INA143UG4 Product Details

INA143UG4 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 5V. The buffer op amp includes 8 pins. Regarding input offset voltage, op amp rates 500μV. This op amp can operate from a supply current at 950μA. Voltage gain should remain at 20dB. 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 1 elements. 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 950μA. Instrumentation amplifier resistance should remain within the range of 55kOhm.
