INA155U/2K5 Product Details

INA155U/2K5 Overview


There is a 8-SOIC (0.154, 3.90mm Width) case in which the instrumentation amplifier is packaged. This is a Instrumentation type op amp. As far as the packaging is concerned, buffer op amp is delivered in a Tape & Reel (TR) case. In recent months, the number of terminations has approached 8. Buffer amplifier has a total of 8 pins on it. It would be helpful if you could remember that this op amp ic should be powered by an 5V battery. A total of 8 pins are present on the instrumentation amplifier. With regards to the offset voltage of the input, buffer amplifier is rated at 1mV. This electronic component is recommended to be mounted using the mounting type Surface Mount. In terms of operating temperatures, this buffer amplifier works very well at a temperature of around -55°C~125°C . Maintain 33.98dB as the voltage gain. The buffer amp consists of 1 circuits in total. A benefit of this op amp ic is that it outputs Rail-to-Rail signals, which is one of the many advantages it has to offer. There are 2 elements in this buffer amplifier. The instrumentation amplifier is packed in the form of TR. There is an 1.7mA quiescent current in linear amplifier. Instrumentation amplifier resistance should remain within the range of 10 TΩ.
