The LMH6517SQ/NOPB: It integrates two independent VGA circuits in a single 32-WQFN (5x5) package, optimized to drive high-speed ADCs in receiver chains where gain adjustment and signal conditioning are needed before the converter. The part is classified as an ADC Driver, not a general-purpose op-amp, meaning its architecture prioritizes wide bandwidth, low noise, and fast settling for IF sampling and baseband applications in base stations and repeaters.
Package and footprint — what to expect on the board
The 5x5 mm footprint is compact, but the fine-pitch QFN demands careful solder-paste stencil design and reflow profiling.
Lifecycle and compliance — no LTB surprises
The part is ROHS3 compliant, which satisfies EU RoHS requirements and most global environmental regulations. The /NOPB suffix on the order code explicitly indicates lead-free / RoHS compliance, so the marking and finish are consistent with the listing.
Sourcing and procurement posture
For volume production or urgent BOM fills, submit an RFQ; the channel can source from multiple authorized and franchised lines, with lot traceability and date-code consistency checked at the point of receipt. The active lifecycle means the part is widely available through normal distribution, not just surplus channels.
