OPA121KU/2K5G4 Product Details

OPA121KU/2K5G4 Overview


There is a D case package that contains the instrumentation amplifiers. The instrumentation amplifier in this picture is of the OPERATIONAL AMPLIFIER-type. We are approaching the 8h termination of the year. In total, there are 8 pins on this op amp ic. This linear amplifier should be powered by an 15V battery. There are two types of Operational Amplifier op amps in this case, and this device falls into one of them. 8 pins are located on the operational amplifiers. The input offset voltage is 3mV. It is recommended to keep the voltage gain at 114dB at all times. On the buffer amps, there are 1 channels that can be used. For this linear amplifier to work, the temperature should not be below 0°C. In order to avoid damage to the product, operational amplifiers should only be used at temperatures below 70°C. The operating supply voltage of the buffer op amp is rated at 18V. In order for this electronic part to be conducted successfully, you should use a dual supply voltage of 18V.
