ADCs/DACs - Special Purpose Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number may be marked obsolete in certain distributor inventories. Confirm that the 48-TQFP package dimensions and pinout match the target PCB layout. Ensure compliance with Moisture Sensitivity Level 3 handling procedures during storage and assembly to prevent damage from humidity exposure. Cross-reference the 1.25 V reference voltage requirement with the system design specifications.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a compact solution for triple-channel video DAC functionality is required. It is suitable for designs prioritizing speed over high-resolution precision due to its 8-bit architecture. Consider the 48-TQFP footprint constraints and the need for a stable 3V-3.6V power supply. Evaluate if the 180M sampling rate meets the bandwidth requirements of the intended video application compared to higher-resolution alternatives.
