OPA381AIDRBTG4 Product Details

OPA381AIDRBTG4 Overview


There is a growing number of terminations approaching the number of 8. The pins on this board total to 8 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 Other Telecom ICs-type of devices. A total of 8 pins are present on the instrumentation amplifier. There is an input offset voltage of 7μV for this buffer op amp. As long as the supply current of the chip does not exceed 800μA, this op amp ic can operate. Keeping the voltage gain at 135dB is the best course of action. As far as the device is concerned, buffer amplifier has 1 channels. For the buffer op amp to operate properly, it must be above the temperature of -40°C degrees Celsius. No temperature greater than 125°C should be used. In terms of the supply voltage, this electrical part is capable of operating at low voltage levels of under 5.5V. A high supply voltage of more than 2.7V is recommended for the instrumentation amplifier's supply voltage. The linear amplifier is equipped with a telecom IC type TELECOM CIRCUIT.
