Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix CISQ indicates the commercial extended temperature grade (-40°C to +85°C) against the official datasheet. Confirm the WQFN-60 package dimensions match your PCB footprint requirements. Ensure the serial LVDS output format aligns with your downstream digital processing interface specifications before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel conversion at 80 MSPS with 12-bit resolution is required in a compact form factor. The integrated digital error correction reduces external component count compared to non-corrected architectures. Consider the single-supply operation and low-power shutdown modes if energy efficiency is a primary design constraint for portable applications.
