Please make sure that GND is the first pad to be bonded. Pick-and-place and all component assembly are recommended to be performed in ESD protected area. Note: Pad coordinates are measured from the left bottom corner of the chip to the center of the pads. The coordinates may vary depending on sawing width and location, however, distances between pads are accurate. 3 (6) DA9281.002 10 July 2006 IC OUTLINES VDD OUT MAS9281A1 988um PD Die map reference X2 X1 VSS 850um Note: Die map reference is the actual left bottom corner of the sawn chip.
