Typical Application Circuit

Figures 1 and 2 show input offset voltage versus ambi-

ent temperature for different power supply voltages.

FIGURE 1:

Input Offset Voltage vs.

Ambient Temperature with VDD =1.8V.

FIGURE 2:

Input Offset Voltage vs.

Ambient Temperature with VDD =5.5V.

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 (TC1) shown

is well within the specified maximum values of

15 nV/°C at VDD = 5.5V and 30 nV/°C at VDD =1.8V.

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.
