Description

The TPA4411 is a stereo headphone driver designed to allow the removal of the output dc-blocking capaci- tors for reduced component count and cost.It is ideal for small portable electronics where size and cost are critical design parameters.

The TPA4411 is capable of driving 80 mW into a 16-W load at 4.5 V. It has a fixed gain of -1.5 V/V and headphone outputs have ±8-kV IEC ESD protection. It has independent shut- down control for the right and left audio channels.

The TPA4411 is available in a 20-pin, 4 mm × 4 mm ThinQFN package.
