Note 15. The Maximum input voltage is in proportion to both AVDD and external input resistance (Rin). Vin = 0.7 x
AVDD x Rin / 33kΩ (typ).
Note 16. The gain is in inverse proportion to external input resistance.
Note 17. The Maximum input voltage is in proportion to AVDD. Vin = 0.7 x AVDD (typ) @ BPLVL = 0dB.
