NOTES

Ω potentiometer in place of the 15 Ω fixed resistor.

Full scale is defined as 10 volts minus 1 LSB, or 9.961 V.

Ω internal pull-up resistor.

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.
