AD8210
INPUT FILTERING
In typical applications such as motor and solenoid current
sensing, filtering at the input of the AD8210 can be beneficial in
reducing differential noise, as well as transients and current
ripples flowing through the input shunt resistor. An input low-
pass filter can be implemented as shown in Figure 32.

Adding outside components such as R

and C
FILTER
introduces additional errors to the system. To minimize these
errors as much as possible, it is recommended that R
FILTER
be
10 Ω

r lower. By adding the R
FILTER
in series with the 2 kΩ
internal input resistors of the AD8210, a gain error is
introduced. This can be calculated using the following formula:
