DRV632
SLOS681B â JANUARY 2011 â REVISED AUGUST 2015
12.1 Layout Guidelines
12.1.1 Gain-Setting Resistors
The gain-setting resistors, RIN and Rfb, must be placed close to pins 13 and 17, respectively, to minimize
capacitive loading on these input pins and to ensure maximum stability of the DRV632. For the recommended
PCB layout, see the DRV632EVM User's Guide.
