GENERAL DESCRIPTION  
Figure 3. 8-Lead LFCSP_VD  
The AD8613/AD8617/AD8619 are single, dual, and quad micro-  
power, rail-to-rail input and output amplifiers that feature low  
supply current, as well as low input voltage and current noise.

The parts are fully specified to operate from 1.8 V to 5 V single  
supply, or ±±.9 V and ±.5 V dual supply. The combination of low  
noise, very low input bias currents, and low power consumption  
make the AD8613/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.
