ANALOG OUTPUT GAIN CONTROL AND PHASING
The DS-11802 is pin-programmable for gains of 0.5, 1.0 and 2.0.
TABLE 2 details the programming of gain control pins 23 (GC1)
and 24 (GC2). When both pins are left unconnected or open, the
gain of the converter is 2.0. The output signal would be: 2 Vin
sin
θ and 2 Vin cosθ. When GC2 is connected to GND and GC1
is left open, the converter gain is 1.0. When GC1 is connected
to GND and GC2 is left open, the converter gain is 0.5. When
looking at the equivalent gain circuit (see FIGURE 2) the gain of
the converter can be modified by adding a resistor between GC1
or GC2 and GND.

Storage
Users are cautioned against using a large value resistor to
modify the gain, as the temperature coefficient of the exter-
nal resistor will not be matched with the TCR of the internal
resistor. The internal gain resistors have an accuracy of 0.05%.
FIGURE 3 illustrates the output phasing between the reference
voltage Vin and the analog output signals as a function of the
digital angle and the converter gain K (0.5, 1.0, or 2.0).
