Measured with AIN = 0 V.
Measured by FFT analysis where fundamental is –3 dBc.
Input slew rate derived from rise time (10 to 90%) of full scale input.
0utputs terminated through 100
Measured from ENCODE in to data out for LSB only.
For full-scale step input, 8-bit accuracy is attained in specified time.
Recovers to 8-bit accuracy in specified time after 150% full-scale input overvoltage.
Output time skew includes high-to-low and low-to-high transitions as well as
