Note 1:
The MCP652 single, MCP653 single, MCP655 dual and MCP659 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 MCP655 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 tog- gled 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 MCP659 quad, there is an additional constraint. CALAD/CSAD and CALBC/CSBC can be toggled simultane- ously (within a time much smaller than tCSU) to make all four op amps perform the same function simultaneously, and the maximum t time is approximately doubled (8 ms). If they are toggled independently, then CAL CON AD/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.
