OPA2228UAE4 Product Details

OPA2228UAE4 Overview


Packaging for the buffer amplifier is in the form of a SOIC case. A OPERATIONAL AMPLIFIER-type buffer amplifier is shown here. There is a Rail/Tube case that is delivered with the instrumentation amplifiers. A total of 8 terminations have been reported in the past few weeks. Buffer amplifier has a total of 8 pins on it. I would like you to keep in mind that this buffer amplifier needs to be run at a voltage of 15V. An 8-pin op amp ic is included in the package. With regards to the offset voltage of the input, buffer amplifier is rated at 200μV. Using a supply current of 3.7mA , this buffer op amp will be able to operate. Keeping the voltage gain at 160dB is the best course of action. This op amp needs to be operated at a temperature of not less than -40°C degrees Celsius in order to function properly. You should not use op amp above 85°C degrees. A total of 2 elements are present in this linear amplifier. The operating supply voltage of the buffer op amp is rated at 18V. This electronic part should be conducted with a dual supply voltage of 18V volts for this part.
