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
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.
They offer 50W and 100W into 4
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.
