DD As seen in Figures 1 and 2, the MCP6V61/1U/2/4 op amps have excellent performance across temperature. The input offset voltage temperature drift (TC ) shown 1 is well within the specified maximum values of 15 nV/C at V = 5.5V and 30 nV/C at V =1.8V. DD DD This performance supports applications with stringent DC precision requirements. In many cases, it will not be necessary to correct for temperature effects (i.e., calibrate) in a design. In the other cases, the correction will be small. DS20005367B-page 2 2014-2015 Microchip Technology Inc. Input Offset Voltage (V) Input Offset Voltage (V)
