Audio Amplifiers

Audio Amplifiers are active semiconductor components designed to boost low-power audio signals from DACs, CODECs, or preamplifiers to a level sufficient to drive headphones, ear speakers, or high-power loudspeaker drivers without degrading signal quality. Modern audio amplifier designs balance power efficiency and thermal performance with acoustic fidelity, spanning efficient Class-D topologies, low-noise Class-AB linear amplifiers, and specialized Class-H or Class-G architectures.

Key selection parameters include continuous output power (expressed in watts per channel), power supply voltage range, speaker load impedance (typically 4, 8, or 16 ohms), THD+N, and idle current consumption. Features such as integrated pop-and-click suppression, short-circuit protection, thermal shutdown, and configurable digital interfaces are critical for reliable system design.

Octatronics indexes a vast selection of audio amplifier ICs, including ultra-compact headphone drivers for mobile devices, high-power stereo amplifiers for automotive sound systems, and efficient class-D drivers for smart home systems.
