Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BT' against the official Texas Instruments datasheet to confirm tape-and-reel packaging specifications. Ensure the order matches the exact pinout and thermal characteristics defined for the 48-TQFP package. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and availability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance between 12-bit resolution and 3MSPS throughput is required. Consider the parallel interface requirements and the 48-pin TQFP footprint during PCB layout. Evaluate power supply constraints to ensure compatibility with the specified 2.7V-5.25V digital and 5V analog voltage ranges.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS788x family of low-power SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS7881 and ADS7891 but offers distinct resolution and speed combinations. The IPFBR and IPFBT variants represent different packaging options within the same functional specification.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7881IPFBT: Offers 4MSPS speed with identical 12-bit resolution. ADS7891IPFBT: Provides 14-bit resolution at 3MSPS. ADS7883: Features micropower consumption in a smaller package.
