... High speed layout practices must be followed to ensure optimum A/D perfor- mance. The AD9022 is built on a trench isolated bipolar process and utilizes an innovative multipass architecture (see the block diagram). The unit is packaged in 28-lead ceramic DIPs and gullwing surface mount packages. The AD9022 is specified to operate over the industrial (– ...

... This T/H saturation precludes clocking the AD9022 in a burst mode. REV. B The duty cycle of the encode clock for the AD9022 is critical for obtaining rated performance of the ADC. Internal pulsewidths within the track-and-hold are established by the encode com- mand pulsewidth; to ensure rated performance, minimum and maximum pulsewidth restrictions should be observed ...
