NOTES:

2. Temperature Ranges as follows: J, K versions:

0oCto 70oC

TA =25

oC for TYP Specifications. MIN and MAX are measured over the specified operating range.

3. This includes the effect of 5ppm maximum gain TC.

4. Parameter not tested. Parameter guaranteed by design, simulation, or characterization.

5. DB0 - DB11 = 0V to VDD or VDD to 0V.

6. Logic inputs are MOS gates. Typical input current (25oC) is less than 1nA.

7. Typical values are not guaranteed but reflect mean performance specification. Specifications subject to change without notice.
