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.","metaTitle":"LM4666SD/NOPB TI Boomer Class D Amp, 1.2W x 2 @ 8Ω","metaDescription":"Texas Instruments LM4666SD/NOPB Boomer Class D stereo amplifier, 1.2W per channel into 8Ω.
