ZHCSM48A December 2020 – April 2021 AMC3306M05
PRODUCTION DATA
The AMC3306M05 requires a single 3.3-V or 5-V supply on its low-side. The high-side supply is internally generated by an integrated DC/DC converter as explained in the Section 7.3.5 section.
The ground reference (HGND) is derived from the terminal of the shunt resistor that is connected to the negative input (INN) of the AMC3306M05. If a four-pin shunt is used, the inputs of the device are connected to the inner leads and HGND is connected to one of the outer leads. To minimize offset and improve accuracy, set the ground connection to a separate trace that connects directly to the shunt resistor rather than shorting HGND to INN directly at the input to the device. See the Section 10 section for more details.
