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.

Note2) measuring conditions :
input / output settings after power-down sequence are, PDN pin is at GND level, CLKOUT and SDO output are at high
level ( power supply voltage ) with no external connection, input voltage on those input pins is 1/2 level of power supply
which are set to accept Hi-Z input at power-down, and TEST = ATPG = GND ( or left open ).
Power supplies are AVDD = DVSS = PVDD.
Each ground pin ( DVSS, AVSS, PVSS ) is always 0 V ( voltage reference ).
Note3) Operation at 27 MHz, NTSC mode on-chip 75% color bar output is enabled.
Note4) DAC ON, Video Amp On SAG Compensation On
Note5) DAC ON, Video Amp Off (SAG Compensation Off)
Note6) DAC Off, Video Amp Off (SAG Compensation Off)
