Evaluation Kit for the MAX22344/MAX22345/MAX22346

Please check latest availability status for a specific part variant.


The MAX22344–MAX22346 evaluation kits (EV kits) provide a proven design to evaluate the MAX22344–MAX22346, reinforced, four-channel, galvanic digital isolators. Two types of evaluation boards are available to support different channel direction configurations and different ENA polarities of the MAX22344–MAX22346 family. The MAX22345CSEVKIT# is fully assembled and tested, and comes populated with the MAX22345CAAP+. The MAX2234XSEVKIT# is a generic board which has U1 unpopulated allowing the user to select a device from the MAX22344-MAX22346 family. Both evaluation boards support the 20-pin SSOP package type.

The EV kits should be powered from two independent isolated power supplies with nominal output voltage in range from 1.71V to 5.5V. For evaluating the electrical parameters of the device without any isolation between the two sides, a single power supply can also be used.

The MAX2234XSEVKIT# comes with U1 unpopulated and supports the following digital isolators: MAX22344BAAP+, MAX22344CAAP+, MAX22345BAAP+, MAX22345CAAP+, MAX22345RAAP+, MAX22345SAAP+, MAX22346BAAP+, MAX22346CAAP+.
