GENERAL DESCRIPTION
The AD9696 and AD9698 are ultrafast TTL-compatible volt-
age comparators able to achieve propagation delays previously
possible only in high performance ECL devices. The AD9696 is
a single comparator providing 4.5 ns propagation delay, 200 ps
maximum delay dispersion and 1.7 ns setup time. The AD9698
is a dual comparator with equally high performance; both de-
vices are ideal for critical timing circuits in such applications as
ATE, communications receivers and test instruments.
Both devices allow the use of either a single +5 V supply or
± 5 V supplies. The choice of supplies determines the common
mode input voltage range available: –2.2 V to +3.7 V for ± 5 V
operation, +1.4 V to +3.7 V for single +5 V supply operation.
The differential input stage features high precision, with offset
voltages that are less than 2 mV and offset currents less than
1 µA. A latch enable input is provided to allow operation in ei-
ther sample-and-hold or track-and-hold applications.
The AD9696 and AD9698 are both available as commercial
temperature range devices operating from ambient temperatures
of 0°C to +70°C, and as extended temperature range devices for
ambient temperatures from –55°C to +125°C. Both versions are
available qualified to MIL-STD-883 class B.
Package options for the AD9696 include a 10-pin TO-100 metal
can, an 8-pin ceramic DIP, an 8-pin plastic DIP, and an 8-lead
small outline plastic package. The AD9698 is available in a
16-pin ceramic DIP, a 16-lead ceramic gullwing, a 16-pin plastic
DIP and a 16-lead small outline plastic package. Military quali-
fied versions of the AD9696 come in the TO-100 can and
ceramic DIP; the dual AD9698 comes in ceramic DIP.
