ADA4855-3 is a high-performance triple op amp from Analog Devices. It features single supply operation, high speed, and rail-to-rail output.
The ADA4855-3 is a triple, single‑supply operational amplifier from Analog Devices. It offers rail‑to‑rail output swing (0.1 V to 4.9 V), a wide input common‑mode range, and high‑speed performance with a 410 MHz –3 dB bandwidth (G=1) and 870 V/µs slew rate. The device operates from 3 V to 5.5 V supply and includes a power‑down pin that reduces quiescent current to about 1 mA for power‑sensitive applications.
The datasheet provides detailed specifications, pin configurations, typical performance curves, absolute maximum ratings, thermal resistance data, and layout guidelines. It also lists typical applications such as professional and consumer video, imaging, instrumentation, and active filters, and includes an ordering guide for the 16‑lead LFCSP package.
