AD8613:  Low Cost, Micropower Low Noise CMOS Rail-to-Rail Input/Output Operational Amplifier

Product Description

The AD8613/AD8617/AD8619 are single/dual/quad micropower rail-to-rail input and output amplifier that features low offset voltage as well as low input voltage and current noise.

The part is fully specified to operate from 1.8 V to 5.0 V single supply (or ±0.9 V and ±2.5 V dual supply). The combination of low offsets, low noise, very low input bias currents, and low power consumption make the AD8613 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
