Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to confirm package type and temperature grade. Ensure the requested part matches the exact datasheet revision required for your design. Cross-reference the manufacturer's official documentation to validate all electrical specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel ADC with GPIO flexibility is required in a compact footprint. Consider the internal 2.5-V reference if minimizing board space is critical, or use an external reference for improved thermal drift performance. Verify that the system voltage requirements align with the specified analog and digital supply ranges.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS7066 family of high-precision SAR ADCs. It shares functional similarities with the ADS7067, which offers a higher sampling speed of 800 kSPS. Both variants utilize the same pinout and feature set, differing primarily in conversion throughput capabilities.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7067 serves as a direct functional substitute within the same family, offering identical pinouts and features at a higher sampling rate of 800 kSPS. Designers requiring increased throughput can transition to this variant without altering the board layout.
