The SSM2305 is a fully integrated, single-chip, mono Class-D audio amplifier that is designed to maximize performance for mobile phone applications. The application circuit operates from a single 2.5 V to 5.5 V supply and is capable of delivering 2.8 W of continuous output power with less than 10% THD + N driving a 4 Ω load from a single 5.0 V supply.

The LM4667 is a fully integrated 1.3W, single-supply high efficiency (Class D) switching audio amplifier. It features an innovative modulator that eliminates the LC output filter used with typical switching amplifiers.

• The LM4667 processes analog inputs with a delta-sigma modulation technique that lowers output noise and THD when compared to conventional pulse wid…

The TPA3007D1 is a 6.5-W mono bridge-tied load (BTL) class-D audio power amplifier with high efficiency, eliminating the need for heat sinks. The TPA3007D1 can drive 8- speakers with only a ferrite bead filter required to reduce EMI.

This demonstration board is designed to evaluate the performances of TS4999, that is a stereo fully differential Class-D power amplifier.

It can drive up to 1.35 W into a 8 Ω load at 5 V per channel. The device has four different gain settings utilizing two discrete pins, G0 and G1.

The LM48511 integrates a boost converter with a high efficiency Class D audio power amplifier to provide
3W continuous power into an 8Ωspeaker when operating from a 5V power supply. When operating from a 3V to 4V power supply, the LM48511 can be configured to drive 1 to 2.5W into an 8Ω load with less than 1% distortion (THD+N).

The TPA3110D2 evaluation module consists of a single 15-W, Class-D, stereo audio power amplifier complete with a small number of external components mounted on a circuit board that can be used to directly drive a speaker with an external analog audio source as the input. The EVM’s default output filter configuration supports filter-free operation, but can easily be configured to support LC filter…

The MAX98400B evaluation kit (EV kit) configures the
MAX98400B Class D amplifier to drive 2x12W into a pair
of 8I speakers in stereo mode for audio applications.
The EV kit operates from an 8V to 28V DC power supply.
The EV kit has a programmable gain and the jumper settings
default to a +20.1dB gain. The EV kit accepts a pair
