1, 4, 16, 64. RG equals the resistance between the gain sense
lines (Pins 2 and 15) of the AD625. In Figure 38, RG equals
the sum of the two 975 Ω resistors and the 650 Ω resistor, or
2600 Ω. RF equals the resistance between the gain sense and the
gain drive pins (Pins 12 and 15, or Pins 2 and 5), that is RF
equals the 15.6 kΩ resistor plus the 3.9 kΩ resistor, or Figure 39. SPGA with Multiplexer Error Sources
Figure 39 shows a complete SPGA feeding a 12-bit DAS with a
0 V–10 V input range. This configuration was used in the error
budget analysis shown in Table II. The gain used for the RTI
calculations is set at 16. As the gain is changed, the ON resistance of the multiplexer and the feedback resistance will change,
which will slightly alter the values in the table.
Table II. Errors Induced by Multiplexer to The resistor for this calculation is the user-provided feedback resistance (RF).
20 kΩ is recommended value (see Resistor Programmable Gain Amplifier section). 2
The leakage currents (IS and IOUT) will induce an offset voltage, however, the offset
will be determined by the difference between the leakages of each “half’’ of the
differential multiplexer. The differential leakage current is multiplied by the
feedback resistance (see Note 1), to determine offset voltage. Because differential
leakage current is not a parameter specified on multiplexer data sheets, the most
extreme difference (one most positive and one most negative) was used for the
calculations in Table II. Typical performance will be much better.
**The frequency response and settling will be affected by the ON resistance and
internal capacitance of the multiplexer. Figure 40 show
