OP491GS Product Details

OP491GS Overview


A 14-SOIC (0.154, 3.90mm Width) case is used to package the op amp. An op amp ic of the General Purpose type. The op amp is delivered to you in a Tube case. It is estimated that there will be 14 terminations in the next few months. A total of 14 pins are located on this board. It would be helpful if you could remember that this op amp ic should be powered by an 5V battery. There are two types of Operational Amplifier op amps in this case, and this device falls into one of them. 14 pins are available on the instrumentation amplifier. With regards to the offset voltage of the input, buffer amplifier is rated at 80μV. For this electrical component, Surface Mount is the recommended mounting type. With regard to operating temperature, this op amp functions well at -40°C~125°C. An 260μA volt supply current is needed for this linear amplifier to operate. 96.9dB should remain the voltage gain. On this instrumentation amplifier, there are 4 circuits that are connected together. In addition to outputting Rail-to-Rail signals, this op amp ic offers a number of other advantages. The linear amplifier consists of 4 different elements in total.
