Manufacturer:ST Description:Four different schemes are shown in Figures 2, 3, 4, and 5. Note that the values of R1 and R2 in these fig- ures should be kept small to minimize pickup of un- wanted noise and interference. A value of 1 kW is often used, since some microphones require a differ- ential input impedance of this magnitude. Unfortu- nately, one would usually desire a significantly higher common mode input impedance to minimize the common mode degradation caused by unbalanced source impedances. Figure 5 shows a technique which allows higher common mode input impedance while maintaining a lower differential source imped- ance. |
