TPA4411 80mW 无电容立体声耳机驱动器

The TPA4411 and TPA4411M are stereo headphone drivers designed to allowthe 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 capable of driving 80 mW into a 16- load at 4.5 V. Both TPA4411 and TPA4411M have a fixed gain of 1.5 V/V and headphone outputs that have ±8-kV IEC ESD protection. The TPA4411 and TPA4411M have independent shutdown control for the right and left audio channels.

The TPA4411 is available in a 2.18 mm × 2.18 mm WCSP and 4 mm × 4 mm Thin QFN packages. The TPA4411M is available in a 4 mm × 4 mm Thin QFN package
