Product Details

The MAX17854 evaluation kit (EV kit) is used to demonstrate the features and capabilities of the MAX17854 14-channel high-voltage smart sensor data acquisition interface IC. The EV kit is coupled with a MAX17851 EV kit to establish communication with a host PC. With communication established, control of the MAX17854 EV kit is executed through the EV kit GUI on the host PC. The GUI is Windows XP^®-, Windows Vista^®-, Windows^® 7-, and Windows 10-compatible and is available through your local Maxim Integrated sales office.

Note: References to the MAX17851 in this data sheet pertain equally to the MAX17841B as well.

The MAX17854 EV kit design provides a convenient platform for evaluating the features and functions of the IC, in addition to the IC’s electrical parameters. The EV kit with vertical communication connectors (TXLP_CONN, RXLP_CON, TXUP_CONN, RXUP_CONN) and snap and lock battery pack connector enables the user to quickly build and evaluate a system with up to 32 daisychain devices.
