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

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 and excellent Power Supply Rejection Ratio (PSRR) and Common Mode Rejection Ratio (CMRR). The product 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.
