| Parameter | Value |
|---|---|
| Type | Class D |
| Series | Boomer® |
| Output type | 1-Channel (Mono) |
| Mounting type | Surface Mount |
| Voltage | 3V ~ 5.5V |

| Operating temperature | -40°C ~ 85°C (TA) |
| Package | Tape & Reel (TR); Cut Tape (CT) |
| Features | Depop, Differential Inputs, Short-Circuit and Thermal Protection, Shutdown |
| Case | 24-WFQFN Exposed Pad |
Differential inputs reject ground-loop noise in a mixed-signal system, and the built-in depop circuit suppresses the thump during power-up or shutdown. Short-circuit and thermal protection mean the part survives a miswired speaker terminal or a stalled cooling fan — it shuts down before the die cracks.
The LM48511SQ/NOPB is sourced through independent distribution and quoted to order against an RFQ.
Yes, it is ROHS3 compliant, meaning no restricted hazardous substances above the threshold limits.
The LM48511SQ/NOPB is the lead-free (NOPB) version of LM48511 in the same 24-WQFN package. It is electrically identical and a drop-in replacement for designs that require RoHS compliance.
