ADL5561ACPZ-R7 identifies a specific Analog Devices differential amplifier ordering option. A useful purchasing record connects that complete code to the released bill of materials, package drawing and required delivery format. This guide explains how to prepare that record, read the manufacturer’s ordering table and resolve documentation questions before an order is released.
Start with the exact ordering row
The ADL5561 datasheet, Rev. G, page 21 lists the following details for ADL5561ACPZ-R7:
| Package | 16-lead LFCSP, 3 × 3 mm body, exposed pad |
|---|---|
| Package option | CP-16-27 |
| Temperature range | −40°C to +85°C |
| Manufacturer packing | 7-inch tape and reel; ordering quantity 1,500 |
| Device branding | Q1P |
The ordering-guide footnote identifies Z as a RoHS-compliant part. The R7 row describes a packing option, so it should not be interpreted as an electrical performance grade. Its listed reel quantity also does not establish a distributor’s minimum order or the packing offered for a smaller quantity.
Keep the RFQ line separate from the packing request
Write ADL5561ACPZ-R7 in the manufacturer part-number field without shortening it to ADL5561. Then state the quantity and the packing you can accept. If a quotation offers cut tape, a partial reel or repacked material, ask for that condition to appear explicitly in the quotation and purchase order. Do not let a packing description silently replace the approved ordering code.
For automated assembly, send the proposed packing details to the assembler before accepting them. Ask about feeder suitability, orientation, leader requirements and the way individual lots will remain identifiable. These are order-specific acceptance questions; the ordering table alone cannot answer them for material that has been divided or repacked.
The same datasheet lists ADL5561ACPZ-WP in waffle-pack format. A supplier proposal using that suffix should therefore be reviewed as an explicit ordering change. Record the disposition with the buyer and assembler rather than deleting the suffix from both records and treating the difference as resolved.
Use the document’s revision history
Rev. G’s own revision history dates the F-to-G update to September 2017 and records the change from package option CP-16-2 to CP-16-27. Use the revision history printed in the PDF to identify the applicable edition. A document revision date does not establish the first release date of a particular ordering code.
For a purchasing file, save the document revision and access date with the approved drawing reference. If a supplier submits an older drawing, ask engineering to compare it with the released footprint and manufacturing instructions. A newer PDF date does not mean that every older lot is unacceptable; the decision needs the actual lot information and the applicable change notices.
Review package changes against the lot offered
ADI PCN 14_0038, published February 13, 2014, includes ADL5561ACPZ-R7 in its affected-model appendix. It describes a change from punched to sawn LFCSP outlines and an assembly-site transfer, with May 14, 2014 as the earliest effective date. ADI states that the lead footprint remains the same.
Use that notice to frame a specific question about offered material. Ask which manufacturer documentation supports its package appearance and lot identification. Keep the response with the quotation. Do not infer an individual unit’s manufacturing date, assembly location or acceptance status from the notice’s effectivity date alone.
If an incoming package differs from a previously approved sample, document the difference and hold the disposition for the responsible quality or engineering team. A documented manufacturing change can explain a difference, but visual resemblance to a drawing or a familiar marking is not proof of authenticity or electrical conformance.
Attach engineering requirements without turning them into supply claims
ADI identifies the ADL5561 as an RF/IF differential amplifier used for ADC driving, single-ended-to-differential conversion and SAW-filter interfaces. Its supply range is 3.0–3.6 V. These facts help route a request to the right technical reviewer; they do not establish that it meets the requirements of a particular converter board.
Keep application acceptance criteria with the engineering record: intended operating conditions, interface requirements and any approved deviation process. For gain connections, common-mode bias and converter-interface calculations, see the separate ADL5561ACPZ-R7 ADC-driver design guide. Ask engineering to approve any proposed replacement against that circuit before purchasing changes the part number.
Build a receiving record before releasing the order
- Agree the complete manufacturer part number, quantity and permitted packing condition.
- Specify required manufacturer or supplier documents, traceability fields and any lot restrictions before quotation acceptance.
- State whether split lots, repacking or ordering-code changes require written approval.
- At receipt, reconcile the purchase order, packing labels, quantity and supplied documentation; route discrepancies for a recorded disposition.
- If testing is required, define its scope, acceptance criteria and reporting requirements with the responsible technical team. Documentation review and visual checks do not establish broadband amplifier performance.
Send the complete ordering code, quantity, required delivery date and agreed documentation or packing requirements through the WWDParts RFQ page. Request written confirmation of price, availability, delivery terms and any order-specific services before placing an order.
