Key Features
- Quad rail-to-rail input and output op-amp in 14-pin PDIP package
- Ultra-low 0.1 nA maximum input bias current for high-impedance sensor interfaces
- 80 dB typical common-mode rejection ratio (CMRR) for noise-immune signal paths
- Wide supply range from 1.4 V to 6 V enabling single-cell to dual-cell battery operation
- Unity-gain stable voltage-feedback architecture with internal frequency compensation
Applications
The MCP6044-I/P is ideal for portable medical instruments, battery-powered data loggers, and industrial sensor front-ends where low bias current and rail-to-rail swing on a single 1.8 V to 5 V supply are required. Its four op-amp channels in one package reduce component count in multi-channel signal conditioning circuits, pH sensors, and bridge amplifier designs.

Frequently Asked Questions
How low is the input bias current of the MCP6044-I/P, and why does that matter for high-impedance sensor circuits?
The MCP6044-I/P specifies a maximum input bias current of 0.1 nA (0.0001 µA), which is among the lowest in voltage-feedback op-amps. At this level, even a 10 MΩ source impedance produces only 1 mV of offset error, making the device suitable for pH electrodes, photodiodes, and capacitive humidity sensors.
What supply voltage range does the MCP6044-I/P support, and can it run from a single 3.3 V rail?
The MCP6044-I/P operates from 1.4 V to 6 V total supply, covering single-supply rails from 1.4 V to 6 V or split ±0.7 V to ±3 V configurations. A 3.3 V single rail is squarely within the rated range, allowing seamless integration with 3.3 V MCUs without additional supply regulation.
How does the MCP6044-I/P's CMRR specification affect noisy industrial signal acquisition?
The MCP6044-I/P achieves a typical CMRR of 80 dB, meaning a 1 V common-mode noise signal is attenuated to roughly 100 µV at the output. This rejection level is suitable for 4–20 mA industrial sensor loops and differential bridge measurements operating in electrically noisy factory environments.
When should a designer choose the MCP6044-I/P PDIP-14 over surface-mount versions for prototyping?
The 0.300-inch PDIP-14 through-hole package is preferred during breadboard or DIP-socket prototyping phases where engineers swap op-amp variants without PCB rework. Four amplifiers per package means a single MCP6044-I/P can fill a complete 4-channel instrumentation amplifier input stage on a prototyping board.
Is the MCP6044-I/P RoHS compliant, and what is its expected product lifecycle status?
Yes, the MCP6044-I/P is manufactured as a lead-free, RoHS-compliant device meeting JEDEC moisture sensitivity standards. Microchip lists the part as active with a factory lead time of approximately 6 weeks, providing reasonable supply continuity for production designs requiring the PDIP-14 form factor.
