Note 14. The Maximum input voltage is in proportion to both AVDD and external input resistance (Rin). Vin = 0.7 x

AVDD x Rin / 33k

Ω (typ).

Note 15. The gain is in inverse proportion to external input resistance.

Note 16. The Maximum input voltage is in proportion to AVDD. Vin = 0.7 x AVDD (typ) @ BPLVL = 0dB.
