Summing Two Single-Ended Input Signals
SLOS369F – JULY 2002 – REVISED JULY 2008............................................................................................................................................................... www.ti.com
If summing a ring tone and a phone signal, the phone signal should use a differential input signal while the ring
tone might be limited to a single-ended signal. Phone gain is set at gain 1 = 0.1 V/V, and the ring-tone gain is set
to gain 2 = 2 V/V, the resistor values would be…
R
I1 = 3 M, and = RI2 = 150 k.
The high pass corner frequency of the single-ended input is set by CI2. If the desired corner frequency is less
than 20 Hz.
Figure 36. Application Schematic With TPA2005D1 Summing Differential Input and
Single-Ended Input Signals
Four resistors and three capacitors are needed for summing single-ended input signals. The gain and corner
frequencies (fc1 and fc2) for each input source can be set independently (see equations Equation 11 through
Equation 14, and Figure 37). Resistor, RP, and capacitor, CP, 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.
