Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix 'CISQ/NOPB' against the manufacturer's current product folder to confirm package type (WQFN), temperature range (-40°C to +85°C), and lead-free status. Ensure compatibility with existing board layouts as the device is pin-compatible with the ADC11C125, ADC12C170, and ADC14155.

Analog To Digital Converters (ADC) Selection Notes

Select this component for high-speed applications requiring wide bandwidth and low power consumption. The separate +1.8V digital supply allows for reduced noise and lower power when interfacing with 1.8V logic. Verify that the system can support the required dual voltage rails and that the exposed pad thermal requirements are met for the WQFN package.
