Analog and digital supplies must be separate and decoupled.
(1) Supply decoupling capacitor must be placed as close as possible to the chip’s pin. Value may need changing depending on the external filter
characteristics.
(2) Capacitor may be replaced when an external filter is used with AC coupling.
(3) Capacitor value may be changed to adjust settling time between DPGA gain changes.
(4) Capacitor value may need changing depending on the high-pass cut-off frequency of the external filter.
