This is acceptable under many RoHS exemptions (e.g., for spare parts, military, or high-reliability assemblies) but must be verified against the buyer's own compliance policy.","metaTitle":"TI LM4850LDX Boomer Class AB Audio Amp","metaDescription":"Texas Instruments LM4850LDX Boomer Class AB audio amplifier, 1.9W x 1 @ 3Ohm mono channel with stereo headphone output, 2.4-5.5V supply, 14-WSON package.","metaKeywords":null},"attributes":{"series":"Boomer®","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Class AB","Series":"Boomer®","Package":"Bulk","Output Type":"1-Channel (Mono) with Stereo Headphones","Mounting Type":"Surface Mount","Package / Case":"14-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"2.4V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"14-WSON (4x4)","Max Output Power x Channels @ Load":"1.9W x 1 @ 3Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.61","stockQuantity":0,"priceTiers":[{"qty":489,"price":"$0.61000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f551d76ad5ac005a11d7e00efc151774.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output power of the LM4850LDX?","answer":"The mono channel delivers 1.9W into a 3Ω load from a 5V supply.
