ADCs/DACs - Special Purpose Procurement Notes

Verify the manufacturer origin as Burr-Brown or Texas Instruments, given the acquisition history. Confirm the package type is 16-pin DIP and check for any specific suffix variations that may indicate temperature range or lead-free compliance. Ensure the part number matches the exact specification for dual 18-bit DAC functionality.

ADCs/DACs - Special Purpose Selection Notes

Select this component when high-resolution 18-bit audio conversion is required with a serial interface. Consider the 16-pin DIP package for prototyping or legacy board designs. Compare performance metrics such as THD+N and SNR against other 18-bit DACs if alternative packages are needed.

ADCs/DACs - Special Purpose Part Context

The PCM69 series represents Burr-Brown's high-performance audio DAC lineup. The PCM69AU specifically denotes the dual-channel variant in an unheated lead DIP package. This component is part of the broader portfolio of audio converters from Burr-Brown, now under Texas Instruments, known for precision analog signal processing.

ADCs/DACs - Special Purpose Replacement Considerations

Check for direct substitutes like the PCM69AP-J or PCM69AK-J, which offer similar specifications but may differ in package type or temperature rating. Verify pin compatibility and electrical parameters before substitution.
