APPLICATIONS INFORMATION
Layout Considerations
The following advice should be considered when laying
out a printed circuit board for the LTC4355.
The inputs to the servo amplifi ers, IN1, IN2, and OUT
should be connected as closely as possible to the
MOSFETs’ terminals for good accuracy.
Keep the traces to the MOSFETs wide and short. The PCB
traces associated with the power path through the MOS-
FETs should have low resistance (see Figure 3).
For the DFN package, pin spacing may be a concern at
voltages greater than 30V. Check creepage and clearance
guidelines to determine if this is an issue. Use no-clean
solder to minimize PCB contamination.
