NOTES

1Nonlinearity defined as deviation from a straight line from zero to full scale, expressed as a percentage of full scale.

2See Figure 3.

3See Figure 1.

4fMAX expressed in units of MHz.

Specifications subject to change without notice.

Specifications shown in boldface are tested on all production units at

final electrical test. Results from those tests are used to calculate

outgoing quality levels. All min and max specifications are guaranteed,

although only those shown in boldface are tested on all production units.
