MAX2055 Evaluation Kit
General Description
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.
This data sheet provides a list of equipment required to
evaluate the device, a straightforward test procedure to
verify functionality, a circuit schematic for the kit, a bill
of materials (BOM) for the kit, and artwork for each
layer of the PC board.
