Overview
The TS482IDT, produced by STMicroelectronics, is a dual audio power amplifier designed to drive stereo headsets efficiently. This amplifier operates within a voltage range of 2V to 5.5V, making it versatile for various applications. It can deliver up to 100mW per channel into 16Ω loads with a total harmonic distortion plus noise (THD+N) of 0.1% at 5V. The TS482IDT features high power supply rejection ratio (PSRR) and signal-to-noise ratio (SNR), ensuring high-quality audio output. It is available in SO-8, MiniSO-8, and DFN8 packages, catering to different design requirements.
