ZXCD1010

The ZXCD1010 provides complete control and modulation functions at the heart of a high efficiency high performance Class D switching audio amplifier solution. In combination with matched output magnetics and Zetex HDMOS MOSFET devices, the ZXCD1010 provides a high performance Class D audio amplifier with all the inherent benefits of Class D.

The ZXCD1010 is an enhanced version of the ZXCD1000. The timing resistor for the oscillator is taken off the chip enabling improved oscillator frequency matching device to device.

The ZXCD1010 solution uses proprietary circuitry and magnetic technology to realise the true benefits of Class D without the traditional drawback of poor distortion performance. The combination of circuit design, magnetic component choice and layout are essential to realising these benefits.
 
The ZXCD1010 reference designs give output powers up to 100W rms with typical open loop (no feedback) distortions of less than 0.2% THD + N over the entire audio frequency range at 90% full output power. This gives an extremely linear system. The addition of a minimum amount of feedback (10dB) further reduces distortion figures to give < 0.1 % THD + N typical at 1kHz.

From an acoustic point of view, even more important than the figures above, the residual distortion is almost totally free of any crossover artifacts. This allows the ZXCD1010 to be used in true hi-fi applications. This lack of crossover distortion, sets the ZXCD1010 solutions quite apart from most other presently available solutions.
