Note 9: Typicals are at T
Note 10: Tested limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
Note 11: Full channel integral non-linearity error is defined as the deviation of the analog value, expressed in LSBs, from the straight line that best fits the actual transfer
function of the AFE.
Note 12: The sensor’s maximum peak differential signal range is defined as the peak sensor output voltage for a white (full scale) image, with respect to the dark reference
level.
Note 13: PGA Gain Error is the maximum difference between the measured gain for any PGA code and the ideal gain calculated using:
Note 14: Full Channel INL and DNL are tested with CDS disabled, negative signal polarity, DOE = 0, and a single OS input with a gain register setting of 1 (000001b) and
an offset register setting of 0 (000000b).
Note 15: The digital supply current (ID) does not include the load, data and switching frequency dependent current required to drive the digital output bus on pins (D7 - D0).
The current required to switch the digital data bus can be calculated from: Isw = 2*Nd*Psw*CL*V
each data bit switching, CL is the capacitive loading on each data pin, V
is 8, Psw is
example, if the capacitive load on each digital output pin (D7 - D0) is 20pF and the period of t
The calculated digital switching current will be drawn through the V
Note 16: All specifications quoted in LSBs are based on 12 bit resolution.
