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.
