Design Requirements

The goal of this application is to select an ADC for ATE applications. Table 8-1 shows the parameters for this design example.

Table 8-1 Design Parameters
PARAMETER VALUE
Sampling rate Up to 2MSPS/channel
Total unadjusted error (TUE) over 25°C ±5°C <0.01% with calibration
Supports external switches or multiplexer Full-scale step settling to 99.99% of full-scale in <1.8μs
