Its supply range of 2.5V to 5.5V means it runs directly from a single lithium-ion cell or a 3.3V/5V rail, simplifying the power tree in battery-powered gear or line-level audio equipment. ## Protection and pop-free shutdown Built-in short-circuit and thermal protection keep the output stage from failing if the headphone jack sees a momentary short or the ambient temperature climbs inside a sealed enclosure. The depop feature suppresses the turn-on/turn-off click that otherwise couples into the headphones — a detail that matters in portable audio where the amplifier powers up on battery insertion. A dedicated shutdown pin lets the system microcontroller cut supply current when the headphones are unplugged, preserving battery life in handheld designs. ## Temperature grade and package fit The 8-SOIC footprint (3.90mm width, 0.154\" pitch) is a standard surface-mount package that reflows on a basic convection profile and fits a two-layer PCB without via fan-out. ## Active production and compliance Fully ROHS3 compliant, with no exemptions that would complicate EU or California market entry.","metaTitle":"TPA6111A2DR Class AB Stereo Headphone Amp, 150mW, 8-SOIC","metaDescription":"Texas Instruments TPA6111A2DR Class AB stereo headphone amplifier, 150mW x 2 into 16Ω, 2.5-5.5V supply, 8-SOIC.
