PCB Layout Guidelines (10)

Efficient PCB layout, especially for the sensing

resistor and output resistor placement, affects

measurement accuracy. For the best results,

refer to Figure 6 and follow the guidelines below:

1. To minimize any resistance in series with

sensing resistor trace, connect the RG1 and

RG2 pins as close as possible to the sensing

resistor.

2. Connect the bypass capacitors close to the

device pins to decouple the power supply

noise.
