CS4349
DAC ANALOG CHARACTERISTICS - COMMERCIAL (-CZZ)
Test conditions (unless otherwise specified): VLS = VLC = 3.3 V; T = 25° C; input test signal is a 997 Hz sine
A
wave; Valid with the recommended capacitor values on VFILT, VQ, and VBIAS and output circuit as shown in the typical con-
nection diagram in Figure 10 and Figure 17; Fs = 48 kHz, 96 kHz, and 192 kHz; measurement bandwidth 10 Hz to
20 kHz.
