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).
