The OPA350 series is a rail-to-rail CMOS operational amplifier optimized for low voltage, single-supply operation. It features rail-to-rail input/output, low noise, and high speed operation, making it suitable for driving sampling Analog-to-Digital (A/D) converters, cell phone PA control loops, and video processing.
The OPA350, OPA2350, and OPA4350 are high‑speed, single‑supply, rail‑to‑rail CMOS operational amplifiers optimized for low‑voltage operation. They offer rail‑to‑rail input and output, low noise (5 nV/√Hz), wide bandwidth (38 MHz) and high slew rate (22 V/µs), making them suitable for driving A/D converters, audio, video, and control loops.
These devices are offered in single, dual, and quad configurations with a variety of surface‑mount and through‑hole packages (MSOP‑8, SO‑8, DIP‑8, SSOP‑16, SO‑14). They operate from 2.5 V to 5.5 V supply voltage and survive temperatures from –55 °C to +150 °C. Detailed electrical characteristics, absolute maximum ratings, and mechanical dimensions are provided in the sheet.
