DAC ANALOG CHARACTERISTICS - COMMERCIAL (-CQZ)
Test Conditions (unless otherwise specified): VA = VLS = VLC = 5 V; VD = 2.5 V; T
A
= 25°C; Full-scale 997 Hz
input sine wave
; Tested under max ac-load resistance
;
Valid with FILT+ and VQ capacitors as shown in
“Typical Connection Diagram” on page 19
; Measurement Bandwidth 10 Hz to 20 kHz.
Notes:
1.
One-half LSB of triangular PDF dither is added to data.
2.
Performance limited by 16-bit quantization noise.
3.
V
FS
is tested under load R
