Key Features
- Quad op-amp channels in a single 14-pin SOIC-14 package, reducing BOM count and PCB area
- 1.6 V minimum supply voltage supporting single-cell battery and low-voltage rail designs
- 0.005 µA maximum input bias current for high-impedance sensor interfacing with minimal loading
Applications
The MCP6144-I/SL suits battery-powered multi-channel signal conditioning systems, such as portable medical diagnostics and environmental sensing modules, that require 4 independent amplifiers from a single 1.6 V supply. Its low bias current makes it ideal for interfacing pH electrodes, photodiodes, and other high-impedance transducers without signal corruption. Industrial multi-axis sensor front ends and active multi-pole filter chains also benefit from the quad topology in the compact SOIC-14 footprint.

Frequently Asked Questions
How many amplifier channels does the MCP6144-I/SL integrate, and what is the package size?
The MCP6144-I/SL integrates 4 independent op-amp channels in a single 14-pin SOIC-14 package measuring approximately 8.7 mm x 3.9 mm. This quad topology consolidates what would otherwise require four separate single-channel devices, cutting BOM count and occupied PCB area by roughly 60 to 75 percent in multi-channel sensor conditioning designs.
At what minimum supply voltage can the MCP6144-I/SL operate, and how does that benefit portable designs?
The MCP6144-I/SL operates from a minimum supply of 1.6 V, which covers single-cell alkaline batteries at end-of-life and regulated outputs from low-dropout regulators. In portable environmental loggers or wearable monitors, this means the quad amplifier remains functional even as the battery depletes below 2 V, extending the usable device lifetime without requiring a boost converter.
What gain-bandwidth product does the MCP6144-I/SL offer, and which filter designs does it support?
The MCP6144-I/SL provides a 100 kHz gain-bandwidth product, which is sufficient for audio-frequency and low-speed sensor signal chains operating below 10 kHz. A single 14-pin package can implement a 4-pole Sallen-Key or multiple-feedback active filter without any external op-amps, supporting anti-aliasing stages ahead of a 12-bit ADC in data logging and medical telemetry applications.
When should an engineer choose MCP6144-I/SL over a rail-to-rail op-amp for a high-impedance sensor interface?
The MCP6144-I/SL is the right choice when the sensor source impedance exceeds 10 MΩ and supply current must stay in the low-microamp range, because its 0.005 µA maximum input bias current causes less than 50 µV of offset error even with a 10 MΩ source. Rail-to-rail devices often trade higher bias currents for output swing, which would introduce unacceptable loading on pH probes or piezoelectric sensors.
