The For the most cost-sensitive applications, the D grades offer this AD8601, single, is available in a tiny, 5-lead SOT-23 package. The ac performance with lower dc precision at a lower price point. AD8602, dual, is available in 8-lead MSOP and 8-lead, narrow Applications for these amplifiers include audio amplification for SOIC surface-mount packages. The AD8604, quad, is available portable devices, portable phone headsets, bar code scanners, in 14-lead TSSOP, 14-lead SOIC, and 16-lead QSOP packages. portable instruments, cellular PA controls, and multipole filters. See the Ordering Guide for automotive grades. The ability to swing rail-to-rail at both the input and output enables designers to buffer CMOS ADCs, DACs, ASICs, and other wide output swing devices in single-supply systems.
