Note1) values are when a 390 ohm output load, a 12 Kohm 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) NTSC mode on-chip color bar output is enabled and DAC is “ on “ ( no external output loads are

connected , other than those recommended, connecting-components ).

Note4) 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 = DVCC = PVDD.

Each ground pin ( DVSS, AVSS1, AVSS2, PVSS1, PVSS2 ) is always 0 V ( voltage reference ).

Note5) measuring conditions :

set AVDD = DVCC = 0 V ( potential difference with voltage reference ground is 0 V ) in power-down current 1

condition.Set those input pins to GND level which are set to accept Hi-Z input at power-down.

Power-down current 2 is PVDD power supply current at PVDD = 1.6 V ~ 1.8 V or 2.7 V ~ 3.3 V.

Note6) at RSTN = H, PDN = H

Note7) when DAC output is “ ON “.
