APPLICATIONS INFORMATION
Grounding
As with any high resolution converter, clean grounding is
important. A low impedance analog ground plane and star
grounding techniques should be used. I
to the star ground with as low a resistance as possible.
When it is not possible to locate star ground close to

OUT2
, a low resistance trace should be used to route this

pin to star ground. This minimizes the voltage drop from
this pin to ground caused by the code dependent current
fl owing to ground. When the resistance of this circuit
board trace becomes greater than 1Ω, a force/sense am-
plifi er confi guration should be used to drive this pin (see
Figure 2). This preserves the excellent accuracy (1LSB
INL and DNL) of the LTC2753-16.
