APA2176A - 270mW Stereo Cap-Free Headphone Driver

Download the APA2176A datasheet PDF. This datasheet also covers the APA2176 variant, as both devices belong to the same 270mw stereo cap-free headphone driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The APA2176/2176A is a stereo, fixed gain, and cap-free headphone driver which is available in TQFN4x4 20-pin, TQFN3x3 16-pin (APA2176A) or TSSOP-16 package.

Dual supply voltage provides higher efficiency and better power ripple rejection.
