DAC ANALOG CHARACTERISTICS - COMMERCIAL (-CZZ)
Test conditions (unless otherwise specified): T
A
= 25 °C, VA_H = 9 V, VA = 3.3 V, VD = 3.3 V GND = 0 V; VBIAS+
and VQ capacitors as shown in
; input test signal is a 997 Hz sine wave at 0 dBFS; measure-
ment bandwidth 10 Hz to 20 kHz.
Notes:
1.
One-half LSB of triangular PDF dither is added to data.
