all be verified.
This page combines verified manufacturer and distributor information, sourced commercial data, and engineering guidance for MCP603-I/P selection. Because the supplied data does not establish five same-package drop-in replacements or complete pricing, missing values remain explicitly identified rather than guessed.

Типичное применение
MCP603-I/P подходит для 6 применениеs: Low-Power Sensor Signal Conditioning, Portable Analog Filtering, Buffered ADC Input, General-Purpose Instrumentation, Low-Voltage Waveform Conditioning, Portable Test and Measurement.
Low-Power Sensor Signal Conditioning
The MCP603-I/P fits low-power sensor-conditioning circuits that need modest bandwidth and rail-to-rail output swing. Its verified 2.7 V minimum operating supply and less-than-325-uA quiescent current suit battery-powered instrumentation, while the 2.8 MHz gain-bandwidth product provides more bandwidth than a purely ultra-low-frequency precision amplifier. Place the amplifier around the sensor signal with feedback components selected for the target gain and bandwidth. Confirm input common-mode limits, bias current, offset, noise, and output-load behavior against the manufacturer datasheet before finalizing the gain plan.

Portable Analog Filtering
MCP603-I/P is a practical choice for portable analog filters that must operate from a low supply and conserve battery current. Its CMOS implementation, 2.8 MHz gain-bandwidth product, and 2.3 V/us slew rate support active filtering and modest signal-bandwidth requirements. The rail-to-rail output can improve utilization of a restricted analog range, although the exact usable swing depends on load and supply. Select resistor and capacitor values after checking closed-loop stability, gain-bandwidth interaction, and the device's verified input and output limits.
Рекомендуется
Buffered ADC Input
The MCP603-I/P can buffer a sensor or divider into an ADC input when the system needs a single rail-to-rail output amplifier with approximately 2.8 MHz gain-bandwidth product. The device is especially relevant to low-voltage embedded designs because it operates from 2.7 V and draws less than 325 uA quiescent current. Use a resistor divider or feedback network to establish the required ADC range, and verify the amplifier's settling behavior, output drive, capacitive-load limits, and acquisition-window requirements. The official datasheet is required for exact dynamic and load specifications.
Рекомендуется
General-Purpose Instrumentation
MCP603-I/P is suitable for instrumentation modules that combine a low-voltage analog front end with a small microcontroller or measurement controller. Its high open-loop gain, low bias current, CMOS low-power behavior, and rail-to-rail output support amplification of moderate-bandwidth signals without requiring a dual supply. The single amplifier allows a simple instrumentation design when only one active channel is required. Validate offset, input bias current, noise density, common-mode behavior, and output settling against the actual sensor impedance and measurement bandwidth.
Рекомендуется
Low-Voltage Waveform Conditioning
The MCP603-I/P can condition small, low-frequency waveforms where its 2.3 V/us slew rate and 2.8 MHz gain-bandwidth product provide useful bandwidth. Rail-to-rail output operation is helpful when the waveform must use a substantial portion of a 2.7 V supply range. Use the amplifier in an inverting or non-inverting topology with feedback resistors that account for the package and circuit parasitics. Check output swing, load, stability with capacitive loads, and gain accuracy before using it for precision waveform generation.
Рекомендуется
Portable Test and Measurement
MCP603-I/P is appropriate for compact test and measurement equipment where one general-purpose amplifier must operate from a low supply. Its single-channel architecture simplifies the analog channel count, and its under-325-uA maximum quiescent current supports battery-operated instruments. The amplifier can buffer probes, scale sensor outputs, or implement active filtering, provided the source impedance does not exceed the verified input-bias and noise requirements. Review the manufacturer's electrical characteristics for accuracy and settling before assigning measurement uncertainty to the circuit.

Заметки по проектированию
The verified MCP603-I/P operating supply begins at 2.7 V, and the family description identifies less than 325 uA quiescent current. Keep the bypass capacitor path short and place the device ground return close to the supply reference. Do not use the minimum supply as a design target without checking the complete datasheet limits for input common-mode range, output swing, and load current.
Treat the input path as a precision analog signal even though the MCP603-I/P is a general-purpose amplifier. Route sensor and feedback connections away from switching nodes and digital return currents, use a continuous ground reference, and avoid long traces between the source, amplifier, and feedback network. The supplied data does not expose the pinout, so verify every connection against the manufacturer datasheet before layout release.
Do not substitute a similarly rated 8-DIP amplifier solely because the package count matches. Verify pin numbering, chip-select behavior, input common-mode range, rail-to-rail claims, bandwidth, slew rate, bias current, and supply limits. The verified MCP603-I/P data is sufficient to identify the family, but it does not establish that an LMV321 or another candidate is a true pin-to-pin replacement.
Информация о соответствии
The supplied manufacturer and distributor snippets do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance values therefore remain unknown rather than inferred from package type or general-purpose product classification.
