MAX5715 DAC High Impedance Setting Output leakage currents. What is the leakage when the output is set to High - Z?
For HiZ there is a “leakage” current, which would be independent of applied voltage and increases with temperature.
Answer:
This leakage current is not a guaranteed parameter, but is typically:
|
Temp |
Leakage (Hi Z mode) |
|
Cold (-40°C) |
42pA |
|
Room (25°C) |
50pA |
|
Hot (105°C) |
80pA |
|
Hot (125°C) |
900pA |
The capacitance on the dac output is estimated to be ~15pF.
