The surface-mount package is suited for automated pick-and-place. No exposed pad is mentioned, so thermal dissipation relies on the board copper and the Class D efficiency.","metaTitle":"LM4949TL/NOPB TI Boomer Class D Audio Amplifier, 2.5W x 2","metaDescription":"LM4949TL/NOPB is a TI Boomer Class D stereo audio amplifier with I²C volume control, 2.5W per channel into 4Ω, 190mW into 16Ω headphones.","metaKeywords":null},"attributes":{"series":"Boomer®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Type":"Class D","Series":"Boomer®","Package":"Bulk","Features":"Depop, Differential Inputs, I²C, Mute, Short-Circuit and Thermal Protection, Shutdown, Volume Control","Output Type":"2-Channel (Stereo) with Stereo Headphones","Mounting Type":"Surface Mount","Package / Case":"25-WFBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"25-µSMD (2.7x2.7)","Max Output Power x Channels @ Load":"2.5W x 2 @ 4Ohm; 190mW x 2 @ 16Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.42","stockQuantity":0,"priceTiers":[{"qty":211,"price":"$1.42000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bbdaa1ad482d833ddc1d09181587df30.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the LM4949TL/NOPB support I2C and differential inputs?","answer":"Yes, the feature set includes I²C control, differential inputs, mute, and volume control."},{"question":"What is LM4949TL/NOPB's listed type (Class D) on this component line?","answer":"The type is Class D, a switching amplifier architecture chosen for high efficiency in portable audio applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4949TL-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4949TL-NOPB when reusing this data.
