General Description

The Microchip Technology MCP6V51/2/4 operational

amplifiers employ dynamic offset correction for very

low offset and offset drift. These devices have a gain

bandwidth product of 2 MHz (typical). They are unity

gain stable, have virtually no 1/f noise and excellent

Power Supply Rejection Ratio (PSRR) and Common-

Mode Rejection Ratio (CMRR). These products

operate with a single or dual supply voltage that can

range from 4.5V to 45V (±2.25V to ±22.5V), while

drawing 470 μA/amp (typical) of quiescent current.

The MCP6V51/2/4 op amps are offered as single, dual

and quad channel amplifiers, and are designed using

an advanced CMOS process.
