OPA2228U/2K5E4 Product Details

OPA2228U/2K5E4 Overview


The linear amplifier is packaged in a SOIC case. This is a OPERATIONAL AMPLIFIER type op amp. The number of terminations approaches 8. Buffer amplifier has a total of 8 pins. Please take in mind that this instrumentation amplifier should be run at 15V. The buffer op amp includes 8 pins. Regarding input offset voltage, op amp rates 5μV. This op amp can operate from a supply current at 3.7mA. The voltage gain should stay at 160dB. The op amp ic has 2 channels on it. The temperature should not be lower than -40°C for operational amplifier ics to operate. Use op amp only at temperatures no higher than 85°C. The operating supply voltage of the buffer op amp is rated at 18V. TAPE AND REEL is adopted to pack the instrumentation amplifier. You should conduct this electronic component under the dual supply voltage of 18V.
