GENERAL DESCRIPTION

The ADCMP580/ADCMP581/ADCMP582 are ultrafast voltage comparators fabricated on the Analog Devices, Inc. proprietary XFCB3 Silicon Germanium (SiGe) bipolar process. The ADCMP580 features CML output drivers, the ADCMP581 features reduced swing ECL (negative ECL) output drivers, and the ADCMP582 features reduced swing PECL (positive ECL) output drivers.
