Product Details

The MAX22502E evaluation kit (EV kit) is a fully assembled and tested PCB that demonstrates the functionality of the MAX22502E and the MAX22503E full-duplex high speed RS-485/RS-422 transceiver. The EV kit includes on-board termination for easy point-to-point evaluation. The EV kit is assembled using MAX22502E in a 12-pin TDFN package, but also provides equivalent functional evaluation for the MAX22503E, which is offered in a 14-pin SOIC package.
