2 The AD8212 supply current in normal voltage operation (V+ = 7 V to 65 V) is the bias current (IBIAS) added to output current (IOUT). Output current varies upon input

differential voltage and can range from 0 μA to 500 μA. IBIAS in this mode of operation is typically 185 μA and 200 μA maximum. For high voltage operation mode, refer

to the High Voltage Operation Using an External PNP Transistor section.

3 The current of the amplifier into VSENSE (Pin 8) increases when operating in high voltage mode. See the High Voltage Operation Using an External PNP Transistor section

for more information.
