PA162DK - Power Operational Amplifier, 40V, 1A
The amplifier design is a dual power op amp on a single monolithic die. The quad output PA162 combines two dual op amp die in a single PSOP package.
This approach provides a cost-effective solution 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 lowdistortion 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 selfprotect against thermal overloads. Care must be exercised 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.
