45 V, 2 MHz Zero-Drift Op-amp with EMI Filtering


  • High DC Precision
  • Low Noise & Low Power
  • Easy to Use
  • Small Packages

The MCP6V51 operational amplifier employs dynamic offset correction for very low offset and offset drift.

The device has a gain-bandwidth product of 2 MHz (typical). It is unity-gain stable, has virtually no 1/f noise, excellent Power Supply Rejection Ratio (PSRR) and Common Mode Rejection Ratio (CMRR). The device operates with a single supply voltage that can range from 4.5V to 45V, (±2.25V to ±22.5V) while drawing 470 µA (typical) of quiescent current.

The MCP6V51 op-amp is offered as a single-channel amplifier and is designed using an advanced CMOS process.
