General Description

The TPA3126D2 is a 50-W, stereo, low-idle-current Class-D amplifier in a thermally enhanced package.

The TPA3126D2 includes TI's proprietary hybrid modulation scheme, which dynamically reduces idle current at low power levels to extend the battery life of portable audio systems, like bluetooth speakers.

To further simply the design, the Class-D amplifier integrates full protection
