1. CHARACTERISTICS/SPECIFICATIONS
ANALOG CHARACTERISTICS (TA = 25° C; Logic "1" = VL = 1.8 V; Logic "0" = GND = 0 V;
Full-Scale Output Sine Wave, 997 Hz; MCLK = 12.288 MHz; Measurement Bandwidth 10 Hz to 20 kHz, unless oth-
erwise specified; Fs for Base-rate Mode = 48 kHz, SCLK = 3.072 MHz. Fs for High-Rate Mode = 96 kHz,
SCLK = 6.144 MHz. Test load RL = 10 kΩ, CL = 10 pF (see Figure 17) for line out, RL = 16 Ω, CL = 10 pF (see Fig-
ure 18) for headphone out).
