3718LOW-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
Tfrequency response and low noise ensure premium performance.
CThe amplifier will operate (at reduced volume) with supply voltages
as low as 1.8 V without a significant increase in distortion. This feature
Uallows operation with a 3 V battery supply and minimizes concern
Yabout weak batteries. The class-AB audio amplifier has low quiescent
D Lcurrent drain for maximum battery life. This device is rated for opera-
tion with supply voltages up to 9 V.
O NThe ULN3718M audio amplifier is supplied in an 8-pin mini-DIP
R Oplastic package. A copper alloy lead frame gives the amplifier en-
Phanced power dissipation ratings.
