Pin No.

ADCMP561 ADCMP562 Mnemonic Function

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 placing the comparator in the latch mode.

LEB

must be

driven in conjunction with LEB. If left unconnected, the comparator defaults to compare mode.

14 17 GND Analog Ground.

15 18

One of two complementary outputs for Channel B.

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 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 compare mode). See the description of Pin LEB for more information.
