Key Features
- Ultra-low bias current of 50 pA max, enabling high-impedance sensor interfaces
- High CMRR of 90 dB typical (75 dB min) for excellent noise rejection in differential signal paths
- Quad-channel voltage-feedback op-amp in compact SOIC-14 package for space-constrained PCB layouts
Applications
The MCP6424-E/SL suits precision analog front-end designs where four amplifier channels must fit in a compact SOIC-14 footprint, such as medical instrumentation, sensor signal conditioning, and multi-channel data acquisition systems. Its 75 dB minimum CMRR and 50 pA bias current make it well-suited for electrochemical sensor interfaces and high-impedance photodiode amplifiers. The quad channel configuration reduces BOM count in multi-sensor designs requiring 4 independent amplifier stages.

Frequently Asked Questions
What is the bias current specification of MCP6424-E/SL and how does it affect high-impedance sensor designs?
The MCP6424-E/SL has a maximum bias current of 50 pA at 25°C, which is extremely low and ideal for high-impedance sensors such as photodiodes and pH electrodes. With such low bias current, the voltage error introduced across source impedances of 1 MΩ or more is kept well below 50 µV, preserving measurement accuracy across all 4 channels in multi-sensor systems.
How does the MCP6424-E/SL CMRR performance compare to general-purpose quad op-amps in noisy industrial environments?
The MCP6424-E/SL delivers a typical CMRR of 90 dB (minimum 75 dB), which is higher than many general-purpose quad op-amps that often specify only 60 dB to 70 dB minimum. This 90 dB rejection effectively attenuates common-mode noise from 50 Hz or 60 Hz power lines by a factor exceeding 30,000:1, making it suitable for industrial sensor signal conditioning where electromagnetic interference is prevalent.
For a 4-channel ECG front-end design, does the MCP6424-E/SL SOIC-14 package offer meaningful board-space savings over discrete single op-amps?
Yes, the SOIC-14 package integrates 4 amplifier channels in a single 14-pin footprint measuring approximately 8.65 mm × 3.9 mm, compared to using four individual SOT-23 or SOIC-8 single op-amps that would consume roughly 3× to 4× the total board area. This consolidation also simplifies routing and reduces solder joint count by 18 to 24 joints in a typical 4-channel layout.
