EVAL-1CH2CHEBZ Evaluation Board
Analog Devices EVAL-1CH2CHEBZ Evaluation Board is designed to support single and dual-channel iCoupler® standard data isolators in 8-lead SOIC packages. The EVAL-1CH2CHEBZ board assesses the entire range of iCoupler data transfer functions. The board also independently powers each side of the iCoupler isolator and applies high differential voltages between the two sides.
