1) Which is the maximum output current available in voltage mode (0-5V olutput)
2) Which is the maximum current absorption from power supply when I put Vcc =


1)The voltage output should be loaded by a high impedance only, that means no
current should be taken from the Vout pin. There is an internal approximately
1.25kohm resistor generating the voltage drop and therefore the voltage output
will behave as if it had approximately 1.25kohm output impedance.

2)The quiescent current probably change only little with the Vcc voltage,
therefore the only max value that should be considered is the datasheet 5.5mA.
