The RTQ9128-series is an ultra-low output noise, high-efficiency, four-channel class-D audio power amplifier and delivering 4x27W into 4 Ohms at 10% THD+N from a 14.4V supply and 4x45W into 2 Ohms at 10% THD+N from a 14.4V supply in automotive applications. It can deliver over 87% power efficiency, the output switching frequency up to 2.1MHz that enable a cost-optimized solution in a very small PCB size and can be set either above the AM band, which eliminates the AM-band interference and reduces output filter size and cost, or below AM band to optimize efficiency. RTQ9128 is fully configurable through I2C bus interface and intended a full diagnostics array specially intended for automotive applications. The built-in anti-pop functions can reduce the speaker’s pop noise under all kind of scenarios and also built-in protection circuits can provide thermal fold-back, over- temperature, over-current, over-voltage, and under- voltage protections and report error status.
The RTQ9128 is a 3-wired device receiving all clocks from external sources with standard I2S and TDM formats. It can support wide input sampling rate from 32kHz to 96kHz. The IC is offered in a 64 pin LQFP package.
