OPA2228UA/2K5 Product Details

OPA2228UA/2K5 Overview


The linear amplifier is packaged in a 8-SOIC (0.154, 3.90mm Width) case. The instrumentation amplifier in this picture is of the General Purpose-type. It comes in a Tape & Reel (TR) case, which protects instrumentation amplifier from damage during delivery. We are approaching the 8h termination of the year. It consists of a total of 8 pins in total. It would be helpful if you could remember that this op amp ic should be powered by an 15V battery. Instrumentation amplifier is a part of Operational Amplifier. 8 pins are included on the operational amplifiers. Op amp ic rates 200μV for input offset voltage. It is recommended that this electronic component be mounted using the Surface Mount mounting type. According to the manufacturer, this buffer op amp works well at -40°C~85°C , which is a good operating temperature. 160dB should remain the voltage gain. There is an operating supply voltage rating of 2 for this operational amplifier, which is rated at the manufacturer. For packing the buffer amplifier, the TR-axis is adopted. For optimal performance, this electrical part should be connected to a supply with a current of 3.7mA.
