Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number ADS901E/1KG4 against official Texas Instruments documentation to ensure correct package type and tape-and-reel configuration. Confirm that the 'E' suffix denotes the extended temperature range (-40°C to +85°C) and that the '/1KG4' indicates the specific reel quantity and packaging format. Cross-reference datasheet revisions to ensure compatibility with current design specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 10-bit resolution and 20MHz speed are required within a strict low-power budget. Ensure the system can provide a stable +3V supply within the 2.7V to 3.7V range. Consider the need for an external reference voltage if the adjustable full-scale feature is utilized. Verify that the 28-SSOP package fits the PCB layout constraints and that the single-ended input type matches the signal source requirements.
