10 / 41 page 10 DS691F1 CS4350 DAC ANALOG CHARACTERISTICS - AUTOMOTIVE (-DZZ) Test conditions (unless otherwise specified): VLS = 1.35 V to 5.25 V, VLC = 3.14 V to 5.25 V, TA = -40° C to 105° C, input test signal is a 997 Hz sine wave; Valid with the recommended capacitor values on VFILT, 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. Note: 5. One-half LSB of triangular PDF dither is added to data. Also, see Figure 3, Figure 4, and Figure 5 for more details on the CS4350-DZZ THD+N performance with 0dB input signal.
