GENERAL DESCRIPTION

APPLICATIONS

The ADCMP551/ADCMP552/ADCMP553 are single supply,

high speed comparators fabricated on Analog Devices’ proprietary

XFCB process. The devices feature a 500 ps propagation delay

with less than 125 ps overdrive dispersion. Overdrive dispersion,

a measure of the difference in propagation delay under differing

overdrive conditions, is a particularly important characteristic

of high speed comparators. A separate programmable hysteresis

pin is available on the ADCMP552.

Automatic test equipment

High speed instrumentation

Scope and logic analyzer front ends

Window comparators

High speed line receivers

Threshold detection

Peak detection

High speed triggers

Patient diagnostics

A differential input stage permits consistent propagation delay

with a common-mode range from –0.2 V to VCCI – 2.0 V. Outputs

are complementary digital signals and are fully compatible with

PECL and 3.3V LVPECL logic families. The outputs provide

sufficient drive current to directly drive transmission lines

terminated in 50 Ω to VCCO − 2 V. A latch input is included

and permits tracking, track-and-hold, or sample-and-hold

modes of operation. The latch input pins contain internal pull-

ups that set the latch in tracking mode when left open.

Disk drive read channel detection

Hand-held test instruments

Zero crossing detectors

Line receivers and signal restoration

Clock drivers

The ADCMP551/ADCMP552/ADCMP553 are specified over

the –40°C to +85°C industrial temperature range. The ADCMP551

is available in a 16-lead QSOP package; the ADCMP552 is available

in a 20-lead QSOP package; and the ADCMP553 is available in

an 8-lead MSOP package.
