Gain setting
The gain of the TDA7491MV is set by the two inputs, GAIN0 (pin 30) and GAIN1 (pin 31).
Internally, the gain is set by changing the feedback resistors of the amplifier.
Table 8.
Input resistance and capacitance
The input impedance is set by an internal resistor Ri = 60 kΩ (typical). An input capacitor
(Ci) is required to couple the AC input signal.
The equivalent circuit and frequency response of the input components are shown in
