The AD8607ARMZ is a low noise precision micropower dual CMOS Operational Amplifier with rail-to-rail input/output. This amplifier uses a patented trimming technique that achieves superior precision without laser trimming. The parts are fully specified to operate from 1.8 to 5.0V. The combination of low offsets, low noise, very low input bias currents and low power consumption makes the AD8607 especially useful in portable and loop-powered instrumentation. 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 low power, single-supply systems.
