Note 1:
The MCP622 single, MCP625 dual and MCP629 quad have their CAL/CS inputs internally pulled down to VSS (0V).
2:
This time ensures that the internal logic recognizes the edge. However, for the rising edge case, if CAL/CS is raised before the calibration is complete, the calibration will be aborted and the part will return to Low-Power mode.
3:
For the MCP625 dual, there is an additional constraint. CALA/CSA and CALB/CSB can be toggled simultaneously (within a time much smaller than tCSU) to make both op amps perform the same function simultaneously. If they are toggled independently, then CALA/CSA (CALB/CSB) cannot be allowed to toggle while op amp B (op amp A) is in Calibration mode; allow more than the maximum tCON time (4 ms) before the other side is toggled.
4:
For the MCP629 quad, there is an additional constraint. CALAD/CSAD and CALBC/CSBC can be toggled simultaneously (within a time much smaller than tCSU) to make all four op amps perform the same function simultaneously, and the maximum tCON time is approximately doubled (8 ms). If they are toggled independently, then CALAD/CSAD (CALBC/CSBC) cannot be allowed to toggle while op amps B and C (op amps A and D) are in Calibration mode; allow more than the maximum tCON time (8 ms) before the other side is toggled.  2009-2014 Microchip Technology Inc.
