What are the recommended ADC driver, external reference and reference buffer options?
The AD7961 datasheet recommended ADC drivers are the two single-ended op amps ADA4899-1 and AD4897-1 or differential amplifier ADA4932-1. The low-noise, low-power AD8031 rail-to-rail amplifier is recommended to buffer the external reference and the common-mode (Vcm) output voltage of the AD7961. The recommended low noise, low-drift external precision voltage references for the AD7961 are the ADR4520/ADR4540/ADR4550 and ADR440/ADR444/ADR445.
