Monolithic Power SystemsMP7758 Audio Amplifiers are inductor less, fixed frequency, analog input Class-D audio amplifiers that drives power stereo speakers in a bridge-tied load configuration. These amplifiers are completely integrated thus reducing the solution size. The MP7758 audio...

Maxim Integrated MAX98361 Plug-and-Play Digital Class-D Amplifiers are easy-to-use, low-cost, digital pulse-code modulation (PCM) input amplifiers featuring industry-leading, Class-AB audio performance with Class-D efficiency. The MAX98361 has a digital audio interface that...

This is a Class-D Stereo audio amplifier project that provides 10W stereo output. The amplifier includes Gain control using 2 x Jumpers, Mute function, and shutdown function. RCA female connectors are provided for the audio source input, screw terminals are provided for an easy...

Class D audio amplifiers provide a dual benefit for battery-powered portable devices (Figure 1). They enhance battery life, and they produce much less power dissipation than do their linear cousins. Those features make Class D amplifiers ideal candidates for controlling speed and...

The project described here is a high-efficiency dual BTL class-D audio amplifier with single supply operations. The project was built using TDA7491LP13TR from ST. The low profile PCB design can fit in a small area, operating power supply 9-12V DC, Project supports single-ended or...

The EVAL_AUDAMP24 e-mode GaN HEMT-based evaluation board from Infineon Technologies is a 2-channel, 225W/ch (4Ω at ±43V) or 250 W/ch (8Ω at ±63V) half-bridge class D audio power amplifier for high-end Hi-Fi audio systems. This evaluation board demonstrates how to use the IGT40R070D1...

This low cost low voltage 3W class-D stereo amplifier is based on PAM8403 IC, The PAM8403 is a 3W, class-D audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction. The new filter-less architecture allows the device to drive the speaker directly,...

Clemens Valens @ elektormagazine.com discuss about LTC3623 switching regulator which can be used as Class-D Audio Amplifier. Sure thing, Elektor has published several designs of adjustable power supplies based on switching regulators, so we know that doing this properly in a...
