The ZXCD1210 provides complete control and modulation functions at the heart of high efficiency high performance Class D switching audio amplifier solutions. In combination with high performance output stages and open or closed loop architectures, the ZXCD1210 provides a high performance audio amplifier with all the inherent benefits of Class D.The ZXCD1210 solution uses proprietary circuit design to realize the true benefits of Class D without the traditional drawback of poor distortion performance. The combination of reference circuit designs, magnetic component choice and layout are essential to realizing these benefits.The ZXCD1210 reference designs provide output powers up to 500W RMS with typical distortion and noise of less than 0.05% and a dynamic range of 98dB. The closed loop designs ensure a high damping factor and excellent supply rejection. The open loop designs provide high performance in the most economic implementation.The closed loop reference designs include circuits specifically for subwoofer applications featuring a flat frequency response up to 250Hz. The open loop designs give the ZXCD1210 the ability to produce amplifiers with full a 20kHz bandwidth.
