OPA345NA/250G4 Product Details

OPA345NA/250G4 Overview


In order to protect the op amps, a SOT-23 case is used. There are two types of operational amplifiers in this circuit. In the case of Tape and Reel cases, linear amplifier will be delivered. In recent months, the number of terminations has approached 5. It consists of a total of 5 pins in total. It would be helpful if you could remember that this op amp ic should be powered by an 5.5V battery. A type of Operational Amplifier buffer op amp is what this device is specifically, to be more precise. It has 5 pins that make up the linear amplifier. In terms of input offset voltage, operational amplifier rates 1mV. Maintain 122dB as the voltage gain. 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 85°C degrees. As a whole, there are 1 elements that make up this buffer amplifier. When it comes to the voltage from which this electrical part will operate, it can operate at a maximum of less than 5.5V. It is recommended that you keep the instrumentation amplifier's supply voltage higher than 2.7V when using it.
