STA326VJ

Product Summary

The STA326VJ is an integrated solution of digital audio processing, digital amplifier control, and DDX-Power Output Stage, thereby creating a high-power single-chip DDX® solution comprising of high-quality, high-efficiency, all digital amplification. The STA326VJ can be configured via digital control to operate in several output modes providing up to 2.1 channels of power output to speakers. This device is capable to deliver up to 2x30W + 1x60W in 2.1 mode or 2x60W in stereo mode. The STA326VJ can also be configured as a single paralelled full-bridge capable of high-current operation and 1x120W output.
