Notes:
3. 10 kΩ, 100 pF load.
4. DC current only. If dynamic loading exists, then the voltage reference output must be buffered
or the performance of ADCs and DACs will be degraded.
5. All mixer and output gain tables assume the output level bit, OLB, in indirect register 16 (I16) is set,
wherein the input and output full scale values are equal. When OLB=0, the output value is 3 dB
below the input value, given no gain or attenuation.
