Gain (Note 21)
Note 17. Output voltage is proportional to AVDD voltage.
Note 18. In case of measuring at SPP and SPN pins.
Note 19. Load impedance is total impedance of series resistance (R
Note 20. Maximum voltage is in proportion to both AVDD and external input resistance (Rin). Vin = 0.6 x AVDD x Rin
Note 21. The gain is in inverse proportion to external input resistance.
