Procurement Notes

Verify the specific suffix 'T&R' indicates tape and reel packaging when sourcing. Confirm the manufacturer part number matches DS1050U-005+ exactly. Check RoHS compliance documentation provided by Analog Devices. Ensure the distributor source provides valid datasheets for the U-series variant.

Selection Notes

Select this component for applications requiring precise programmable timing or PWM signals at low frequencies. The 8-SOIC package is appropriate for standard surface mount assembly processes. Verify that the 5kHz frequency capability meets the system requirements compared to other variants in the DS1050 family.

Part Context

This part belongs to the DS1050 series of programmable timers and oscillators from Maxim Integrated. It shares functional similarities with other variants like the DS1050Z-005 but differs in package and specific configuration options defined by the suffix. The U-series typically denotes specific package types within the broader product line.

Replacement Considerations

Direct substitutes include other DS1050 variants such as DS1050Z-005+T&R if pin compatibility and package dimensions are verified. Cross-reference electrical specifications carefully before substitution.
