Industrial temperature grade — not just consumer
The exposed pad pulls heat into the PCB copper.
Active lifecycle — no LTB risk on this line
Texas Instruments lists the LM4666SD/NOPB as Active (current production). There is no last-time-buy notice, no NRND flag, and no announced end-of-life. For a BOM freeze or a production ramp, this part is a stable line item. The Boomer® family has broad distribution coverage, so multi-source procurement through independent channels is straightforward — we source and quote against an RFQ with current availability confirmed at quote time.
