NOTES
1Gain error and gain temperature coefficient are based on the ADC only (with a fixed +2.5 V external reference).
2t
V and tPDF are measured from the threshold crossing of the ENCODE input to valid TTL levels at the digital outputs. The output ac load during test is 5 pF.
3t
CV and tCPD are measured from the threshold crossing of the ENCODE input to valid TTL levels at the digital outputs. The output ac load during test is 20 pF.
4Measured under the following conditions: analog input is –1 dBFS at 19.7 MHz.
5SNR/harmonics based on an analog input voltage of –1.0 dBFS referenced to a 1.024 V full-scale input range.
Typical thermal impedance for the S-100 (MQFP) 100-lead package:
