The gain and corner frequencies (fc1 and fc2) for each input source can be set independently (see Equation 11 through Equation 14, and Figure 32). 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. 14 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): TPA2036D1 |
