The TPA4411 and TPA4411M are stereo headphone drivers designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost. The TPA4411 and TPA4411M are ideal for small portable electronics where size and cost are critical design parameters.
The TPA4411 and TPA4411M are stereo headphone drivers designed for portable electronics where size and cost are critical. They eliminate output DC‑blocking capacitors, provide independent channel shutdown, and include pop‑reduction circuitry.
The devices operate from 1.8 V to 4.5 V, deliver up to 80 mW per channel into a 16 Ω load, and are offered in thin‑QFN (4 mm × 4 mm) and WCSP (2.18 mm × 2.18 mm) packages with PowerPAD™ thermal solutions.
