TDA7492MV
Applications information
Doc ID 16264 Rev 1
21/26
6.3
Gain setting
The gain of the TDA7492MV 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.
6.4
Input resistance and capacitance
The input impedance is set by an internal resistor Ri = 60 k
(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
Figure 24. For Ci = 470 nF the high-pass filter cut-off frequency is below 20 Hz:
fc = 1 / (2 *
π * Ri * Ci)
