Shutdown mode cuts quiescent current to near-zero for battery conservation — critical when the amp sits idle most of the time in a portable product. Thermal Protection prevents the die from cooking itself under a sustained overload or poor heatsinking, which is a real risk in a small SOIC package with no external heat spreader. ## Lifecycle and sourcing reality The LM4889MA/NOPB carries an Active lifecycle status with ROHS3 compliance. No NRND or EOL notice is on record.","metaTitle":"LM4889MA/NOPB TI Class AB Audio Amp, 1W Mono 8-SOIC","metaDescription":"Texas Instruments LM4889MA/NOPB Boomer® Class AB audio amplifier, 1W mono output into 8Ω, 2.2V–5.5V supply, industrial temp, active production, ROHS3.","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":"Tube","Features":"Depop, Shutdown, Thermal Protection","Output Type":"1-Channel (Mono)","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.2V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Max Output Power x Channels @ Load":"1W x 1 @ 8Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.78","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.78000","currency":"USD"},{"qty":10,"price":"$1.59700","currency":"USD"},{"qty":25,"price":"$1.50600","currency":"USD"},{"qty":100,"price":"$1.28320","currency":"USD"},{"qty":250,"price":"$1.20492","currency":"USD"},{"qty":500,"price":"$1.05430","currency":"USD"},{"qty":1000,"price":"$0.87357","currency":"USD"},{"qty":2500,"price":"$0.85254","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0b16899d0307cf292e896f65633baff1.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4889MA-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/LM4889MA-NOPB when reusing this data.
