MAX1448 Evaluation Kit
General Description
The MAX1448 evaluation kit (EV kit) is a fully assembled
and tested circuit board that contains all the components
necessary to evaluate the performance of the MAX1444,
MAX1446, MAX1448, or MAX1449 10-bit analog-to-digital
converters (ADCs). The MAX1444/MAX1446/MAX1448/
MAX1449 ADCs process differential or single-ended ana-
log inputs. The EV kit allows the user to evaluate the
ADCs with both types of signals from one single-ended
analog signal. The digital output produced by the ADCs
can be easily sampled with a user-provided high-speed
logic analyzer or data-acquisition system. The EV kit
comes with the MAX1448 installed. Order free samples of
the MAX1444EHJ, MAX1446EHJ or MAX1449EHJ to eval-
uate these parts. The EV kit operates from a +3V power
supply. It includes circuitry that generates a clock signal
from an AC signal provided by the user.
