7.13 Typical Characteristics

at T_A = 25°C, AVDD = 3.3 V, IOVDD = 3.3 V, f_IN = 1-kHz sinusoidal signal, f_S = 48 kHz, 32-bit audio data, BCLK = 256 × f_S, TDM slave mode, PLL on, channel gain = 0 dB, and linear phase decimation filter (unless otherwise noted); all performance measurements are done with a 20-kHz, low-pass filter, and an A-weighted filter
