PA78DK Product Details

PA78DK Overview


In order to protect the op amps, a SOP case is used. There are two types of operational amplifiers in this circuit. In recent months, the number of terminations has approached 20. It consists of a total of 20 pins in total. It would be helpful if you could remember that this op amp ic should be powered by an 150V battery. It has 20 pins that make up the linear amplifier. In terms of input offset voltage, operational amplifier rates 8mV. In order for this instrumentation amplifier to operate, the supply current needs to be between 700μA and 10 . Maintain 120dB as the voltage gain. In total, there are 1 circuits on this buffer amplifier. It is recommended that the temperature of this op amp ic should not fall below -40°C degrees Fahrenheit at any time. Linear amplifier shouldn't be used above 125°C degrees. The operating supply voltage of the buffer op amp is rated at 300V. When it comes to the voltage from which this electrical part will operate, it can operate at a maximum of less than 350V. It is recommended that you keep the instrumentation amplifier's supply voltage higher than 20V when using it. It is recommended that you conduct this electronic part using the dual supply voltage of 175V.
