What are the recommended ADC driver, external reference and reference buffer
The ADAS3022 datasheet recommends the ADA4841 and AD8031 as ADC driver (to
drive auxiliary input pair - AUX±) and reference buffer, respectively. Other
choices include ADA4897, AD8021/22, ADA4899, AD8605/15/55, etc. The recommended
low-drift external references are ADR4540, ADR434, and ADR444.
