| Description | 4-CHANNEL BRIDGE/STEREO AUDIO POWER AMPLIFIER, 12V-18V, 22W, -40 TO 125 DEG C, 20-SOIC |
Product Overview
The TDA8566Q is a high-performance 4-channel audio power amplifier from NXP Semiconductors, designed for automotive and industrial audio applications. This Class AB amplifier supports both bridge-tied load (BTL) and stereo configurations, delivering high-quality audio output with low distortion and high efficiency. Operating over a wide supply voltage range of 12V to 18V, it provides up to 22W per channel (bridge mode) and features built-in thermal shutdown, short-circuit protection, and over-voltage protection for reliable operation in harsh environments. The device offers excellent audio characteristics including low noise, high signal-to-noise ratio, and minimal cross-talk between channels. With a compact 20-SOIC package and extended temperature range (-40°C to +125°C), the TDA8566Q is optimized for automotive infotainment, car audio systems, and industrial audio equipment requiring robust multi-channel amplification.
