The AD8615/AD8616/AD8618 are single/dual/quad, rail-to-rail, input and output, single-supply amplifiers featuring very low offset voltage, wide signal bandwidth, and low input voltage and current noise.
The AD8615, AD8616, and AD8618 are single‑, dual‑, and quad‑channel rail‑to‑rail input and output operational amplifiers that operate from a single 2.7 V to 5 V supply. They offer ultra‑low offset voltage, low noise, low input bias current, and high output drive capability, making them suitable for precision instrumentation, audio, photodiode amplification, and sensor interfaces.
These devices are offered in several surface‑mount packages: the AD8615 in a 5‑lead TSOT‑23, the AD8616 in 8‑lead MSOP and narrow‑SOIC options, and the AD8618 in 14‑lead SOIC and TSSOP packages. They are rated for an industrial temperature range of –40 °C to +125 °C and include ESD protection and detailed absolute‑maximum ratings for reliable operation in demanding environments.
