Voltage Reference
VREF
38
35
+1.235 V
Voltage Reference output/input. An internal voltage
source of +1.235 Volts is output on this pin. An external
+1.235 Volt reference may be applied here which
overrides the internal reference. Decoupling VREF to GND
with a 0.1
F ceramic capacitor is required.
RREF
39
36
560
Current-setting resistor. The full-scale output current of
each D/A converter is determined by the value of the
resistor connected between RREF and GND. The nominal
value for RREF is found from:
RREF = 9.1( VREF/IFS)
where IFS is the full-scale (white) output current (in amps)
from the
D/A converter (without sync). Sync is 0.4 * IFS.
D/A full-scale (white) current may also be calculated from:
IFS = VFS/ RL
Where VFS is the white voltage level and RL is the total
resistive load (in ohms) on each D/A converter. VFS is the
blank to full-scale voltage.
COMP

0.1
F
Compensation capacitor. A 0.1
F ceramic capacitor
must be connected between COMP and VDD to stabilize
internal bias circuitry.
