7.2.1.2 Detailed Design Procedure

To match the input impedance of the circuit in Figure 7-3 to a specified source resistance, RS, requires that RT || RIN = RS. The equations governing RIN and AV for single-to-differential operation are also provided in Figure 7-3. These equations, along with the source matching condition, must be solved iteratively to achieve the desired gain with the proper input termination. Component values for several common gain configuration in a 50 Ω environment are given in Table 7-1.
