ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'PZ' against the manufacturer's ordering guide to confirm Pb-free status and package type. Confirm that the 'B' version accuracy rating matches the design requirements for relative accuracy. Check current availability as this component may be subject to lifecycle changes.

ADCs/DACs - Special Purpose Selection Notes

Select the AD7891BPZ-2 for applications requiring ±0.75 LSB relative accuracy. Ensure the analog input voltage stays within the specified range for the -2 model (0 V to +2.5 V, 0 V to +5 V, or ±2.5 V). Verify that the required sample rate does not exceed 500 kSPS per channel in parallel mode.

ADCs/DACs - Special Purpose Part Context

The AD7891 series includes variants with different accuracy grades (A, B, Y) and temperature ranges. The 'B' version provides tighter linearity specifications compared to the 'A' version. The 'Z' suffix indicates a lead-free compliant manufacturing process. The 'P' designation refers to the Plastic Leaded Chip Carrier (PLCC) package.
