The OPA620 is internally compensated for unity-gain stability. This amplifier has a very low offset, fully symmetrical differential input due to its “classical” operational amplifier circuit architecture. Unlike “current-feedback” amplifier designs, the OPA620 may be used in all op amp applications requiring high speed and precision. Low noise and distortion, wide bandwidth, and high linearity make this amplifier suitable for RF and video applications. Short-circuit protection is provided by an internal current-limiting circuit. The OPA620 is available in plastic and ceramic DIP and SO-8 packages. Two temperature ranges are offered: –40°C to +85°C and –55°C to +125°C. +VCC 7 Non-Inverting Input Inverting Input 3 Output Stage Current Mirror CC 6 Output 2 4 –VCC ...
