INA121UA/2K5E4 Product Details

INA121UA/2K5E4 Overview


The linear amplifier is packaged in a SOIC case. This is a INSTRUMENTATION AMPLIFIER type op amp. Linear amplifier is delivered in a Tape and Reel case. 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. To be specific, this instrumentation amplifier is a type of Instrumentation Amplifier. The buffer op amp includes 8 pins. Regarding input offset voltage, op amp rates 300μV. This op amp can operate from a supply current at 450μA. Voltage gain should remain at 80dB. The op amp ic has 1 channels on it. The temperature should not be lower than -40°C for operational amplifier ics to operate. Use op amps only at temperatures no higher than 85°C. This linear amplifier has a total of 3 elements. TR is adopted to pack the instrumentation amplifier. With regard to the supply voltage, this electrical component is capable of working from under 36V. It is advised to keep the op amp's supply voltage higher than 4.5V. You should conduct this electronic component under the dual supply voltage of 18V. Buffer amplifier has a quiescent current of 450μA. Instrumentation amplifier resistance should remain within the range of 1 TΩ.
