OP291GS Overview


A 8-SOIC (0.154, 3.90mm Width) case is used to package the op amp. Buffer amps of this type are called General Purpose-types. In the case of Tube cases, linear amplifier will be delivered. During the past two weeks, there have been close to 8 terminations. There are a total of 8 pins on this op amp. It is important to remember that this op amp should be operated at a voltage of 5V volts. In more specific terms, this linear amplifier can be categoriOperational Amplifiered as a Operational Amplifier-type device. A total of 8 pins are present on the instrumentation amplifier. With regards to the offset voltage of the input, buffer amplifier is rated at 700μV. This electronic component is recommended to be mounted using the mounting type Surface Mount. The buffer amplifier functions well at -40°C~125°C as far as operating temperature is concerned. As long as the supply current of the chip does not exceed 840μA, this op amp ic can operate. You should keep the voltage gain at 96.9dB for the time being. 2 channels are available on the instrumentation amplifier. Buffer amplifier produces Rail-to-Rail signals, which is one of its many benefits. The operating supply voltage of the buffer op amp is rated at 9V. Currently, linear amplifier is operating with a quiescent current of 420μA.
