INA129UA/2K5E4 Product Details

INA129UA/2K5E4 Overview


Packaging for the buffer amplifier is in the form of a 8-SOIC (0.154, 3.90mm Width) case. A Instrumentation-type buffer amplifier is shown here. There is a Tape & Reel (TR) 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 125μV. For this electrical component, the recommended mounting type is Surface Mount, which is the most common. The buffer amplifier functions well at -40°C~125°C as far as operating temperature is concerned. Keeping the voltage gain at 80dB is the best course of action. The buffer amp consists of 1 circuits in total. A total of 3 elements are present in this linear amplifier. As a result, linear amplifier's quiescent current is 700μA. It is recommended to keep the buffer amps resistance within the range of 100GOhm.
