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, T
A
= -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
) and output circuits as shown in
; 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
,
, and
more details on the CS4350-DZZ THD+N performance with 0dB input signal.
