T_jmax=130^oC
I_leakp < 0.5µA
sampling time is 4 to 24 adc clock cycles of
0.25MHz to 8MHz -> 96µs >= tsample >= 500ns
I_leakn < 0.5µA
920Ω < R_path < 9.9KΩ
(incl parasitics)
C_top
3.7pF < S/H Cap < 6.2pF
(incl parasitics)
C_bottom
connected to low ohmic
supply during sampling
C_top potential just prior to sampling is either
a) ~ last converted channel potential or
b) ground level if S/H discharge feature is enabled.
Complete 10bit conversion takes between 19 and 41 adc clock cycles
Switch resistance depends on input voltage, corner ranges are shown.
Leakage current is guaranteed by specification.
