6 / 8 page ZXCD1210 Issue 2 - October 2007 6 www.zetex.com © Zetex Semiconductors plc 2007 The closed loop Class D architecture maintains high efficiency ensuring cool running in the smallest footprint whilst achieving much reduced output impedance for tight bass control. Additionally the feedback architecture compensates for supply dips and the bridge design accommodates high off load voltages. This means that use of a basic SMPS or an unregulated supply is achievable without compromising performance. The designs feature soft start controls and under voltage lockout controls to maintain anti-pop behavior. Design options include short circuit, thermal and DC offset protection circuits. Volume and phase controls and high/low pass filters are simply added to the input circuitry. The scalable architecture of the ZXCDSUBEV series utilises all N-channel output stage with either bridge tied load (BTL) or single ended (SE) configurations, together with power supply options to generate 150W, 300W or 500W RMS into 4 designs from a single platform. Many more power options readily produced. The ZXCD50STEVAL stereo and ZXCD100MOEVAL mono reference designs have an open loop architecture and feature output stages constructed using Zetex MOSFETs directly driven from the ZXCD modulator device. ZXCD50STEVAL THD+N versus output power They offer 50W and 100W into 4 respectively with typical THD+N of 0.5% and 0.9% up to 90% full power. Careful design has eliminated any potential crossover distortion artifacts. Frequency response is flat to 20kHz in these designs, typical noise floor is -110dB. These designs feature anti- pop and over current protection and operate simply from a single supply rail. Alternative configurations of these designs are possible with multi-channel applications simply created with a master slave arrangement. Single ended operation is possible with the associated performance compromises.
