Grounding

As with any high resolution converter, clean grounding is

important. A low impedance analog ground plane and star

grounding techniques should be used. IOUT2 must be tied

to the star ground with as low a resistance as possible.

When it is not possible to locate star ground close to

IOUT2, 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

ﬂowing to ground. When the resistance of this circuit

board trace becomes greater than 1Ω, a force/sense am-

pliﬁer conﬁguration should be used to drive this pin (see

Figure 2). This preserves the excellent accuracy (1LSB

INL and DNL) of the LTC2753-16.
