50W CLASS D AUDIO AMPLIFIER EVALUATION BOARD
DESCRIPTION
The ZXCD50STEVAL 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 up to 50W music power into 4 .
INTRODUCTION
The ZXCD50STEVAL is a 50W music power (4
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 25 volts maximum. Voltages in
excess of 25 volts may cause permanent damage to the
board.
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
as well as a mute facility.
