9 / 41 page ![]() DS691F1 9 CS4350 DAC ANALOG CHARACTERISTICS - COMMERCIAL (-CZZ) Test conditions (unless otherwise specified): VLS = VLC = 3.3 V; TA = 25° C; Input test signal is a 997 Hz sine wave; Valid with the recommended capacitor values on VD_FILT, VQ, VBIAS (as shown in the typical connection diagram in Figure 10) and output circuits as shown in Figure 17 and Figure 18; Fs = 48 kHz, 96 kHz, and 192 kHz; measurement bandwidth 10 Hz to 20 kHz. Notes: 3. One-half LSB of triangular PDF dither is added to data 4. RL and CL represent the minimum resistance and maximum capacitance required for the CS4350’s in- ternal op-amp to remain stable. See Figure 1 and Figure 2 for more details.
