Datasheet
The MAX3822 evaluation kit (EV kit) is a fully assembled
demonstration board that simplifies evaluation of the
MAX3822 quad limiting amplifier. The EV kit is shipped
from the factory with all components needed to inter-
face with standard 50Ω test equipment. The kit features
on-board power-supply filtering and consumes approxi-
mately 240mA with a +3.3V supply. To facilitate evalua-
tion of the MAX3822 at speed, the EV kit is laid out with
50Ω controlled impedance on all signal lines.
