The quad output PA162 com- bines two dual op amp die in a single PSOP pack- age. This approach provides a cost-effective solu- tion to applications where multiple amplifiers are required or a bridge configuration is needed. Four independent amplifiers coupled with low quiescent current and very low THD makes this an ideal low- distortion 4-channel audio amplifier for applications such as laptops and computer speakers. The quad output PA162DK is available in a surface mount 20-pin PSOP, JEDEC MO-166-AB package. Built-in thermal shutdown allows the devices to self- protect against thermal overloads. Care must be ex- ercised to observe the Safe Operating Area (SOA) curve and proper heatsinking will ensure maximum reliability. The wide common mode input range includes the negative rail, facilitating single supply applications. This makes it possible to have a ground-based input driving a single supply amplifier with ground acting as the second or bottom supply of the amplifier.
