INA122U Overview

A 8-SOIC (0.154, 3.90mm Width) case is used to package the op amp. Instrumentation-type instrumentation amplifiers are used in this application. The case in which buffer amplifier is delivered is called a Tube case. It is estimated that there will be 8 terminations in the next few months. There are a total of 8 pins on this op amp. It is important to remember that this op amp should be operated at a voltage of 15V volts. There are 8 pins on this chip. In terms of the input offset voltage, instrumentation amplifier rates at 250μV. It is recommended that this electronic component be mounted using the Surface Mount mounting type. In terms of operating temperature, this instrumentation amplifier performs well at a temperature of about -40°C~85°C . An 60μA volt supply current is needed for this linear amplifier to operate. There should be no change in the voltage gain. There are 1 channels on the operational amplifiers. There are a total of 2 elements in this linear amplifier. The operating supply voltage of the buffer op amp is rated at 5V. There is a quiescent current of 60μA in this operational amplifier circuit. 10GOhm should be the range of resistance for the linear amplifier.
