The realizable output frequency is
limited to approx <2MHz due to
CAM signal processing which is
based on sampled data
architectures.

c
.
High precision operating range provides optimal linearity and dynamic range.
d
. Standard precision operating range provides maximum dynamic range and reduced linearity.
e
. The maximum load for an analog output is 50 pF // 100 Kohms. This load maybe with respect to analog ground VMR or AVSS.
f
. The maximum load for an analog output is 100 pF // 100 Kohms. This load must be differential and with respect to analog ground(VMR).
