(Ta = 25°C; AVDD=4.75 ∼ 5.25V; DVDD=3.0 ∼ 3.6V, TVDD=DVDD ∼ 5.25V; Double Speed Mode; DEM = OFF;
SLOW bit = “0”, SDDA bit = “0”)
(Ta = 25°C; AVDD=4.75 ∼ 5.25V; DVDD=3.0 ∼ 3.6V, TVDD=DVDD ∼ 5.25V; Quad Speed Mode; DEM = OFF;
SLOW bit = “0”, SDDA bit = “0”)
Note 18. The passband and stopband frequencies scale with fs. Each response refers to that of 1kHz.
Note 19. Delay time caused by digital filtering. This time is from setting the 16/20/24bit data of both channels to input
