RREF1
18
1210 Ohm Current Setting Resistor. Connection point for external current
setting resistor for DAC1. The resistor is connected between
RREF1 and GND. Output video levels are inversely proportional
to the value of RREF1.
RREF2
13
1210 Ohm Current Setting Resistor. Connection point for external current
setting resistor for DAC2. The resistor is connected between
RREF2 and GND. Output video levels are inversely proportional
to the value of RREF2.
RREF3
8
1210 Ohm Current Setting Resistor. Connection point for external current
setting resistor for DAC3. The resistor is connected between
RREF3 and GND. Output video levels are inversely proportional
to the value of RREF3.
RREF4
99
1210 Ohm Current Setting Resistor. Connection point for external current
setting resistor for DAC4. The resistor is connected between
RREF4 and GND. Output video levels are inversely proportional
to the value of RREF4.
VREF
98
1.235 V Voltage Reference Input. External voltage reference input,
internal voltage reference output, nominally 1.235V.
