TTL Comparators
AD9696/AD9698
FEATURES
4.5 ns Propagation Delay
200 ps Maximum Propagation Delay Dispersion
Single +5 V or
6
5 V Supply Operation
Complementary Matched TTL Outputs
APPLICATIONS
High Speed Line Receivers
Peak Detectors
Window Comparators
High Speed Triggers
Ultrafast Pulse Width Discriminators
Both devices allow the use of either a single +5 V supply or
±
5 V supplies. T he 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.
T he differential input stage features high precision, with offset
voltages that are less than 2 mV and offset currents less than
1
μ
A. A latch enable input is provided to allow operation in ei-
ther sample-and-hold or track-and-hold applications.
T he 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-ST D-883 class B.
Package options for the AD9696 include a 10-pin T O-100 metal
can, an 8-pin ceramic DIP, an 8-pin plastic DIP, and an 8-lead
small outline plastic package. T he 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 T O-100 can and
ceramic DIP; the dual AD9698 comes in ceramic DIP.
GE NE RAL DE SCRIPT ION
T he AD9696 and AD9698 are ultrafast T T L-compatible volt-
age comparators able to achieve propagation delays previously
possible only in high performance ECL devices. T he AD9696 is
a single comparator providing 4.5 ns propagation delay, 200 ps
maximum delay dispersion and 1.7 ns setup time. T he AD9698
is a dual comparator with equally high performance; both de-
vices are ideal for critical timing circuits in such applications as
AT E, communications receivers and test instruments.
