OP491GBC Product Details

OP491GBC Overview


The instrumentation amplifier in this picture is of the OPERATIONAL AMPLIFIER-type. During the past two weeks, there have been close to 14 terminations. A total of 14 pins are located on this board. This linear amplifier should be powered by an 5V battery. This particular linear amplifier is a type of Operational Amplifier device, to be precise. You should keep the voltage gain at 96.9dB for the time being. To operate this buffer amplifier, the temperature must not be lower than -40°C. A temperature greater than 125°C should not be used for the operation of buffer amplifier. This electric component can work from a voltage of under 12V as far as supply voltage is concerned. A voltage of 2.7V or higher is recommended for the linear amplifier's supply voltage. This electrical part should be conducted under the dual supply voltage of 6V volts when you conduct this part.
