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

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 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.

FEATURES

50W music into 4

25W music into 8

Note: The ZXCD50STEVAL is intended as an evaluation platform for Zetex

Class D solutions. Zetex accepts no liability for external equipment

connected to the ZXCD500STEVAL or any other form of consequential

damage or loss.
