The OPA640 is internally compensated for unity-gain stability. This amplifier has a fully symmetrical differential input due to its “classical” operational amplifier circuit architecture. This allows the OPA640 to be used in all op amp applications requiring high speed and precision. Low noise, wide bandwidth, and high linearity make this amplifier suitable for a variety of RF and video applications. +V S 7, 8 Non-Inverting Input Inverting Input 3 Output Stage 2 Current Mirror CC 6 VOUT 4, 5 –V S International Airport Industrial Park Mailing Address: PO Box 11400, Tucson, AZ 85734 Street Address: 6730 S.
