Getting Started

To evaluate this part, use a breakout board for the WB SOIC-16 package and ensure 0.1uF bypass capacitors are placed as close to the VDD pins as possible. Standard digital logic signals can be applied to the input pins without special level shifting if within the 3.135V to 3.465V operating range.
