MAX2055 Evaluation Kit
General Description
Features
ꢀ Fully Assembled and Tested
The MAX2055 evaluation kit (EV kit) simplifies the evalu-
ation of the MAX2055 high-linearity, digitally controlled,
variable-gain analog-to-digital converter (ADC)
driver/amplifier (DVGA). The EV kit is fully assembled
and tested at the factory. Standard 50Ω SMA connec-
tors are included on the EV kit for the input and output
to allow quick and easy evaluation on the test bench.
