AD8123 POWER SUPPLY FILTERING External power supply filtering between the system power supplies and the AD8123 is required in most applications to prevent supply noise from contaminating the received signal as well as to prevent unwanted feedback through the supplies ...
Page 15
INPUT COMMON-MODE RANGE Most applications that use the AD8123 as a receiver use a driver (such as one from the AD8146/AD8147/AD8148 AD8133, or the AD8134) powered from ±5 V supplies. This places the common-mode voltage on the line nominally at ...
