. High precision operating range provides optimal linearity and dynamic range.
. Standard precision operating range provides maximum dynamic range and reduced linearity.
. High precision operating range provides optimal linearity and dynamic range.
. Standard precision operating range provides maximum dynamic range and reduced linearity.
. The maximum load for an analog output is 50 pF // 100 Kohms. This load maybe with respect to analog ground VMR or AVSS.

Output filter frequency will define
the maximum frequency
Input filter is recommended to be
>30x higher then the max input
frequency, for good distortion
performance

4v p-p Differential input at 660Hz
Filter corner frequency 470KHz
Additional loading causes internal
voltage drops across output stage
and series resistances
The output stage has a small
signal output impedance of approx
10ohm
Output filter corner fc = 470KHz
Applies to Audio frequency range
