The amplifier will operate (at reduced volume) with supply voltages
as low as 1.8 V without a significant increase in distortion. This feature
allows operation with a 3 V battery supply and minimizes concern
about weak batteries. The class-AB audio amplifier has low quiescent
current drain for maximum battery life. This device is rated for opera-
tion with supply voltages up to 9 V.
The ULN3718M audio amplifier is supplied in an 8-pin mini-DIP
plastic package. A copper alloy lead frame gives the amplifier en-
hanced power dissipation ratings.
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鈥檚 wide
frequency response and low noise ensure premium performance.
