Frequently Asked Questions
Q1: Are your AD9748ACPZ-RL7 100% original?
A1: All stock is brand new original from ADI. Every reel passes ESD, visual and date code inspection, packed in factory moisture-proof bags.
Q2: What do Z and RL7 suffix mean?
A2: Z = RoHS lead-free green packaging; RL7 stands for 7-inch tape & reel with 1500 pieces per reel for SMT production.
Q3: What’s the advantage of pin compatibility?
A3: This DAC shares identical pin layout with other TxDAC series. You can upgrade between 8/10/14-bit models without redesigning PCB.
Q4: How to layout analog & digital ground for this LFCSP chip?
A4: Separate analog and digital ground loops. Solder the exposed pad fully to ground plane, and route analog traces far from digital lines to reduce noise.
Q5: Can I order small sample quantities?
A5: Yes, we support 1PC minimum order for samples. Contact us via inquiry form for sample pricing.
Q6: How fast is your shipment after payment?
A6: In-stock items will be shipped within 1-2 working days after payment confirmed.
Q7: Do you provide datasheets and CAD files?
A7: We offer official datasheets, 3D STEP models and schematic footprints free upon request.
