5.2 Feedback Resistor Network Design With Practical Application Waveform

The circuit further increases the feedback gain resistor network value 2 times as shown in Table 2. The output transient is implicit due to the level is almost as same as the background noise.

Cons:

where, K = 1.38 × 10 23 J/K is Boltzmann’s constant, T is the absolute temperature (K), and B(Hz) is the bandwidth of the system.

CH1 is input from SOC. CH2 is line driver output. CH3 is (DR_MUTE)? controlled waveform by SOC’s GPIO. CH4 is 3.3V for line driver power.
