The AD8613/AD8617/AD8619 are low cost, low noise CMOS rail-to-rail input/output operational amplifiers. Their features are low supply current, low input voltage and low current noise. The devices are fully specified for operation from a single supply of 1.8 V to 5.0 V or ±0.9 V and ±2.5 V dual supplies. The combination of low noise, very low input bias currents, and low power consumption makes the AD8613/AD8617/AD8619 ideal for use in portable battery-powered instrumentation, multipole filters, current shunt sense, sensors, ADC predrivers, DAC drivers/level shifters, and low power ASIC input or output amplifiers.
The AD8613, AD8617, and AD8619 are low‑cost, micropower, low‑noise CMOS rail‑to‑rail input/output operational amplifiers. They operate from 1.8 V to 5 V single‑supply or 0.9 V to +2.5 V dual‑supply, making them suitable for battery‑powered instrumentation, sensor interfaces, and low‑power ASIC I/O.
These devices are offered in several surface‑mount packages: AD8613 in 5‑lead SC70 and TSOT‑23, AD8617 in 8‑lead MSOP and SOIC, and AD8619 in 14‑lead TSSOP and SOIC. The datasheet provides detailed electrical characteristics, absolute maximum ratings, thermal resistance, and typical performance graphs.
