AD9696

The AD9696 and AD9698 are ultrafast TTL-compatible voltage 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 devices 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 which are less than 2 mV and offset currents less than 1μA. A latch enable input is provided to allow operation in either 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 qualified versions of the AD9696 come in the TO-100 can and ceramic DIP; the dual AD9698 comes in ceramic DIP.
