PRINCIPLES OF OPERATION
analog input, single-ended connection (continued)
The single ended analog input can be dc coupled (Figure 24) as long as the input is within the analog input
common mode voltage range. A capacitor, C, connected from I/Q IN+ to I/Q IN– will help filter any high frequency
noise on the inputs, also improving performance. Note, that the value of capacitor C chosen must take into
account the highest frequency component of the analog input signal.

A single-ended source may give better overall system performance if it is first converted to differential before
driving the THS0842.
