ZXCD100MOEVAL
100W CLASS D AUDIO AMPLIFIER EVALUATION BOARD
DESCRIPTION
The ZXCD100MOEVAL evaluation board is based on
the ZXCD1000 Class D audio amplifier solution from
Zetex. This board allows the user to evaluate the high
fidelity audio performance offered by the Zetex
solution, with an output power upto 100W into 4⍀.
FEATURES
• Class D architecture
• Single power supply
• Output power ( Vsupply = 35V)
INTRODUCTION
The ZXCD100MOEVAL is a 100W RMS (4⍀ Load) high
performance class D amplifier. The circuitry contains
MOSFET devices and should therefore be handled
appropriately.
The board requires a single rail power supply of 13
volts minimum and 35 volts maximum. Voltages in
excess of 35 volts may cause permanent damage to the
board.
100 W into 4⍀
• THD + N <0.8% @ 90% power
• >90% efficiency
• Flat frequency response 20Hz – 20 kHz
• Turn on / turn off pop suppression
• Over current protection
The heart of the solution is the ZXCD1000 class D
controller IC and the user should refer to the ZXCD1000
data sheet for further technical information.
The circuit features pop suppression and over current
protection.
• Noise floor –115dB
Note: The ZXCD100MOEVAL is intended as an
evaluation platform for Zetex Class D solutions. Zetex
accepts no liability for external equipment connected
to the ZXCD100MOEVAL or any other form of
consequential damage or loss.
