MCP6042-E/P - Dual 1.4V RRIO Op Amp | Microchip Technology
料号： MCP6042-E/P ✓ 量产中MCP6042-E/P 概述
An operational amplifier, or op amp, is a high-gain differential amplifier used to amplify, buffer, filter, or control signals. The MCP6042 belongs to the general-purpose amplifier hierarchy within analog integrated circuits. Its rail-to-rail inputs and outputs allow operation close to the supply rails, while the low 1.4 V minimum supply supports battery-powered and energy-conscious portable equipment.
The MCP6042-E/P uses a 1.4 V to 6 V supply range, less than 1.0 µA of quiescent current per amplifier, and a 14 kHz gain-bandwidth product. Rail-to-rail input and output behavior increases usable signal range in single-supply systems. The dual configuration reduces the component count when two independent analog channels are required, while the 8-pin PDIP package supports through-hole assembly and prototyping.
This low-power amplifier trades bandwidth and slew rate for very low supply consumption. A 14 kHz gain-bandwidth product is sufficient for slow sensor signals, process-control loops, and low-frequency conditioning rather than high-speed signal processing. The 0.003 V/µs slew rate similarly favors precision and low-frequency applications where fast large-signal transitions are not required.
Typical uses include portable instrumentation, industrial process-control interfaces, battery-operated sensors, wearable devices, and low-frequency filtering. Its rail-to-rail characteristics are especially useful when sensor signals occupy much of the available input range, and its dual circuit count can lower board area in stereo sensing, dual-channel measurement, or signal-conditioning systems.
Designers should verify the input and output common-mode range at the selected supply voltage and confirm that the 14 kHz bandwidth and 0.003 V/µs slew rate satisfy the required settling time. Decoupling capacitors should be placed close to the supply pins, and unused amplifier inputs must be configured according to the manufacturer guidance.
This product data consolidates verified distributor specifications, same-package replacement options, application guidance, and design considerations. It also distinguishes documented parameters from unverified details so engineers can make sourcing and design decisions without relying on incomplete marketplace summaries.

典型应用
MCP6042-E/P 适用于 6 应用s: Battery-Powered Sensor Conditioning, Industrial Process Measurement, Portable Wearable Electronics, Low-Frequency Active Filtering, Dual-Channel Signal Buffering, Low-Power Control Loops.
Battery-Powered Sensor Conditioning
The MCP6042-E/P fits low-power sensor interfaces because it operates from a single supply as low as 1.4 V and consumes less than 1.0 µA of quiescent current per amplifier. Its two channels can condition complementary or sequential sensor signals while conserving battery capacity. The 14 kHz gain-bandwidth product is appropriate for slow temperature, pressure, and chemical sensors, but applications requiring rapid settling should use a faster amplifier. Input bias current and offset were not present in the verified data and must be checked before selecting the gain for high-impedance sources.
推荐
Industrial Process Measurement
The MCP6042-E/P can amplify and buffer slow industrial process signals when the design operates from a 1.4 V to 6 V supply. Its dual-circuit configuration supports two measurement channels, such as a sensor input and a feedback or reference path, while rail-to-rail operation improves utilization of the available signal range. The 0.003 V/µs slew rate and 14 kHz bandwidth suit low-frequency control and monitoring signals rather than wideband communications. Verify noise, offset, stability, and the complete temperature range for the selected ordering code.
推荐
Portable Wearable Electronics
The MCP6042-E/P suits portable and wearable electronics where supply voltage and current consumption are tightly constrained. A 1.4 V minimum operating voltage allows use with low-energy cells, while the dual amplifier arrangement provides two analog channels in one 8-pin PDIP footprint. Rail-to-rail inputs and outputs help maintain signal range in compact systems. The relatively low 14 kHz bandwidth is appropriate for physiological or environmental monitoring signals, but the through-hole PDIP package is primarily intended for prototypes or assemblies that accept through-hole components.
推荐
Low-Frequency Active Filtering
The MCP6042-E/P is suitable for low-frequency active filters because it provides two amplifiers, rail-to-rail operation, and a 14 kHz gain-bandwidth product. It can implement smoothing or gain stages around sensors where the signal bandwidth remains well below the amplifier's capability. The 0.003 V/µs slew rate supports gradual waveform transitions but limits large-signal performance. Exact filter component values require input and output impedance, noise, offset, and stability data from the manufacturer datasheet, none of which was included in the verified search excerpts.
推荐
Dual-Channel Signal Buffering
The MCP6042-E/P can buffer two independent low-frequency analog channels within one package. Rail-to-rail input and output characteristics are useful when the source and destination share a restricted 1.4 V to 6 V supply, while the dual configuration reduces the number of amplifier packages required. The amplifier's 14 kHz gain-bandwidth product is adequate for many sensor, control, and instrumentation signals. For precision bridges, high source impedances, or stringent settling requirements, verify input bias current, offset voltage, noise, and stability before finalizing the design.
推荐
Low-Power Control Loops
The MCP6042-E/P can serve simple control and feedback functions in low-voltage systems because its two amplifiers share one package and its quiescent current is less than 1.0 µA per amplifier. The 1.4 V to 6 V supply range permits operation close to a low-energy power source, while rail-to-rail behavior improves output utilization. Its 14 kHz bandwidth and 0.003 V/µs slew rate are suitable for slow proportional control loops rather than fast motor or power-converter control. Compensation values and stability margins require the complete datasheet characteristics.

设计说明
Calculate the complete analog power budget before using the MCP6042-E/P in a battery-powered design. The verified family specification states less than 1.0 µA of quiescent current per amplifier, but sensor biasing, divider currents, ADC reference loads, and leakage can dominate the system budget. Decouple each supply rail close to the relevant pins and confirm the selected capacitor's effective bias behavior across the full 1.4 V to 6 V operating range.
Treat the MCP6042-E/P as a low-bandwidth amplifier. Its 14 kHz gain-bandwidth product and 0.003 V/µs slew rate can become the limiting elements in a filter, control loop, or instrumentation amplifier. Check the closed-loop gain, required signal amplitude, settling time, and output capacitive loading against the manufacturer characteristic curves. Use a higher-bandwidth amplifier when the signal contains frequencies or fast transitions beyond this device's intended range.
Do not assume that a family member with a different package suffix is a PCB drop-in replacement. MCP6042 options are offered in PDIP, SOIC, and MSOP packages, so SOIC and MSOP variants require different land patterns even if their basic electrical ratings are similar. For an existing MCP6042-E/P board, restrict substitution to an explicitly verified 8-pin PDIP device and confirm channel assignment, supply pins, and input configuration.
Keep the 8-pin PDIP footprint in a conventional through-hole layout and route sensitive amplifier inputs away from switching nodes and high-current return paths. Provide local supply bypassing, use a low-noise ground reference, and avoid long input traces that can increase noise pickup. Because no recommended external compensation or decoupling values were included in the verified excerpts, use the current manufacturer datasheet and reference layouts for final component selection.
合规信息
The verified excerpts did not provide explicit compliance declarations. The Arrow listing contains an automotive-related descriptor, but it does not provide enough first-party evidence to assign an AEC-Q100 qualification status to this exact ordering code.
