actual sampling instant. Aperture delay (t AD ) is the time
defined between the falling edge of the sampling clock
and the instant when an actual sample is taken (Figure 4).
Aperture Jitter
Figure 4 depicts the aperture jitter (t AJ ), which is the
sample-to-sample variation in the aperture delay.
Output Noise (n OUT )
The output noise (n OUT ) parameter is similar to the ther-
mal + quantization noise parameter and is an indication
of the ADC’s overall noise performance.
No fundamental input tone is used to test for n OUT ; INP,
INN, and COM are connected together and 1024k data
points collected. n
OUT is computed by taking the RMS
value of the collected data points.
Overdrive Recovery Time
Overdrive recovery time is the time required for the
ADC to recover from an input transient that exceeds the
full-scale limits. The MAX12553 specifies overdrive
recovery time using an input transient that exceeds the
full-scale limits by ±10%.
