Product details

The Texas Instruments TPA4411YZHT is a Class AB stereo headphone amplifier from the DirectPath series, delivering 100 mW per channel into a 16 Ω load. It operates from a 1.8 V to 4.5 V supply, making it a direct fit for single-cell Li-ion or dual-cell alkaline portable designs. The 16-DSBGA package (2.24 mm × 2.16 mm) keeps the footprint small enough for compact media players, smartphones, and handheld gaming consoles. On-chip depop circuitry eliminates the audible click when the amplifier is enabled or disabled, and the shutdown pin allows the output stage to be disabled when audio is not needed.

Supply and temperature range — what they mean for the BOM

The 1.8 V to 4.5 V supply range covers the full discharge curve of a Li-ion cell with margin on both ends. At the low end, 1.8 V allows operation from two alkaline cells in series.

Frequently asked questions

What is the output power of TPA4411YZHT into 32 ohms?

The datasheet specifies 100 mW per channel into 16 Ω. Output power into 32 Ω will be lower — typically around 50 mW per channel — due to the higher load impedance, but the exact figure depends on supply voltage and THD+N limits.

What is the closest pin-compatible alternative to TPA4411YZHT?

Within the DirectPath family, the TPA4411YZHR uses the same die in a different DSBGA package variant (different ball pitch or marking). For a drop-in replacement, verify the package code suffix — the YZHT is the Tape & Reel ordering code for the 16-DSBGA (2.24x2.16) package.
