LM4702 Overture^®Audio Power Amplifier Series

Stereo High Fidelity 200 Volt* Driver with Mute

General Description

Key Specifications

The LM4702 is a high fidelity audio power amplifier driver

designed for demanding consumer and pro-audio applica-

tions. Amplifier output power may be scaled by changing the

supply voltage and number of output devices. The LM4702

is capable of delivering in excess of 300 watts per channel

single ended into an 8 ohm load in the presence of 10% high

line headroom and 20% supply regulation.

Wide operating voltage range

0.001%

The LM4702 includes thermal shut down circuitry that acti-

vates when the die temperature exceeds 150˚C. The

LM4702’s mute function, when activated, mutes the input

drive signal and forces the amplifier output to a quiescent

state.

Features

n Very high voltage operation

n Scalable output power

n Minimum external components

n External compensation

n Thermal Shutdown and Mute

The LM4702 is available in 3 grades that span a wide range

of applications and performance levels. The LM4702C is

targeted at high volume applications. The LM4702B (in de-

velopment) includes a higher voltage rating along with the

tighter specifications. The LM4702A (in development) is the

premium part with the highest voltage rating, fully specified

with limits over voltage and temperature, and is offered in a

military 883 compliant TO-3 package.

Applications

n AV receivers

n Audiophile power amps

n Pro Audio

n High voltage industrial applications
