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 Cl s amping ection. 4 See Figur and e 19 Figure 2 0 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 Figur . e 9 Rev.
