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

L

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.
