Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Confirm availability through authorized distributors as stock levels fluctuate. Ensure compliance with RoHS directives and humidity sensitivity classifications prior to procurement.

Analog To Digital Converters (ADC) Selection Notes

Select the AD4697BCPZ when space-constrained designs require high channel density without external driver amplifiers. The internal LDO simplifies power management by allowing a single analog supply voltage. Verify that the 500 kSPS throughput meets system bandwidth requirements compared to the faster AD4698 variant.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD4697/AD4698 family of precision SAR ADCs. The AD4697 variant specifically targets applications requiring 500 kSPS performance, while the AD4698 offers 1 MSPS. Both share identical pinouts and feature sets, differing primarily in maximum conversion speed.

Analog To Digital Converters (ADC) Replacement Considerations

The AD4698BCPZ serves as a direct functional replacement offering increased sampling speed. Other ADI SAR ADCs may be considered if channel count or resolution requirements differ.
