NOTES
1
Best Fit between codes 25 and 230. INL is very layout sensitive.
2
Due to linearity mismatch in dual ramps.
3
Measured from rising edge of clock to transition of Codes 0 to 255.
4
Minimum pulse width (at 20 MHz) limited by rise time. Pulse width for Code 25 will be greater when CLOCK < 20 MHz.
5
Output load = 10 pF and 2 mA source/sink.
6
Load conditions to test output drive capability. Linearity will degrade with either capacitive or current loading. Best linearity obtained driving a single CMOS input.
7
All performance specifications valid when supply maintained at +5 V,
±
5%.
8
Tested from +4.75 V to +5.25 V.
Specification subject to change without notice.
