The parts are 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 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. The AD8613 is available in a 5-lead SC70 package and a 5-lead TSOT-23 package. The AD8617 is available in 8-lead MSOP and 8-lead SOIC packages. The AD8619 is available in 14-lead TSSOP and 14-lead SOIC packages. –IN A +IN A V+ –IN D AD8619 TOP VIEW (Not to Scale) 12 +IN D 11 V– 10 9 8 +IN B –IN B OUT B +IN C –IN C OUT C 05622-035 Figure 4. 14-Lead TSSOP OUT A 1 14 13 OUT D –IN D +IN D –IN A 2 +IN A 3 V+ 4 AD8619 12 TOP VIEW 11 V– (Not to Scale) +IN B 5 10 +IN C –IN B 6 OUT B 7 9 8 –IN C OUT C Figure 5. 14-Lead SOIC_N Rev.
