Product Details

TDA7294 100V - 100W DMOS AUDIO AMPLIFIER WITH MUTE/ST-BY

Manufacturer: ST

1. Description

The TDA7294 is a monolithic integrated circuit in Multiwatt15 package, intended for use as audio class AB amplifier in Hi-Fi field applications (Home Stereo, self powered loudspeakers, Topclass TV). Thanks to the wide voltage range and to the high out current capability it is able to supply the highest power into both 4? and 8? loads even in presence of poor supply regulation, with high Supply Voltage Rejection.The built in muting function with turn on delay simplifies the remote operation avoiding switching on-off noises.

2. Features

VERY HIGH OPERATING VOLTAGE RANGE (±40V)

DMOS POWER STAGE

HIGH OUTPUT POWER (UP TO 100W MUSIC POWER)

MUTING/STAND-BY FUNCTIONS

NO SWITCH ON/OFF NOISE

NO BOUCHEROT CELLS

VERY LOW DISTORTION

VERY LOW NOISE

SHORT CIRCUIT PROTECTION

THERMAL SHUTDOWN

3. INTRODUCTION

In consumer electronics, an increasing demand has arisen for very high power monolithic audio amplifiers able to match, with a low cost the performance obtained from the best discrete designs. The task of realizing this linear integrated circuit in conventional bipolar technology is made extremely difficult by the occurence of 2nd breakdown phenomenon. It limits the safe operating area (SOA) of the power devices, and as a consequence, the maximum attainable output power, especially in presence of highly reactive loads.

Moreover, full exploitation of the SOA translates into a substantial increase in circuit and layout complexity due to the need for sophisticated protection circuits.

To overcome these substantial drawbacks, the use of power MOS devices, which are immune from secondary breakdown is highly desirable.

The device described has therefore been developed in a mixed bipolar-MOS high voltage technology called BCD 100.
