The 2-channel stereo output with dedicated stereo headphone drive covers both speaker and headphone paths from a single 30-ball DSBGA package. Operating across -40°C to 85°C ambient, the part is suited for portable and consumer audio products that must hold performance through temperature extremes — the DSBGA package keeps the footprint small for space-constrained PCBs. ## Active production, ROHS3 compliant The part is ROHS3 compliant, covering the current EU exemption-free material restriction. Sourced to order against BOM quantities; availability and current pricing confirmed at the time of RFQ through independent distribution channels.","metaTitle":"LM4859TL/NOPB Texas Instruments Boomer Class AB, 1.6W x 2","metaDescription":"Texas Instruments LM4859TL/NOPB Class AB audio amplifier, 2-channel stereo with headphone output, 1.6W x 2 @ 4Ohm, 30-DSBGA, active production, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"Boomer®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Type":"Class AB","Series":"Boomer®","Package":"Bulk","Output Type":"2-Channel (Stereo) with Stereo Headphones","Mounting Type":"Surface Mount","Package / Case":"30-WFBGA, DSBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"30-DSBGA","Max Output Power x Channels @ Load":"1.6W x 2 @ 4Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.62","stockQuantity":0,"priceTiers":[{"qty":185,"price":"$1.62000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8697a8c1e75a4da54caeee4d2969b439.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the LM4859TL/NOPB's output power and load rating?","answer":"It delivers 1.6W per channel into 4Ω loads (max output power x channels @ load: 1.6W x 2 @ 4Ohm).
