KA224A Product Details

KA224A Overview


In order to protect the op amps, a DIP case is used. There are two types of operational amplifiers in this circuit. In recent months, the number of terminations has approached 14. It consists of a total of 14 pins in total. It would be helpful if you could remember that this op amp ic should be powered by an 5V battery. A type of Operational Amplifier buffer op amp is what this device is specifically, to be more precise. In terms of input offset voltage, operational amplifier rates 3mV. Maintain 100dB as the voltage gain. Buffer op amp is equipped with 4 channels on the device. It is recommended that the temperature of this op amp ic should not fall below -25°C degrees Fahrenheit at any time. Linear amplifier shouldn't be used above 85°C degrees. The operating supply voltage of the buffer op amp is rated at 15V. It is recommended that you conduct this electronic part using the dual supply voltage of 16V.
