OPA4234UA Overview
The linear amplifier is packaged in a 14-SOIC (0.154, 3.90mm Width) case. Buffer amps of this type are called General Purpose-types. A Tube case is used to deliver the buffer op amp. A total of 14 terminations have been reported in the past few weeks. In this case, there are 14 pins on the board. Please take in mind that this instrumentation amplifier should be run at 15V. It should be noted that this type of buffer amplifier is exactly what is known as a Operational Amplifier device. 14 pins are located on the operational amplifiers. The input offset voltage is 250μV. It is recommended that this electronic component be mounted using the Surface Mount mounting type. In terms of operating temperatures, this buffer amplifier works very well at a temperature of around -40°C~85°C . In order for this instrumentation amplifier to operate, the supply current needs to be between 275μA and 10 . Voltage gain should remain at 120dB. As far as the device is concerned, buffer amplifier has 4 channels. The operating supply voltage of instrumentation amplifier is rated 18V voltage.
