Product Summary
The TPA4411YZHR is a stereo headphone driver designed to allow the removal of the output DC-blocking capacitors for reduced component count and cost. The TPA4411YZHR is ideal for small portable electronics where size and cost are critical design parameters. The TPA4411YZHR is capable of driving 80 mW into a 16-W load at 4.5 V. The device has a fixed gain of –1.5 V/V and headphone outputs that have ±8-kV IEC ESD protection. The TPA4411YZHR has independent shutdown control for the right and left audio channels. Notebook Computers, CD / MP3 Players, Smart Phones, Cellular Phones, PDAs.
