TEST CONDITIONS
TA = +25°C, BW = 20kHz, AVDD = 5V, fOUT = 1kHz,
first 19 harmonics removed for SNR calculation,
at 16-bit level
TA = +25°C, at zero-code input, fOUT = 1kHz
TA = +25°C, at mid-code input, 0.1Hz to 10Hz
AVDD = 5.5V
AVDD = 3.6V
External VREF = 2.5V (when internal reference is
disabled), all eight channels active
Grades A/B, AVDD = 2.7V to 5.5V
Grades C/D, AVDD = 5.0V to 5.5V
TA = +25°C; all grades
