Test Conditions
DBVDD=3.3V, DCVDD = 3.3V, AVDD=HPVDD=SPKVDD =3.3V, T

Signal to Noise Ratio
(A-weighted)
All THD values are valid for the output power level quoted above – for example, at HPVDD=3.3V and R
–76dB when output power is 10mW. Higher output power is possible, but will result in a deterioration in THD.
