Summing Two Single-Ended Input Signals
Four resistors and three capacitors are needed for summing single-ended input signals. The gain and corner
frequencies (f
c1
and f
c2
) for each input source can be set independently (see equations (9) through (12), and
Figure 32). Resistor, R
P
, and capacitor, C
P
, are needed on the IN+ terminal to match the impedance on the IN
terminal. The single-ended inputs must be driven by low impedance sources even if one of the inputs is not
outputting an ac signal.
