OPA4234U Product Details

OPA4234U Overview


Op amp is packaged in 14-SOIC (0.154, 3.90mm Width) case. General Purpose-type instrumentation amplifiers are used in this application. The case in which buffer amplifier is delivered is called a Tube case. There is a growing number of terminations approaching the number of 14. It consists of a total of 14 pins in total. Please take in mind that op amp should be run at 15V. This particular linear amplifier is a type of Operational Amplifier device, to be precise. 14 pins are available on the instrumentation amplifier. There is an input offset voltage of 250μV for this buffer op amp. For this electrical component, Surface Mount is the recommended mounting type. Regarding the operating temperature of this device, instrumentation amplifier performs well at a temperature of -40°C~85°C . In order for this instrumentation amplifier to operate, the supply current needs to be between 275μA and 10 . Maintain 120dB as the voltage gain. It is possible to count 4 elements on this buffer amplifier. The operating supply voltage of instrumentation amplifier is rated 18V voltage.
