Data SheetADCMP551/ADCMP552/ADCMP553Pin No.ADCMP551ADCMP552ADCMP553Mnemonic Description 13 16 LEB One of Two Complementary Inputs for Channel B Latch Enable. In compare mode (logic high), the output tracks changes at the input of the comparator. In latch mode (logic low), the output reflects the input state just prior to the comparator being placed into latch mode. LEB must be driven in conjunction with LEB. 15 18 QB One of Two Complementary Outputs for Channel B. QB is logic low if the analog voltage at the noninverting input is greater than the analog voltage at the inverting input (provided the comparator is in the compare mode). See the description of Pin LEB for more information. 16 19 QB One of Two Complementary Outputs for Channel B. QB is logic high if the analog voltage at the noninverting input is greater than the analog voltage at the inverting input (provided the comparator is in the compare mode). See the description of Pin LEB for more information. 7 VCC Positive Supply Terminal. Rev.
