Suffix M indicates that the part is available in Surface Mount package. Suffix X indicates that the part is available in 2.5k units
on Tape and Reel.
*
Current is sampled over a fixed interval. The average current during this interval is indicated by the duty cycle of the PWM output
during next interval.
The Package code M08A is internal to National Semiconductor and indicates an 8-lead surface mount package, SO-8.
