Evaluation Kit for the MAX2038 (MAX2038EVKIT) (MAX2038EVKIT)

The MAX2038 evaluation kit (EV kit) simplifies the evaluation of the MAX2038 8-channel variable-gain amplifier (VGA) and programmable octal mixer array. It is fully assembled and tested at the factory. Standard SMB connectors are included on the EV kit's input and output ports to allow quick and easy evaluation on the test bench. The MAX2038 supports 12-bit ADC performance.

This document provides a list of test equipment required to evaluate the device, a straight-forward test procedure to verify functionality, a description of the EV kit circuit, the circuit schematic, a component list for the kit, and artwork for each layer of the PCB.
