These amplifiers use a patentedtrimming technique that achieves superior precision withoutlaser trimming. All are fully specified to operate from +3V to+5V single supply.The combination of low offsets, low noise, very low input biascurrents, and high speed make these amplifiers useful in a widevariety of applications. Filters, integrators, photo-diodeamplifiers and high impedance sensors all benefit from thecombination of performance features. Audio and other ACapplications benefit from the wide bandwidth and lowdistortion.Applications for these amplifiers include Portable and loop-powered instrumentation, audio amplification for portabledevices, portable phone headsets, bar code scanners, andmulti-pole filters. The ability to swing rail-to-rail at both theinput and output enables designers to buffer CMOS ADCs,DACs, ASICs and other wide output swing devices in singlesupply systems.The AD8615, AD8616 and AD8618 are specified over theextended industrial (-40° to +125°C) temperature range.
