SBASA73A July 2020 – May 2021 AMC3301-Q1
PRODUCTION DATA
Figure 10-1 shows a layout recommendation with the critical placement of the decoupling capacitors. The same component reference designators are used as in the Section 9 section. Decoupling capacitors are placed as close as possible to the AMC3301-Q1 supply pins. For best performance, place the shunt resistor close to the INP and INN inputs of the AMC3301-Q1 and keep the layout of both connections symmetrical.
To avoid causing errors in the measurement by the input bias currents of the AMC3301-Q1, connect the high-side ground pin (HGND) to the INN-side of the shunt resistor. Use a separate trace in the layout to make this connection to maintain equal currents in the INN and INP traces.
