These amplifiers TOP VIEW 4 13 V+ V (Not to Scale) use a new, patented trimming technique that achieves superior 5 12 +IN B +IN C performance without laser trimming. All are fully specified to 6 11 IN B IN C operate on a 3 V to 5 V single supply. OUT B 7 10 OUT C The combination of low offsets, very low input bias currents, 8 9 NC NC and high speed make these amplifiers useful in a wide variety NC = NO CONNECT of applications. Filters, integrators, diode amplifiers, shunt Figure 4. 16-Lead Shrink Small Outline QSOP (RQ Suffix) current sensors, and high impedance sensors all benefit from the combination of performance features. Audio and other ac The AD8601, AD8602, and AD8604 are specified over the applications benefit from the wide bandwidth and low distortion. extended industrial (40C to +125C) temperature range. 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 SOIC surface-mount packages. The AD8604, quad, is available Applications for these amplifiers include audio amplification for in 14-lead TSSOP, 14-lead SOIC, and 16-lead QSOP packages. portable devices, portable phone headsets, bar code scanners, See the Ordering Guide for automotive grades. portable instruments, cellular PA controls, and multipole filters. 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. Rev.Rev.
