DESCRIPTION
The amplifer 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 amplifers are required or a bridge confguration is needed. Four independent amplifers coupled with low quiescent current and very low THD makes this an ideal lowdistortion 4-channel audio amplifer for applications such as laptops and computer speakers.
