CS4350
2.3 DAC Analog Characteristics - Commercial (-CZZ)
Test conditions (unless otherwise specified): VLS = VLC = 3.3 V; T
A
= 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 LSB of triangular PDF dither is added to data
4. R

and C
L
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.
