Product Details

Newer Alternatives:

The AD8613/AD8617/AD8619 are single, dual and quad micropower rail-to-rail input and output amplifiers that feature low supply current, low input voltage, and low current noise.

The parts are fully specified to operate from 1.8 V to 5 V single supply, or ±0.9 V and ±2.5 V dual supply. The combination of low noise, very low input bias currents, and low power consumption make the AD8617/AD8619 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.

The AD8619 is available in 14-lead TSSOP and 14-lead SOIC packages. The AD8619W is qualified for automotive applications and is available in a 14-lead TSSOP.
