2 Refer to Figure 8 for further information on the input bias current. This current varies based on the input common-mode voltage. Additionally, the input bias current
flowing to the +IN pin is also the supply current to the internal LDO.
3 The differential input voltage is specified as 83 mV maximum because the output is internally clamped to 5.6 V. See the Output Clamping section.
4 See Figure 19 and Figure 20 for further information on the output range of the AD8219 with various loads. The AD8219 output clamps to a maximum voltage of 5.6 V
when the voltage at Pin +IN is greater than 5.6 V. When the voltage at +IN is less than 5.6 V, the output reaches a maximum value of (VS − 100 mV).
5 VS (Pin 2) can be connected to a separate supply ranging from 4 V to 80 V, or it can be connected to the positive input pin (+IN) of the AD8219. In this mode, the
current drawn varies with increasing voltage. See Figure 9.
