Preliminary specification
YUV-to-RGB Digital-to-Analog
Converter (DAC)
SAA7167
Voltage output amplifiers
Before the analog input enters the analog mixers, it passes
through voltage output amplifiers. Level shifters are used
internally to provide an offset of 0.2 V and an amplifier gain
of 2 for analog inputs to match with the output levels from
DACs. After buffering with voltage output amplifiers, the
final RGB outputs can drive a 150
load directly (25
internal resistor, 50
external serial resistor, and 75
load resistor at monitor side (see Fig.9).
The output voltage level of DAC ranges from the lowest
level 0.2 V (zero code) to the highest level 1.82 V (all one
code).
With the digital input YUV video data in accordance with
CCIR-601, the RGB output of 8-bit DAC actually ranges
from the 16th step (black) to the 235th step (white).
Therefore, after the voltage divider with external serial
resistor and monitor load resistor, the output voltage range
to monitor is approximately 0.7 V (peak-to-peak).

S = START condition.
Slave address = 1011 111X; this slave address is identical to the one for the SAA9065; X = R/W control bit:
a) X = 0; order to write.
b) X = 1; order to read (not used for SAA7167).
A = acknowledge; generated by the slave.
Subaddress = subaddress byte.
Data = data byte.
P = STOP condition.
