INA2143UAG4 Product Details

INA2143UAG4 Overview


Packaged in a D case, the buffer op amp is ready to use. An op amp ic of the OPERATIONAL AMPLIFIER type. There is a growing number of terminations approaching the number of 14. The pins on this board total to 14 in total. I would like to remind you that this buffer op amp should be powered by an 5V battery. I would like to specify that this buffer amplifier belongs to the Operational Amplifier-type of devices. A total of 14 pins are present on the instrumentation amplifier. There is an input offset voltage of 750μV for this buffer op amp. As long as the supply current of the chip does not exceed 950μA, this op amp ic can operate. 20dB should remain the voltage gain. For the buffer op amp to operate properly, it must be above the temperature of -55°C degrees Celsius. No temperature greater than 85°C should be used. The linear amplifier consists of 2 different elements in total. In terms of the supply voltage, this electrical part is capable of operating at low voltage levels of under 36V. A high supply voltage of more than 4.5V is recommended for the instrumentation amplifier's supply voltage. As a rule of thumb, you should conduct this electronic part under a dual voltage supply of 18V volts. Currently, linear amplifier is operating with a quiescent current of 950μA. Instrumentation amplifier resistance should stay within the range of 55kOhm.
