产品详情

The EV-AD74414H-ARDZ is a fully-featured evaluation board that a user can use to evaluate the features of the AD74414H as a full system solution. Power is provided by the MAX17691B isolated flyback solution. Digital channels isolation utilizes the ADuM341E and ADuM342E isolators.

The AD74414H is a quad-channel, software configurable, and input and output device. The device has functionality for current input/output and digital input/output measurements integrated into a single-chip solution with a compatible serial-peripheral interface (SPI).

A user can control the EV-AD74414H-ARDZ by a system demonstration platform (SDP) board. The EVAL-SDP-CK1Z (SDP-K1) board allows the EV-AD74414H-ARDZ to be controlled by the USB port of a PC using the AD74414H ACE Software. The EVAD74414H- ARDZ requires an operating supply of 24V. The PC provides power to the EVAL-SDP-CK1Z (SDP-K1) board.

Full specifications on the AD74414H, MAX17691B, ADuM341E, and ADuM342E are available in the corresponding data sheets available from Analog Devices, Inc., and must be consulted with this user guide when using the EV-AD74414H-ARDZ board.
