LOW-VOLTAGE AUDIO POWER AMPLIFIER

LOW-VOLTAGE

AUDIO POWER AMPLIFIER

Providing a low-cost, compact alternative to discrete transistor

amplifiers, the ULN3718M integrated circuit is ideal for application

as a headphone driver in portable radios, tape players, and other

battery-operated equipment. The low-power audio amplifier’s wide

T frequency response and low noise ensure premium performance.

C The amplifier will operate (at reduced volume) with supply voltages

as low as 1.8 V without a significant increase in distortion. This feature

U allows operation with a 3 V battery supply and minimizes concern

Y about weak batteries. The class-AB audio amplifier has low quiescent

D L current drain for maximum battery life. This device is rated for opera-

tion with supply voltages up to 9 V.

O N The ULN3718M audio amplifier is supplied in an 8-pin mini-DIP

R O plastic package. A copper alloy lead frame gives the amplifier en-

P hanced power dissipation ratings.
