NOTES
'Best Fit between codes 25 and 230. INL is very layout sensitive.
'Due to linearity mismatch in dual ramps.
'Measured from rising edge of clock to transition of Codes 0 to 255.
= ^{'Minimum pulse width (at 20 MHz) limited by rise time. Pulse width for Code 25 will be greater when CLOCK < 20 MHz.}
'Oulput load 10 pF and 2 mA source/sink.
'Load conditions to test oulput drive capability. Linearity will degrade with either capacitive or current loading. Best linearity obtained driving a single CMOS input.
'All performance specifications valid when supply maintained at +5 V, :t5%.
"Tested from +4.75 V to +5.25 V.
Specification subject to change without notice.
