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

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.
