INA122U/2K5 Overview

Packaging for the buffer amplifier is in the form of a 8-SOIC (0.154, 3.90mm Width) case. The instrumentation amplifier in this picture is of the Instrumentation-type. The case in which buffer amplifier is delivered is called a Tape & Reel (TR) case. The number of terminations is approaching the 8 mark. In total, there are 8 pins on this op amp ic. As a reminder, this buffer op amp should be powered by 15V battery and that the battery should be inserted in the amplifier. 8 pins are available on the instrumentation amplifier. With regards to the offset voltage of the input, buffer amplifier is rated at 250μV. This electronic component is recommended to be mounted using the mounting type Surface Mount. With regard to operating temperature, op amp ranges -40°C~85°C. You should keep the voltage gain at 80dB for the time being. This op amp contains 1 circuits. There is an operating supply voltage rating of 2 for this operational amplifier, which is rated at the manufacturer. The operating supply voltage of the buffer op amp is rated at 5V. For the packing of the instrumentation amplifier, TR is adopted. 60μA quiescent currents are flowing through buffer op amp. In order for the op amp resistance to remain within the 10GOhm range, the op amp should be tested.
