GENERAL DESCRIPTION

The ADCMP551/ADCMP552/ADCMP553 are single supply,

high speed comparators fabricated on Analog Devices’

proprietary XFCB process. The devices feature a 750 ps

propagation delay with less than 150 ps overdrive dispersion.

Dispersion, a measure of the difference in propagation delay

under differing overdrive conditions, is a particularly important

characteristic of high speed comparators. A separate

APPLICATIONS

Automatic test equipment

High speed instrumentation

Scope and logic analyzer front ends

Window comparators

High speed line receivers

programmable hysteresis pin is available on the ADCMP552.

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 are fully compatible

with PECL 10 K and 10 KH 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.
