RTQ9128DL-QA 45W, Ultra-Low Noise, High-Efficiency, Digital Input 4-Channel Automotive Audio Amplifier with I2C Diagnostics 1 General Description The RTQ9128DL-QA is an ultra-low output noise, highefficiency, four-channel class-D audio power amplifier. It delivers 4x27W into 4 at 10% THD+N from a 14.4V supply in automotive applications. It can achieve over 87% power efficiency with an output switching frequency of up to 2.1MHz for clarity, which enables a cost-optimized solution in a very small PCB size. Additionally, the RTQ9128DL-QA can be set either above the AM band, which eliminates the AM-band interference and reduces output filter size and cost, or below the AM band to optimize efficiency.
