Short-circuit protection and thermal shutdown are on-die — no external comparator or reset supervisor. The shutdown pin lets a GPIO or power-management IC kill the amp when the system goes to sleep, cutting quiescent draw to near zero. Differential inputs reject ground noise picked up on long input traces, which matters when the audio source is a codec or Bluetooth module on the same board. ## Industrial temperature range, active lifecycle Rated -40°C to 85°C ambient, so it fits outdoor IoT audio nodes, automotive cabin infotainment, and industrial panel annunciators. The /NOPB suffix confirms RoHS3 compliance (lead-free, no added halogens). Lifecycle status is Active; no NRND or EOL notice on record. That means it's still a valid choice for new designs and production BOMs. ## Sourcing and fit for the BOM This part is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time. For a BOM line that needs a compact, efficient mono amp with industrial temperature range and built-in protection, the LM48310SD/NOPB covers it without external glue.","metaTitle":"LM48310SD/NOPB Class D Mono Amp, 2.6W into 4Ω, 10-SON","metaDescription":"TI LM48310SD/NOPB Class D audio amplifier, mono 2.6W into 4Ω, 2.4-5.5V supply, -40 to 85°C, 10-SON package.
