These amplifiers use a new, patented trimming technique that achieves superior performance without laser trimming. All are fully specified to operate from 3 V to 5 V single supply. The combination of low offsets, very low input bias currents, and high speed make these amplifiers useful in a wide variety of applications. Filters, integrators, diode amplifiers, shunt current sensors, and high impedance sensors all benefit from the combination of performance features. Audio and other ac applications benefit from the wide bandwidth and low distortion. For the most cost-sensitive applications the D grades offer this ac performance with lower dc precision at a lower price point. Applications for these amplifiers include audio amplification for portable devices, portable phone headsets, bar code scanners, portable instruments, and multipole filters. AD8602 7 OUT B 6 IN B 5 +IN B 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. The AD8601 and AD8602 are specified over the extended industrial (–40°C to +125°C) temperature range. The AD8601, single, is available in the tiny 5-lead SOT-23 package. The AD8602, dual, is available in 8-lead MSOP and narrow SOIC surface-mount packages. SOT and µSOIC versions are available in tape and reel only.
