Electrical Characteristics

NOTES:

(1) Low duty cycle pulse testing with Kelvin connections required.

(2) Defined as the input to output differential at which the output drops 100mV below the value measured at a

differential of 1V. Not measurable on 1.5V and 1.8V outputs due to minimum V

(3) Guaranteed by design.
