At the low end it still drives headphones down to near-depleted battery voltage — useful for portable speakers, Bluetooth headsets, and handheld gaming audio where every millivolt of headroom extends playtime. ## Lifecycle and sourcing posture The LM4922TL is listed as Active with ROHS3 compliance. No end-of-life notice, no NRND flag — it remains a current-production part that can be specified into new designs without obsolescence risk. Sourced through independent distribution; quoted to order against an RFQ.","metaTitle":"LM4922TL Class AB Stereo Headphone Amp, 80mW, 14-DSBGA","metaDescription":"Texas Instruments LM4922TL Boomer® Class AB stereo headphone amplifier. 80mW per channel into 16Ω, 1.6V–4.2V supply, -40°C to 85°C.

While the rated 80 mW is into 16 Ω, the amplifier will drive 32 Ω headphones at lower power — still sufficient for typical listening levels given headphone sensitivity. The supply voltage range (1.6 V to 4.2 V) provides the voltage swing needed."},{"question":"What is the closest pin-compatible alternative to LM4922TL?","answer":"Within the Boomer® family, several stereo headphone amplifiers share the 14-DSBGA footprint. The LM4922TL's specific combination of 80 mW output and 1.6 V minimum supply is its distinguishing point; a direct pin-compatible substitute would need to match the DSBGA bump map. No single alternative is listed as an official cross, so verify the bump assignment before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4922TL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4922TL when reusing this data.
