When the input to the AFE5801 is AC-coupled with a 0.1muF capacitor and the analog high-pass filter is enabled a ~10db gain is observed for 50kHz input frequencies as shown in figure 19 of the spec sheet. www.ti.com/.../afe5801.pdf The figure also shows that the gain can be removed by enabling the internal digital low pass filter. Do I have to take into account this gain when designing an application? Is the effective maximum rating for 50kHz 10db lower than stated in the spec sheet or can I ignore this internal gain. Thank you!
