RREF1

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

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

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

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

1.235 V

Voltage Reference Input. External voltage reference input,

internal voltage reference output, nominally 1.235V.
