... The ADCMP561/ADCMP562 comparators are very high speed devices. Consequently, high speed design techniques must be employed to achieve the best performance. The most critical aspect of any ADCMP561/ADCMP562 design is the use of a low impedance ground plane. A ground plane, as part of a multilayer board, is recommended for proper high speed performance ...

... ATE, bench instruments, and nuclear instrumentation. Overdrive dispersion is defined as the variation in propagation delay as the input overdrive condi- tions are changed (Figure 5). For the ADCMP561/ADCMP562, overdrive dispersion is typically 100 ps as the overdrive is changed from 100 This specification applies for both ...
