The supply range from 1.5 V to 3.6 V means it runs on a single alkaline cell, a Li-ion battery from full charge down to the protection cutoff, or a regulated rail. The -40°C to 85°C temperature grade extends its reach beyond consumer gadgets into outdoor handhelds, automotive cabin modules, and industrial control panels where the ambient can swing. ## Built-in features that save BOM cost The LM4925MM/NOPB integrates Depop circuitry that suppresses the turn-on thump that otherwise needs an external mute relay or series capacitor. Mute and Shutdown pins let a system controller cut the audio path or put the amplifier into a low-power state between use. Thermal Protection shuts down the output stage before the die temperature exceeds the safe limit — important in the 10-VSSOP package where heat sinking is limited. Together these features eliminate several external passives and a protection IC, which simplifies the layout and reduces the component count on a small PCB.","metaTitle":"LM4925MM/NOPB TI Boomer Class AB Audio Amp","metaDescription":"LM4925MM/NOPB from Texas Instruments Boomer series.

The LM4925MM without the suffix is the same die and package but may contain lead in the solder finish. Functionally and pin-compatibly they are identical; choose the /NOPB variant for ROHS-required builds."},{"question":"Can LM4925MM/NOPB be used with a 1.8V supply?","answer":"Yes, the supply range is 1.5V to 3.6V, so a 1.8V rail is well within the operating window.
