Voltage Reference
VREF
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 0.1F ceramic capacitor is required.
RREF
36
560
Current-Setting Resistor. Full-scale output current of each D/A
converter is determined by the value of the resistor connected
between RREF and GND. Nominal value of 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
34
0.1 F
Compensation Capacitor. A 0.1 F ceramic capacitor must be
connected between COMP and VDD to stabilize internal bias circuitry.
