I'm with albbg. There are no bias capacitors at all. Unfortunately the line stubs intended as RF short have high impedance resonance at other frequencies.
@danadakk The fact that the senseless term "RMS power" is used in an ADI application note doesn't give it more sense. See https://en.m.wikipedia.org/wiki/Audio_power#Continuous_power_and_.22RMS_power.22

Thanks to Easy peasy for the detailed calculation. I would usually answer the...
As explained, exact Irms depend on capacitor values and also transformer impedance (winding resistance and leakage inductance), there are however rules of thumb. Due to the asymmetrical load, the current waveform is near to single wave rectifier. Irms is usually calculated with a form factor of...
I understand 4. so that you can either design a DC coupled amplifier (lower cut-off 0 Hz) or an AC coupled amplifier. As we specify cut-off frequency usually for -3 dB gain drop, the shown transfer function has a lower cut-off of about 1 kHz and doesn't fulfill the spec.
As mentioned in the article, rise time is usually defined as time interval between 10% and 90% level of a rising edge. The parameter is e.g. automatically determined by digital oscilloscopes and can be of course also applied to sine waves, although I doubt that makes sense. The discussed...
Curve selection works for me with arrow-up/arrow-down buttons. As down stops at first (lowest temp) and up at last step (highest temp) you can distinguish it.
AD7606 can sample simultaneously up to 200 kS/s, of course also 100 or 10 kS/s. Just pulse CONVST periodically. A FPGA has nearly unlimited capabilities to utilize this data rate for your control system.
+/- 1 % is perfect for standard UART. Even +/- 3 % can work. Notice that STM32 1 % spec is valid for 25 °C only. Additional frequency error can be caused by applying mechanical forces to the package, e.g. due to PCB warping.
