Texas Instruments INA121PG4

INA121PG4 Overview
It is packaged in an PDIP-case that protects the operational amplifiers from damage. An op amp of this type is a INSTRUMENTATION AMPLIFIER-type. It is estimated that there will be at least 8 terminations this year. A total of 8 pins are attached to buffer op amp. As a reminder, this buffer op amp should be powered by 15V battery and that the battery should be inserted in the amplifier. A type of Instrumentation Amplifier op amp ic can be identified by the fact that this is a type of Instrumentation Amplifier device. In total, the buffer amplifier consists of 8 pins. Op amp ic rates 200μV for input offset voltage. A supply current of 450μA can be used to operate this linear amplifier. Maintain 80dB as the voltage gain. There are a total of 1 channels available on the op amps. This instrumentation amplifier cannot operate below -40°C degrees Celsius. You should only use instrumentation amplifier at temperatures that are no higher than 85°C. A voltage rating of 3 is indicated for the op amp's operating supply voltage. It is important to keep in mind that the power supply voltage of this electric component is below 36V, which is suitable. Keeping the linear amplifier's supply voltage above 4.5V is recommended. In order to conduct this part, you will need to provide dual supply voltages of 18V volts. The quiescent current is 450μA. It is important that the linear amplifier resistance stays within the range of 1 TΩ.
