INA216 SBOS503C – JUNE 2010 – REVISED NOVEMBER 2011 www.ti.com APPLICATION INFORMATION Basic Connections VCM IN+ Figure 18 shows the basic connections of the INA216. The input pins, IN+ and IN–, should be connected as closely as possible to the shunt resistor to minimize any resistance in series with the shunt resistance.

INA216 SBOS503C – JUNE 2010 – REVISED NOVEMBER 2011 www.ti.com These comments have framed the decision on what the shunt resistor value should be, based on the full-scale value; but many applications require accurate measurements at levels as low as 10% of the full-scale value. At this level, the input offset voltage of the current shunt monitor becomes a larger percentage of the shunt voltage, and thus contributes a larger error to the output.

INA216 SBOS503C – JUNE 2010 – REVISED NOVEMBER 2011 www.ti.com Input Filtering An ideal location where filtering is implemented is at the inputs for a device. Placing an input filter in front of the INA216, though, is not recommended but can be implemented if it is determined to be necessary. This location is not recommended for filtering because adding input filters induces an additional gain error to the device that can easily exceed the device maximum gain error specification of 0.2%.
