That headphone figure is typical for a Class AB stage — enough for consumer earbuds or monitoring cans, but not for high-impedance studio headphones. If your BOM needs both outputs, this part saves a separate headphone amp IC and the associated PCB area. ## Feature set drives the BOM decision Integrated I²C and SPI control lets the host processor set volume, mute, and bass boost digitally — no external potentiometers. The depop circuit suppresses turn-on/turn-off clicks, and thermal protection shuts down the output stage before the die overheats. For a portable design, these features reduce external passives and simplify the audio subsystem qualification. ## Lifecycle and sourcing posture This part carries an Active lifecycle status — no last-time-buy risk. It is a current-production TI Boomer® device, sourced and quoted to order through independent distribution; availability and pricing confirmed at quote time.","metaTitle":"LM4936MHX/NOPB Boomer® Class AB Audio Amp, 2.2W x 2 @ 3Ω","metaDescription":"LM4936MHX/NOPB is a TI Boomer® Class AB stereo audio power amplifier delivering 2.2W x 2 @ 3Ω speaker + 110mW x 2 @ 32Ω headphone.","metaKeywords":null},"attributes":{"series":"Boomer®","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Type":"Class AB","Series":"Boomer®","Package":"Bulk","Features":"Bass Boost, Depop, I²C, Mute, Shutdown, SPI, Thermal Protection, Volume Control","Output Type":"2-Channel (Stereo) with Stereo Headphones","Mounting Type":"Surface Mount","Package / Case":"28-PowerTSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"28-HTSSOP","Max Output Power x Channels @ Load":"2.2W x 2 @ 3Ohm; 110mW x 2 @ 32Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.71","stockQuantity":0,"priceTiers":[{"qty":111,"price":"$2.71000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9c594a3efcfc9f32a775323cd621dcfc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM4936MHX/NOPB RoHS compliant?","answer":"Yes, the /NOPB suffix indicates lead-free and RoHS-compliant.

The LM4936MHX/NOPB is a Class AB part — lower efficiency but simpler EMI compliance and no output filter. Choose the TPA2012D2 for battery life; choose the LM4936MHX/NOPB for a combined speaker + headphone solution with digital control."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4936MHX-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/LM4936MHX-NOPB when reusing this data.
