Product Details

This user guide is designed to aid in the evaluation of the AD8411A current-sense amplifier. The AD8411AR-EVALZ and AD8411ARMEVALZ are designed for easy configuration of different modes of operation and allow flexibility with loads. A shunt resistor (R1), with a maximum standard size of 2818, can be soldered to the both boards.

The AD8411AR-EVALZ accommodates the AD8411A in a small outline integrated circuit (SOIC). The AD8411ARM-EVALZ accommodates the AD8411A in a mini small outline package (MSOP). The AD8411AR-EVALZ and AD8411ARM-EVALZ are hereafter referred to as the AD8411A evaluation board in this user guide.

Full specifications on the AD8411A are available in the AD8411A data sheet available from Analog Devices, Inc., and must be consulted with this user guide when using the AD8411A evaluation board.
