Key Features

  • Single voltage-feedback op amp with 1.8V low-voltage operation and 300kHz gain-bandwidth product ideal for battery-powered signal conditioning
  • Ultra-low 1.1nA maximum input bias current enabling high-impedance sensor interfacing with minimal signal loading errors
  • 75dB typical CMRR (61dB minimum) providing strong common-mode noise rejection for precision measurement applications
  • Compact DFN-8 package with REACH-compliant, RoHS lead-free construction for high-density portable and industrial PCB designs

Applications

The MCP6231-E/MC is ideal for signal conditioning, sensor buffering, and active filtering in low-power portable instruments, wearables, and battery-operated IoT devices where 1.8V operation is required. Its ultra-low bias current makes it well suited for interfacing with high-impedance sensors such as pH electrodes, photodiodes, and capacitive transducers in precision measurement systems. It is also used in medical monitoring devices, handheld meters, and audio processing circuits requiring a compact, low-noise op amp with minimal power consumption.

Frequently Asked Questions

What are the key specifications of the MCP6231-E/MC op amp?

The MCP6231-E/MC is a single voltage-feedback op amp operating at 1.8V with a 300kHz gain-bandwidth product, a maximum input bias current of 1.1nA, and a typical CMRR of 75dB (minimum 61dB), making it suitable for low-power precision signal conditioning applications.

What temperature range does the MCP6231-E/MC support?

The MCP6231-E/MC is rated for the extended industrial temperature range (E grade), covering -40°C to +125°C, ensuring reliable operation in demanding environmental conditions found in industrial sensors, automotive accessories, and outdoor IoT deployments.

What package does the MCP6231-E/MC use?

The MCP6231-E/MC comes in a DFN-8 (Dual Flat No-Lead, 8-pin) package offering a compact, low-profile footprint with excellent thermal and electrical performance, ideal for space-constrained portable and wearable electronics requiring a small single op amp.

Why is the low input bias current of the MCP6231-E/MC important?

The MCP6231-E/MC's maximum input bias current of 1.1nA is critical for applications interfacing with high-impedance signal sources such as pH sensors, photodiodes, and capacitive transducers, where higher bias currents would introduce measurement errors and reduce accuracy.

Is the MCP6231-E/MC RoHS compliant and what is its lead-free status?

Yes, the MCP6231-E/MC is designated as Pb-free and is REACH compliant, meeting international environmental regulations. It is suitable for use in RoHS-regulated consumer, industrial, and medical products requiring lead-free components.
