under any of these conditions is not necessarily implied. Exposure to absolute

Description
Positive supply terminal, nominally 5.0 V.
Noninverting analog input of the differential input stage. The NONINVERTING INPUT must be
driven in conjunction with the INVERTING INPUT.
Inverting analog input of the differential input stage. The INVERTING INPUT must be driven in
conjunction with the NONINVERTING INPUT.
In the “compare” mode (logic HIGH), the output will track changes at the input of the compara-
tor. In the “latch” mode (logic LOW), the output will reflect the input state just prior to the
comparator being placed in the “latch” mode. LATCH ENABLE must be driven in conjunction
with LATCH ENABLE for the AD96687.
In the “compare” mode (logic LOW), the output will track changes at the input of the comparator.
In the “latch” mode (logic HIGH), the output will reflect the input state just prior to the comparator
being placed in the “latch” mode. LATCH ENABLE must be driven in conjunction with
LATCH ENABLE for the AD96687.
Negative supply terminal, nominally –5.2 V.
One of two complementary outputs. Q will be at logic HIGH if the analog voltage at the
NONINVERTING INPUT is greater than the analog voltage at the INVERTING INPUT (pro-
vided the comparator is in the “compare” mode). See LATCH ENABLE and LATCH ENABLE
(AD96687 only) for additional information.

NONINVERTING INPUT is greater than the analog voltage at the INVERTING INPUT
(provided the comparator is in the “compare” mode). See LATCH ENABLE and LATCH ENABLE

One of two grounds, but primarily associated with the digital ground. Both grounds should be
connected together near the comparator.
