Key Features

  • Ultra-low supply voltage operation starting from 1.6V for battery-powered designs
  • Low input bias current max 5 nA suitable for high-impedance sensor interfaces
  • 62 dB minimum CMRR and 80 dB typical for reliable differential signal rejection
  • Compact 8-Pin SOIC package for space-efficient PCB layouts

Applications

The MCP6143-I/SN is ideal for ultra-low-power portable devices such as wearables, remote sensors, and medical monitors where supply voltage as low as 1.6V is critical. Its low bias current and 100 kHz bandwidth make it well suited for photodiode amplifiers, battery-level indicators, and signal conditioning in low-frequency measurement systems. Industrial sensor interfaces and consumer electronics also benefit from its wide temperature range and small footprint.
