Note1) Values are when a 390 ohm output load, a 12k ohm IREF pin resistor and on-chip VREF are used.
Full scale output current is calculated as Iout = full scale output voltage ( typ. 1.28 V ) / 390 ohm = typ. 3.28 mA.
Note2) A voltage referenced to VSS when a decimal zero voltage is input to DAC.
Note3) VOUT Output Level Output Load Resistor: 150ohm, Load Capacitor: 15pF Internal Color Bar output
Note4) Output signal from DAC to which Input data corresponded 1Vpp. This signal is input to AMP.
Load resistor is 150ohm and Load capacitor is 15pF as shown bellow figure at (5) Current Consumption.
