OP491GSZ Overview
Packaged in a 14-SOIC (0.154, 3.90mm Width) case, the buffer op amp is ready to use. An op amp ic of the General Purpose type. The op amp is delivered to you in a Tube case. 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. A total of 14 pins are present on the instrumentation amplifier. There is an input offset voltage of 700μV for this buffer op amp. The mounting type that is recommended for this electrical part is Surface Mount. In relation to the operating temperature of this buffer op amp, it works well at an average of -40°C~125°C . As long as the supply current of the chip does not exceed 260μA, this op amp ic can operate. 96.9dB should remain the voltage gain. As far as the device is concerned, buffer amplifier has 4 channels. One of the many advantages that this linear amplifier has, among many other things, is the fact that it outputs Rail-to-Rail signals. The operating supply voltage of the buffer op amp is rated at 9V. Currently, linear amplifier is operating with a quiescent current of 200μA.
