<!-- Paste General Description -->The RTQ9126DH-QA is an ultra-low output noise, high- efficiency, two-channel class-D audio power amplifier. It delivers 2x75W into 4Ω at 10% THD+N from a 25V 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 RTQ9126DH-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.The RTQ9126DH-QA is fully configurable through the I<sup>2</sup>C bus interface and features comprehensive diagnostics array specially designed for automotive applications.The built-in anti-pop functions can reduce the speaker’s pop noise under all kinds of scenarios. Its built-in protection circuits provide thermal fold-back, over-temperature, overcurrent, overvoltage, and undervoltage protections and report error status.The RTQ9126DH-QA is a 3-wire device that receives all clocks from external sources with standard I2S and TDM (Time-Division Multiplexing) formats. It supports a wide range of input sampling rates from 32kHz to 192kHz. The device is offered in a 64-pin RLQFP package with the exposed thermal pad facing up.The recommended junction temperature range is -40°C to 150°C, and the ambient temperature range is -40°C to 125°C.
