Analog Devices Inc. MAX2202X Evaluation Kit
Analog Devices MAX2202X Evaluation Kit provides a demonstration platform for the MAX2202x/F Half-Duplex RS-485/RS-422 Transceivers with AutoDirection. The MAX2202x/F Transceivers provide 3.5kVRMS of digital galvanic isolation between the cable side (RS-485/RS-422 driver/receiver side) and the UART side of the device. These devices feature Analog Devices' proprietary AutoDirection control making them ideal for applications such as isolated RS-485 ports, where the driver input is used in conjunction with the driver-enable signal to drive the differential bus.
The MAX2202X Evaluation Kit features a pre-installed MAX22028 in an 8-pin wide-body SOIC package, but can also be used to evaluate the MAX22025/F, MAX22027/F, and MAX22028F.
