Applications
MCP6144-I/P is used in multi-channel sensor front-ends such as pressure, temperature, and strain gauge bridges where four independent low-power amplifiers reduce board area and component count. It is also suited for active low-pass filters, DAC output buffers, and comparator-free threshold detection circuits in battery-powered industrial and consumer devices.

Frequently Asked Questions
How many op amp channels does MCP6144-I/P contain and what supply voltages does it support?
MCP6144-I/P integrates 4 independent op amp channels in a single 14-pin PDIP package and operates from single-supply voltages of 3 V or 5 V. Having 4 amplifiers in one package reduces BOM count compared to using four individual single op amps, saving board space and cost.
What bandwidth does MCP6144-I/P offer and is it adequate for filtering audio-range sensor signals?
MCP6144-I/P has a gain-bandwidth product of 100 kHz, which limits unity-gain bandwidth to 100 kHz and closed-loop bandwidth at a gain of 10 to approximately 10 kHz. This is sufficient for filtering DC to low-frequency sensor signals up to a few kilohertz but is not suitable for audio or RF amplification tasks.
When would a designer choose MCP6144-I/P over MCP6272-E/P for a 4-channel sensor application?
MCP6144-I/P provides 4 amplifier channels in a 14-pin PDIP versus 2 channels in MCP6272's 8-pin package. For a 4-channel design, using MCP6144-I/P reduces the PCB footprint by half and cuts component placements, making it the preferred choice when four identical gain stages with 5 nA bias current and 3 V to 5 V operation are all needed simultaneously.
What input bias current does MCP6144-I/P specify and how does it benefit resistive bridge sensor interfaces?
MCP6144-I/P has a maximum average input bias current of 5 nA, which generates less than 0.5 µV of offset voltage when connected to a 100 kΩ source resistance. This extremely low bias current allows direct connection to Wheatstone bridge outputs and other high-impedance resistive sensors without introducing significant DC measurement error.
