TPA2000D2 Datasheet 2-w Filterless Stereo Class-d Audio Power Amplifier

Manufacturer: Texas Instruments

Overview: TPA2000D2 www.ti.com SLOS291F – MARCH 2000 – REVISED MARCH 2007 2-W FILTERLESS STEREO CLASS-D AUDIO POWER.

General Description

The TPA2000D2 is the third generation 5-V class-D amplifier from Texas Instruments.

Improvements to previous generation devices include: lower supply current, lower noise floor, better efficiency, four different gain settings, smaller packaging, and fewer external components.

The most significant advancement with this device is its modulation scheme that allows the amplifier to operate without the output filter.
